Quite a few toy boys crying about knocking
I-force v8s....and lets not forget the
sludge issue ! NO auto maker has troublefree
vehicles.
Sure up here in frozen NY I have the cold start
knock..but now its summer NO KNOCK at all.
ALL my cars and trucks from Caddies to Toyotas
have had a cold start knock in winter time !
And all the dealers said CONDITION NORMAL !
LOL.....geo
Will be passing through your way next Thursday on way to Kingston, Ontario Canada for the annual dog show/camping trip with wife and kid. Then again on 8/14 to Brockville, Ontario. I'll wave as we go over the bridge or might be able to stop for a quick brew. LOL

I was able to talk to a engineer at GM powertrain regarding Oil Samples. This was his job, oil sampling. Well, he got into alot about the methodology of sampling. The equipment used and the reports he has generated. The way this gentleman talked was very candid. What it comes down to, is the in one way he is suprised as to how low the copper in my oil reports have come back as he has seen up to three times that amount in normal oil samples.
He is not suprised as to how low because of the sampling method used by the lab. Apparently the lab I used uses a plasma flame to burn the oil and then a gas chromatograph with give a spectrum analysis of the makeup. The flaw here is that larger particles will not burn and therefor are not represented. This is the "Cheap" method. Apparently the more expensive labs use a much more costly method that measures on a microscopic level.
I did some checking and there appears to be alot of evidence to support this.
As to where all of the copper is coming from? We will see as I have another conversation coming up...
One short note, BBB told me twice "Chevy says it's not covered by lemon law". I had to push BBB (even through my 20 work slips for the first 1 1/2 years) to even get them to set the hearing. Did the hearing in writing, which worked good. GM's only defense...the oil leaks from the side of the motor weren't related to the knocking (even though they were on the same side of the engine) and our visit in December of '00 wasn't in the first year of ownership (purchased in April '00).
GM got an awakening from the decision, but still messed with us on the interest and collateral costs (which we never got).

Here goes: Would anyone in this thread w/ the knocking problem still recommend a Silverado?
I really like them, and my dad's has the 5.3 and he has no probems so far. Do you know more people who have the problem, or more people who don't? Is it possible to hear it in a relatively short time, or does it take over a year to crop up?
Also, does anyone have any info/links regarding this problem in the 3.4 v6? We bought an Impala last year and so far, so good. But I've heard (a few times) that this engine is susceptible as well. Please respond.
More than likely all GM products are susceptible to this problem, although not all are afflicted. As rumor has it, EPA requirements are ever demanding fewer pollutants; Looser clearances are GM's solution. That's one problem. But what is even more aggravating is GM's response to customer complaints. It is a cynical mockery of the warranty system, making the warranty of little value when major complaints are simply defined as 'normal'.
The truck? I love the thing, ha! You gotta give the engineers at GM a lot of credit. It's a great truck; However, in need of a few refinements. Would I buy one today? I recommend patience; Wait until you know for sure this problem is solved. I think eventually it will be if not already. To find out, talk to people with 03's with at least several thousand miles, talk to mechanics who work on them, and as you are doing now, use the internet.

