    There is an old statement about misery loving company. BELIEVE IT.

    Something about "happily married" just seems to be a parody of terminology. But hey, I could be wrong.

    When you think you've found the right one...you get married....and wake up and find a person you don't know....

    Without being redundant...anyone got an 8100 that knocks like a diesel?
  • noobie1noobie1 Member Posts: 326
    No. Thank God. Only a clickety - clickety when you first start it up. Kinda like a '52' Olds with about 80K. I'm not complaining though. It's minor at this point.

    Coming from a '89 GMC SLE Extra cab, yep that is one of the years where the paint just falls off. Truck in shop now, getting new paint, want to make pretty to get rid (aahh.. sell) Bought new in '88, 95000 on it and still runs pretty good. Going to hate to go from 16avg mpg to maybe 12?

    Would love any tips/tricks on new GMC.

    Sorry for taking a bit to get back to you, I was out all last week...
    I have not done anything about my knock as it went from 30-45 seconds to about 10 after 1 can of BG 44K so I am waiting a bit longer to see if I can make it completely go away.

    Quad
    I have not tried Burt or Len Lyall, but have heard good things from Burt and will probably go there if anything should crop up and see if things are better.

    I changed my trans filter last week at 4,960 miles. I got my filter from a large truck shop that supplies parts for the Allison 1000. Dealers either told me I didn't have the Allison (they supposedly verified this by my vin) or they told me it was gonna cost $25!! Went to a large truck supplier shop after looking it up on Allisons website and got the filter for $8.34!
    By the way I told the guy at the parts counter what the dealers were trying to do and he stated most of them buy the filters from them!

    After 1700 plus miles, still love the truck. The Kelly AWR tires are wonderful. Wet traction seems fine, the mud traction is worlds better than the stock tires. The 1 1/2 inch increase in ground clearance is great too. The road noise is minimal with the kelly AWR tires. The only rub on the drivers side rear well by just a little bit, and I am sure I could fix this very easily, but it isn't very much of an issue right now. I didn't have to trim the air dam or adjust the torsion bars either. I think these will be great tires, and they finally make the truck look right. (Warning, purchase of these tires will make you want to spend several hundred on side steps!!!) The speedometer and odometer now read off by 9.3%. The odometer shows 91.5 miles after traveling 100 miles. When it shows 100, I have traveled 109.3 miles.

    The RPMS were

    Before with 245 (.71/1) now with 255x85 (.71/1)
    60 1760 2479 1610 2268
    75 2201 3099 2013 2835
    85 2494 3515 2282 3216

    Worst tank has been 12 mpg with no trips over 5 miles, 17 engine hours and an average speed of 14 mph. With lots of towing. Best tank was 2nd tank with 19 mpg, before adding tires, and during break in. Got 14 last tank with the new tires (after adjustment), but this contained city, country, towing and some high speed interstate short distance.

    Took 2 hours to install the right sided Westin CPS step and 1/2 hour to install the drivers side after I figured out how to do it!!! hehe

    Best of luck

    Does anyone have a part number for a Mobile 1 oil filter,(to fit an 8.1 gasser) or a good quality brand that incorporates a anti drain back valve? It time for the 1st oil change and the Delco PF454 does not offer a drain back valve, so I am told by my friendly GM parts dept. Any help would be appriciated, and where to purchase the same----Thanks, Sir-col
  • bobsquatchbobsquatch Member Posts: 136
    Check out this web site. It sells an anti drain back valve that goes between the filter and the filter manifold. Models for most vehicles can be found here.

    Did I understand (or perhaps misunderstand) a ways back in the postings that someone's financial advisers think you should have used home equity to buy a vehicle instead of using 0% interest financing?

    If so, comparing that to non deductible interest rates, remember two things. The first is the way a tax deduction works it requires that you spend more money than you will get in deduction, so your money is gone anyway. To clarify that, if you are in the 28% tax bracket and you spend $1.00 in a tax deductible manner, your deduction is only 28 cents. You have spent an additional 72 cents to save 28 cents on your income tax. I don't know about you, but I'd rather keep the 72 cents and give the IRS 28.

