Anybody taken theirs in? What's GM saying about this? Engines aren't supposed to knock, man.
Anybody know of any good Super Duty Forums?

I think I've got my air conditioner problem taken care of (I hope). I took in for the 3rd time and this time I left it running in front of the service dept. I had been on the freeway on the way home and it quit on me again so I drove it right around to the dealers. I told them I wanted a mechanic to look at it while it was still not working and they got one out there. He ended up replacing the cycling switch. So hopefully it's fixed...won't know for sure until I've tested it out.
Checked on the price of my filter change and the filter was $23.85 but the guy behind the parts counter told me that the new price will be $14.
GMC tried to sell me a 5 year extended warranty.. sent me a letter in the mail, but you have to read the fine print.
It really is only a 2 year warranty as the 5year starts at zero miles, it isn't tacked on to the end of your 3 year warranty like it should be.
4964me1: I first noticed the start-up knock @ 1300 miles, didn't make me too happy, but I guess I will at least get the extended warranty out of it. Now to schedule a hearing session with the service department...

By the way I had a bit of a problem trying to grease the lower ball joints. I bought a grease gun with the rubber hose as suggested by others, but both the lower ball joints wouldn't accept grease, it just kept making a mess. The tie rods and upper ball joints all took grease no problem...any suggestions anyone???
2001 2500HD 4x4 with 8.1/Alli
Bob
Question - Which Alli does the HD's have - 1000, 2000 or 2400 Series?
What is the AC Filter No.?
($23.85 or $14.00) Will look for replacement brand -- Alli does't give a filter no.! Oh! bet I need to look in the vehicle owners manual--
Alli OM3063EM say to DRAIN the trans.
Just to change the FILTER?? Is that right?
How many Qts of fluid does that Drain??
Thks -- 75v
The part number for the external spin-on filter is 29537268. I assume that is an Allison number, I picked that up from either the dieselpage or pickuptruck.com and just jotted it down so I hope it is right as I haven't verified it yet (only at 3,000 miles)
From what I read in that service manual for the 1000 series you just have to change the external filter at 5,000 miles, no mention of a fluid change at 5,000 miles.
Hope this helps...

For the individual that inquired about Eagle Aloy wheels. I have a set of Eagle 115's, they run great with no vibration.

I have the knock that all are talking about, I'm thinking about unloading this rig before the word is everywhere. (2300 miles) I have the only 8.1 over here at the moment.
Also, anyone need a set of front Huskyliner front black mats for a 2001HD ext cab? I have an extra set. email me at: omcniff@yahoo.com if interested.
Or try Mobil 1 ? Stick with Valoline 5/30w?
Any wine drinkers out there ?
Just had a bottle of Fess Parkers Chardonnay, Marcella's Vineyard. Very refreshing, slight sweet taste, butterly to the palate. MMMMMMM!!
Bob
Also, it seems that everyone that has had this done, gets the knock back a few thousand miles later. Does his then become a maintenance issue> lube/oil/filter/decarbon pistons?
-Eric
That is a good question, for those that have had the soak done on their engine, did the oil need to be changed afterwards?? Sure would pi$$ me off if it did as that would be 26 bucks for the synthetic oil down the recycling tubes!!
Bob
1. "Well, the 8100's ALL knock when you start them up."
2. "GM says that a quart of oil every thousand miles is "normal oil consumption"
Correct me if I'm wrong here, but experience has taught me that if your engine knocks when you start it up and burns a quart of oil every thousand miles it's not going to last very long.
A friend of mine builds engines for the local race teams, dirt track circuit... He was helping me build an engine for my old Cutlass and he gave some helpful advice: "Well, if it knocks or burns oil, take it out and tear it down, because you obviously screwed it up when you put it together."
Is the 8100 going the way of Buick's infamous 231 V-6? Anyone here interested in a class action suit?

Gm's position has been for the last 30 years that a qt in 500 miles is normal- That's why i switched to Ford in '90 but now i'm back so hope gm had learned something.
Sounds like gm 'Soak Deal' referred to here is an attempt to remove carbon elements building up on pistons.
I would offer this- If carbon deposits are the issue they will provide hot spots in the cylindars and can cause pre-ignition which may be related to the knock being refered to.
The root cause is to determine what is causing the carbon deposits-- they could be an issue in any engine.
The only source for the carbon is either the Fuel or the Oil being used. The fuel blends are different from season to season and locations around the country as well as some cities require ther own blends etc. So one brand may not be the cause in one area and is in another.
Opinions pro & con??