I hope you have better luck than I did.
As far as the '03 goes, I just saw one on the lot today... they're now using the front end off the avalanches (or it looks similar anyway). Uggggly, IMO. I wasn't in any hurry to buy one. Now I don't know if I would, even if they do finally solve the piston slap problem after 3 long yrs. The new look is a big mistake for chevy. At least for my business it is.
I thought they were (GMC/Chevy) the best looking trucks out there. Followed by Ford/Tundra (I lump them together b/c so similar, Toyota obviously copied F-150, and rightfully so since it is the best selling vehicle for so long). I thought the new Rams were way overdone. Like a big pig snout. I was just starting to get used to them. Now, the new Chevy is actually making me think they look good!
Only problem ever w/ the Mazda was a leaking tranmission (5 spd). It was very common. A seal leaked in transmissions built in Japan (I think). They usually replaced the seal. My friend went all over town till he finally found a freeze plug that fit in the hole. No more leak, and probably a longer term solution than a new seal
My dad's '88 Ranger (2.9 L, 5 spd) had the same problem, and it is the only major prob. he's had w/ it so far (replaced water pump and heater core also). He still has the truck.
I want an extended cab that people can actually take trips in. This ruled out most small trucks, the Tundra, and the old Rams. The F-150 supercab is OK, but the seat back is too straight for more than 30 mins. or so. Chevy is best choice, IMO. Anyone know how the Dakota quad is? The leg room looked great on paper, but I've yet to sit in one. I will have to look at the new Ram also. An SUV would fit as well, but I'd rather have a bed.
As a side note, I hate when seats are low slung, like you're sitting on the floor w/ your legs sticking straight out. The Isuzu Rodeo, Nissan Pathfinder and Xterra really annoyed me in this respect. Tacoma wasn't great for me either. They felt more like sports cars than SUV's or trucks. Must be a Japanese thing.
I loved the Isuzu Trooper, though. Best SUV I test drove, overall. I may get one of those, if they're still selling around 20K when I buy. I hear they're very reliable. And no engine knock. I think the engine (3.5 L DOHC) is GM sourced too!
Sorry for getting too off topic w/ last 2 posts, pf_flyer.
I don't know why Ford won't upgrade the rear seat on the F150. It is the reason my wife didn't like my '95 Supercab (otherwise a fine truck). I guess Ford wants to push buyers to a Supercrew.
I did consider the Dakota before buying the Mazda. I had some concerns with Dakota reliabiity and gas mileage, but guys I know who have Dakotas have had good service from them and haven't complained about gas mileage. The local Dodge dealers aren't too great - another reason why I got the Mazda. The Dakota might be the best buy for you. I agree with you on the styling of the new Rams.
By the way, my Mazda has a 5-spd automatic made by Ford in France.
I see you live in Lubbock - GO TECH!
Heck yeah! We might surprise some this year. Unfortunately OU and UT are prob. out of reach. A&M will be motivated after what happend last year (and it's at Kyle Field- darn). Also, we have a top 5 strength of schedule, a rarity for us (especially as far as non-conference goes), oh no!
If you don't mind my asking, what part of TX are you from? What dealer did you get your truck at? Did you have more problems w/ dealer, or w/ GM?
I've been hearing the dealers are nice enough, but their hands are tied (GM). Was that your experience?
I know a lot of guys who own GMCs, and none of them have complained to me about their dealers. You are right in assuming that GM ties their hands. On the other hand, warranty work provides steady business for a GMC dealer. It is only when a customer walks away from GM does a dealer really suffer.
I did find the local Ford dealers to be jerks in general. Three of them tried to make me deals on a new F-150; all three offers were so bad as to be insulting. That's another reason why I chose a Mazda.
I guess what I meant was, it seems like most people I know have better experiences at GM dealerships than others. Too bad GM has to screw it up.
We were looking at the Taurus. At the time (2001), base models were advertised (written on the window) for around 16,500 after rebates at another dealer- Gene Messer Ford in Lubbock. This was not selling price mind you, though it was a decent deal. This was MSRP - rebates and incentives. The one we wanted was just above base model, advertised at Gene Messer for around 17,000.
Well, the salesman at Pollard made us test drive the one we wanted, then brought us in- even though we told him 3 times we were not buying till 4 weeks later (we wanted to save some money).
He wanted to know what payments we were looking for. We said, "we aren't looking for payments- what's your best price?" He looked straight at us and said, "how does $410 /month sound (on a 60 month loan). Yeah right. (financing was already really low at this time- Sept. 2001 and we had a trade in and planned on a down payment)
We said,"we told you we aren't loooking for payments, we have financing already, but if we were, $410 a month is ridiculous- and it certainly does not come from your best price. We said, "$410 a month is too much for MSRP on that car, and we know there are rebates on it." He said, "It does? Hold on." He leaves, for a loooong time, then comes back and says
"I spoke w/ my manager and you're right, it does have a rebate. How does $390 a month sound?" We said "how does around $330 a month sound?" He said, "I can do a lease for that."
We left.
At home, we ran the numbers on a loan for $17,000 for 60 months at 6.5% (from our bank)- it was $353/month. That was w/ tax and all, and w/out our trade in or down payment. And that price was MSRP essentially (only giving us the rebate, no special "deal"). He was trying to get us to pay at least $40/month over MSRP on a 5 yr loan!
What a waste of 1.5 hrs!
We happily bought an Impala from Scoggin-Dickey Chevrolet in Lubbock in October.
Dealerships are ran by people- and unfortunately some people are not very nice. That is why the next time I buy a vehicle I won't mind going to look at Fords again.
In fact, Pollard Ford might be a good dealer overall. But I probably won't go to that specific dealer again, just as a matter of principal.
This truck was apparently less than a month old.
With less than 1500 miles on it I think I heard the dreaded piston slap. It is hard to tell. It seems that GM is getting very sly on this one. The 2003's are all drive by wire and it appears that cold, the PCM commands a higher idle than previous years. This may be to heat up the pistons quicker at an idle that would not present the piston slap.
Starting it up yeaterday morning it idled at 1100-1200 rpms for about a minute. My 2001 does not flare that high for nearly as long....
Walter
Mine is at likr 5-600 in the warmer temps and 1000 in cold temps
Looks like the new taillights will fit on a 2001.
Also the 2003's have the lighted entry on them.
If it is dark enough they will light the DRLs and revers lights. This truck had the curbside lights under the mirrors.
Some cool new things. Even though I don't like the window switches..