    The point being, if you are in that situation, don't just assume it is better to go with a tax deductible form of interest. Compare the deductible interest to a non-deductible form to see which is saving you more and go with that. Check your last tax return to see what tax bracket you are in, and, if your income hasn't changed considerably, use that as a comparison. For example, if you can get a tax deductible loan for 10% or a non-deductible for 7%, which is better? Again, if you are in a 28% tax bracket, and use the deductible interest rate you will get a tax deduction of 28% of that amount (10%- 28% of 10%) or 10%-2.8%, which means you would pay about 7.2% interest after the deduction. Since you would be paying interest on the 10% all year when you could be using the money elsewhere it will actually calculate a little higher, but for ease of figuring, you can see comparing that to the 7% means it is costing you .2% more. All of that is assuming you are going to finance the same amount using either method.

    The second thing is, when you borrow money against your home it is increasing your mortgage by that amount and extending your exposure to bad luck and the possibility of foreclosure, which I am loathe to do.

    I recommend you look closely any time you buy something in which you must pay interest, and if you get a 0% rate, assuming you can use it after you get your best possible deal and not just if you pay MSRP, TAKE IT! Even if you must pay MSRP, check your payments at MSRP with the 0% rate versus your best deal with a deductible interest.

    The term "tax deductible" seems to sedate some, and they ALWAYS want it, but it isn't always the best.
  • cowboyjohn1cowboyjohn1 Member Posts: 125
    Amen to what you said. I totally don't understand when people say "I have to buy something to get more tax deductions. I am paying the IRS too much money." It is obvious they like to give their money to someone else. Loan companies love them. The other one that advertisers use a lot is "It is tax deductible." Mostly that is BS. To make most things tax deductible (not interest on a house or business expenses) you must use Schedule A. If you must use Schedule A, that simply means that a lot of your money is going to someone else. Keep up the good advice, cowboyjohn
  • quadrunner500quadrunner500 Member Posts: 2,721
    I'm not sure if this was referring to me or not, but I never said 0% interest because it wasn't offered at the time. Secondly, the notion that paying the IRS $0.28 is better than spending an additional $0.72 to get the deduction is utterly silly. No one is taking out loans to get tax breaks. We take out loans to make a purchase. Just paying IRS the $0.28 saves you the $0.72 spent additionally, but you don't have a truck to show for it!

    I may be late, but I would can the dual battery option. I can guarentee it will result in a delay.

    According to www.wheels.com
    the dual battery option is still on hold
  • bmaigebmaige Member Posts: 140
    Sorry if you thought I was picking on you, quadrunner500. That was not my intent. I just got on my soapbox concerning tax deductions and sometimes the bubbles get in my eyes when I do that.

    If you read my comments carefully you will see I was referring to tax deductions generally when I said in a 28% tax bracket a deduction means you are throwing away 72 cents of each $1.00 to save 28 cents and I'd rather give the IRS the 28 cents and keep 72 cents.

    There are those who feel the more things they can buy that are tax deductible the better off they are. Taxwise that is true, but moneywise, it may well not be. Since this is a pickup forum, let's assume one is in business and uses pickups. Is it better to trade a perfectly good pickup that is paid for and fully depreciated to get a new one to provide tax deductions? If one does, and there is no other reason for trading, he or she is in the category of throwing 72 cents of each $1.00 of deduction away to save 28 cents on his taxes. Is that saving him taxes? Yes. Is it good business? Unless it affects his taxes favorably enough to offset that wasted expenditure, not in my book.

    Many in this forum are not in business so our pickups can't be depreciated for tax purposes. If not it should not be assumed tax deductible interest is the best moneywise. I suggest very strongly that one compares deductible to non deductible interest rates that are available, and determine which will cost the least when the loan is paid in full and the title to the truck is handed over. It is a simple matter of good business.
  • mgdvhmanmgdvhman Member Posts: 4,157
    .But if you are going to buy a vehicle....and have to get a loan...why not tax deductible?

    although a home equity is supposed to be for home improvement... many people use it for other things anyway....

    Just have s real good reason for doing it when ya get audited!!

    haha

    ...and just cuz ya use a Home eq. loan doesn't mean you have to declare it as a deduction.