for your truck. It won't be a number at all but
a six letter designation like, "DMZXNN".
2. Call Cheverolet, 1-800-222-1020 and get
customer service (I'm not sure which menu
selection). Give them your order number and ask
for your vehicle identification number, "VIN".
3. You can use the VIN at www.bnsf.com to track
your truck. You'll figure out how. Explore.
Yours must have rolled off right in front of
mine. I called today, and they said although
mine's been built it hasn't been released yet.
Something about still being in smog
certification.
Have fun, David

Lots of plow heads over there to help
you out on plow stuff......
As far as truck stuff THIS IS THE PLACE !
Try the 2500-3500 thread here too.....Geo
I ordered my truck May 25th. The order was accepted (an allocation was given to my dealer) in the same week as yours. This length of wait is not unusual. What with "on time delivery", Ryan is right about a possible option delay. But yours should be rolling off any day. Besides, with all the "squeaks, whistles, rattles, shudders, shimmies, knocks, etc. we hear about here, I'd be more concerned about getting a good one than a soon one! Pray for a late snow and relax. It'll be here "on time".

his reply: "But how do you know it's burning oil?" I said "two quarts of oil went SOMEWHERE, and it didn't LEAK out." He says: "but how do you know it's burning oil?"... They got some real freakin geniuses working over there, I tell you. So today the kid calls me up and says "Well, I ran it, and I didn't hear anything knocking" Typical. My girlfriend heard it. My friends heard it. Even my MOTHER heard it.
Doesn't look too promising getting anywhere at the Chevy dealer. Anyone else get anywhere?

If I understood the article correctly, the oil consumption was based on driving habits where you would have the engine at higher RPM's with a light load.
Also, I'm sure its not news to anyone that they "don't build them like they used to". After the first 1000 miles even the weatherstipping/sealer trims (from the bottom of the doors and inside edges of the hood) started falling of. Must have been put on before the surfaces were properly cleaned. Any guesses on whether the dealers going to give me a hard time when I tell them I want them all replaced.
Appreciate any help anyone might be able to provide on my wiring question.
Thanks,
Jim
Piston design: 2
Lifter noise: 2
We have no idea: 1
All of them agreed that it's "normal" for GM engines to knock. I'll agree that while it may be COMMON, it sure ain't normal. One guy actually said there's a fix. They're offering to tear down the engines and replace the pistons with a new polymer coated piston, but nobody as of yet wants their engines torn apart because who knows what happens when the polymer coating wears off. According to all the service managers it's not detrimental to the engine, because GM is telling them it's "normal". (just because they all knock, that doesn't make it normal.) I managed to ask a couple of the mechanics what THEY thought and they both said "Sounds pretty ****ed up to me. I'd get rid of it." So the guys who went to automotive school and passed all the ASE certification tests think I should dump it. What do you guys think?
This is driving me up the wall now, I have read so much, so many problems, possible fixes, no fixes, blah, blah, blah. One thing I did read I think on pickuptruck.com that one guy had an oil analysis done at 12k on his 6.0L and showed high amounts of Copper which relates to excessive bearing wear I guess...so next oil change I am going to spend the 18 bucks and have one done and see what comes back. Probably have to do a couple to get a trend, but if it has high amounts of Aluminum or Copper I am gonna freak out!!!
Will let you know what the service department tries to pull over my head as ab excuse tonight or tomorrow..

No matter how long you let the engine warmup, 1-5 minutes or how clod or warm the outside air is, the Allison will not shift out of low range until you drive 1/4 to 1/2 a mile. Then, after that it shifts at 2000 rpm and everyting is fine. Any comments ?
DOH!!
I just took my truck down the road to check the oil pressure: idling (700 rpm) with temperature at 195 deg., oil pressure is 28-30lbs. It stayed at around 40 lbs. until after being near that temperature for a few minutes. 20lbs seems low.
1i2cu; Checked your interests during the drive. Mine shifts at around 1800 rpm (14 mph) no matter what the distance.
-David
1i2cu, mine shifts at 1800rpm,but hangs there untill 14-16 mph, hot or cold. My truck also stays in a lower gear untill speed increases to a shift point; so, for instance@ no load, at 30mph on city side streets it will hang in 3rd, and wont upshift to 4th untill 37mph, hot or cold.The shft pattern is unlike any other truck I have ever owned.

So I picked it up on Sept. 4th.
JR buddy, it's worth the wait. This baby's awesome! Hang in there man.
Forgot to mention the delay in answering. I only have access to my computer on weekends. Sorry.