trip - about 3K miles - I am not a slow driver -the first 700 miles took 10 hours - including
stopping for BR breaks and gas, I was driving 85-90 MPH and still getting passed. Also spent
time driving in Rocky mountains - truck in 4x4 -snow covered road. This was by far the most
difficult miles I have put on the truck.
BTW - I switched to M-1 before the trip -
When I left Houston the temp was 90 degrees - the first start up in Colorado was -10 (truck sat
over night). I expected to hear a loud knock at start up - but engine was quiet. My knock is gone
- and has not returned - I now have over 33K on the truck.
The only time I hear a knock now is after changing the oil - lasts about 3 seconds - and I consider
this normal.
XYZ, Driving high speed or in 4 wheel drive is not the same to me as pulling a 6600 lb. trailer over hill and dale at speeds of 70-75 mph. I've logged 2500 miles on truck pulling this trailer this year and it's definately made a difference in the audible and longevity of my knock issue.I also only had the knock initially for 5-10 seconds, now it lasts much longer and is much louder too! One thing you've done I have not is switched to M-1 oil, maybe I'll try it but never was one to believe in syn oils especially at the price they get for it.

119 days in the shop, 3 engines. Insulted by the regional rep, yelling at a friend of mine who owned a fleet of GM trucks, "IT'S NOT A GM PROBLEM". Sounds
like GM still doesn't care about it's customers.
The reason why my trucked rapped, the oil journals where drilled incorrectly in the crank shaft. GREAT!!! in all 3 engines. Talk about premature wear out.
Dumped my GMC.

As for GM, well I received the semi-worthless 6/75 Major Guard, not that it will do any good. Bumper to Bumper $0 deductible is worthless if GM won't admit there is a problem.
Enough ranting, pour me a glass.
-Eric
Ray T.
How did you manage to get the 6/75 major guard?? Did you have more issues then just the piston slap? Worthless is right, since they tell you everything is normal to avoid doing anything!
The glass is poured and waiting for ya LOL.
Ray T.
Does anyone know whether receiving an extended warranty for the knock issue may disqualify one from consideration in the event of a future settlement of a class action law suit? I'm wondering if it could be argued that the extended warranty is a valued compensation already received. Any opinions? Any lawyers out there?