  • quadrunner500quadrunner500 Member Posts: 2,721
    I do use it for business. I did trade a truck that was fully paid for...(not doing very well so far)...however I own the truck personally, and take a mileage allowance for business use.

    I have a 2001 2500HD CC SB with the 8.1/allison, but in the GMC flavor. The only issue I have is the cold start knock. Other than that the truck has been flawless.

    On the other side, it has a ferocious appetite for petroleum.

  • 4x4man4x4man Member Posts: 222
    Got a good laugh on that until I remembered that I needed to fill up this afternoon with only about 183 miles on it at 1/4 tank...Guess a little too much hot rodding last week!!

    Kanton1-
    I have a 2001 2500HD Ext Cab SB with 8.1L/Alli and the truck is flawless out side of its cold start "normal" operation.

  • kanton1kanton1 Member Posts: 41
    Good to hear others are not having the same problems. I figure mlempire just got a bad one. I had a 2000 1/2 ton that had only a couple very minor flaws, so that eases my mind somewhat.

    Just purchased a 2001, 8.1 w/Allison. impressive truck. Got 12.4 on second tank probably do better if I could keep my foot out of it.
    Have the same startup knock sounded alot like my 86 Ford 5.8 not to worried yet.. Would anybody like to suggest what type of tube steps to get..
  • eric2001eric2001 Member Posts: 482
    I like the Westin CPS (platinum series), so I put a set on my CC. The bottom line is personal preference, but here is a link to westin:

    They installed very easily, too. Simple bolt in, no drilling involved.

    Just got my test results back from Blackstone Laboratories on my last oil change. My truck is an 8.1, Allison, CC, SB, GMC. Truck had 8,600 miles on the engine and there were 2,600 miles on the oil. I have no cold engine knocks or other noises. Oil comsumption has been one quart every 1,500 miles. Fuel consumption has been 10 to 12 mpg. Blackstone reported I have high wear indicators (iron, copper, lead, silicon) which are common in new engines that are still undergoing break-in. They also said the flshpoint on the oil was normal so it isn't running too rich. I wonder how long before break-in is complete and if then my oil comsumption will taper off.
  • 4x4man4x4man Member Posts: 222
    I agree with Eric, go with Westin CPS. Installation was easy, the directions leave a bit to be desired though. Chrome plated stainless steel is the way to go if you are going to keep your truck for a while. I got mine through Summit Racing for $371 to my door for my extended cab 2500HD.

    Bob
  • 4x4man4x4man Member Posts: 222
    I will be sending an oil sample in to Blackstone when this oil has 3k on it to see how everything is doing in there. Truck will have 6k on it by that time. $20 is good insurance to make sure everything inside the engine is "playing" right. I would've thought by 8,600 miles the engine would've just had higher levels of silicon (seals, gaskets wearing in) and lower levels of copper and lead, but I guess not.
    So far my oil is only down 1/4 of a qt in 2,100 miles, I will be happy if it will be like this forever!!

    Sorry for the ignorance but I just bought a ford and the reason I didnt get the factory nerf bars is that they are body mounted. So far all of the aftermarket I see are also mounted to the body including westin. Looks like I may have to make my own.
  • obyoneobyone Member Posts: 7,841
    Only ones I seen are mounted to the frame. Don't think any part of the body could support the bars and someone standing on them.
  • eric2001eric2001 Member Posts: 482
    The Westin bars bolt to the bottom of the cab mounts (3 on each for GM crew-cab).

    Dean: had a set of DeeZee SS bars on my '99 that were mounted to rocker panels. Removed a couple of plastic cups, and the steps bolted with oversize washers. The bars were designed such that they braced the rockers so as not to bend or flex the panels.

    On a bad note, when I was broadsided back in February, the bars were destroyed, caving in the rockers and floor panels, preventing more damage to the frame. The bad part was if I didn't have the bars, my frame would have most likely been twisted beyond repair, and the truck would have been totaled. So instead I sold it to the bodyshop and took the loss...

    Hey guys, I still have an extra set of front floor mats for a Chev/GMC 2500HD ext cab.
    (Black-new in box))These things fit great.
    Anyone interested?

    My GMC is starting to get a warped rotor wobble at 4k miles. What's up with that??!! I just put a 3rd set of rotors on my 2000 Cherokee that has 10k, and my 99 Cavalier just got a set. Rotors must be getting some cheap iron.
  • emthoustonemthouston Member Posts: 12
    Recently had a Rhino liner sprayed in, Westin Black nerf bars, and Wade rail caps installed. All looks real good with the Lt. Pewter paint. Gas mileage is not real good. I recently took a trip to Louisiana and got about 14 on the highway. Around town is close to 9. You can't let it idle very long as it drinks gas almost as bad as local driving. Truck drives and performs great. Lots of power.
  • bobsquatchbobsquatch Member Posts: 136
    Might want to check your driving style. If your vehicles are automatics they use a lot more brakes to come to a stop and then you hold the brakes to keep it from powering forward. This causes the rotors to get hot and the pads to get extremely hot. The hotter pads then clamp onto the stationary rotor delivering uneven heat to them causing a slight warp. Repeating this dozens of times causes the many distortions you feel in your pedal and wheel. The solution, drive your auto like a stick. Downshift to help slowing and stopping then put in neutral and release the brakes whenever possible. If you stop really hard, try to stop early and then gradually roll forward as long as you can to distribute the heat evenly. Good luck.
  • minikinminikin Member Posts: 389
    blow your horn a lot and don't ever use the brakes.

  • owenm1owenm1 Member Posts: 29
    Thx for the advice on how to make rotors last longer. There are better materials to make rotors, but these car manufacturers will continue to use junk if the cost of replacing rotors only falls on their shoulders during the first year.

    I still have those mats up for grabs!

    8.1L/Allison,3.73,Ext. Cab,LB,4WD, Snug Top

    Gallons 189.8, Total Miles 2754 = 14.5 mpg

    Not bad, but puzzled by some of the results. They ranged from 13.2 (which is about what was expected) to 16.1!! And, contrary to expectations, the best results were yielded at higher altitudes. For instance, the 16.1 was from Kingman, AZ (3341 ft.) up through Flagstaff(6910),down and back up to Durango(8523). Over a hump, then back up even farther. 469 miles on 29.07 gallons. I was so surprised I double checked and even calculated the map mileage to be sure I hadn't goofed it up. It came within 5 miles of indicated.
    I've got a theory about it but unsure if it holds water: the computer controlled injection is supposed to adjust the fuel mixture to compensate for atmospheric changes (altitude). I'm suspicious that it's over compensating through some bad input like a faulty oxygen sensor or something causing it to run very lean. Someone please correct me if mistaken.
    Had to drive it like an old guy to get this result. Never set the cruise over 65. Occasionally overrode to 75 for passing.
    Also, dropped the break-in oil at 3258 miles. That's sure to make some shudder. Time (and miles) will determine the wisdom of waiting that long. Consumed about one half quart to that point. So far, after 1577 miles since change, less than one quarter. The change came in Borger, TX. Country Chevrolet Inc. Lube, oil, and filter, $29.95. Switched from 5w-30 to 10w-30 and lost most of the clickety, clickety at start up mentioned previously. Dry lifters very likely. I expect the remainder to vanish with an anti-drain back filter if such a thing can ever be found. Anyone else have any success finding one? Sir-col?
    All-in-all the truck is a very fine ride. Practically flawless. Highly recommended to anyone shopping.
    BTW - If you ever try cajun deep-fryed turkey, you'll NEVER go back.
  • mgdvhmanmgdvhman Member Posts: 4,157
    ...you said a mouthfull there!

    ....even just plain deep fried is good.....and a whole lot quicker..

    - Tim
  • noobie1noobie1 Member Posts: 326
    Right on both points, Tim. We tried one cajun, one plain (18 people). Each, excellent. Cooking time, less than two hours for both. Only possible trouble, clean up. You gotta make sure you do it in an area of little concern, or protect the area of a three foot radius around and beneath the fryer. That hot oil slops all over the place during cooking.

    had deep fried turkey for this first time this past weekend and i must say its the best turkey i ever had
