DONT LET GM BRUSH US OFF....

thatboy092 · November 14, 2002

[:angry:] I took my car to the dealer for the knocking and the shopfore man said yes there was knocking and there is nothing they can do about it to correct it because there isnt a fix. When I was at the dealer there were 5 other trucks with the same complaint. He says that GM will respond to the problem and correct it if enough people bitch about it. The service manager said complain to the chevy marketing dept. and say that they can not advertise "Like a Rock" when it has a bounch of rattles! He has a 5.3 and it does the same thing. I think GM is brush us off and saying that the knocking is normal. Here is a number to complain to, Vic Smith he is suppose to be the UAW quality network rep for Gm phone # is 608-756-7336 or fax 608-756-7569

see ya could have did it the smart way and posted this in a reply one one of the hundred threads already going about this nonsense but you had to start another thread.. not a smart move, when it's already been posted a thousand times, over and over that they are not going to do anything and that it WILL NOT HURT THE ENGINE!!!

Johnnie aka "Mr. Johnnie" Cochran may be "the man" for the job.

"If you hear a knock or a clack, GM must take it back!" ;)

Be advised, product liability lawyers require steep retainers, in some cases. Mr. Johnnie is not one, but he will play one for the right amount of money. Without proof of catastrophic failure or injuries-(multiple and serious)-not much incentive exists for "good hearted" repair expenses. Risk vs benefit is the deciding factor. What does GM risk by not fixing, what risk exists to their profits by not fixing or fixing, what benefits do they reap by fixing, what costs less and means more profit in the long run? Do they stand to lose a lawsuit or not and if they lost, how much could it be? No one has stepped up to test it in court. Since there are no injuries or deaths reported or even engine failures, a lawyer will probably tell you that your chances are nil.

I wish those who have the problem could get an easy and satisfactory fix, but the reality is that it's not likely.

Have to agree with the Doc here.

#1) Most lemon laws say it must affect safety, value or use to be a lemon item.

The problem is categorizing it too. I would hate to see GM blow off the man with a serious KNOCKING ENGINE, by calling it cold start knock (which I call a tap).

I guess if there was a decibel and a time limit E.G.

"If your knock exceeds X decibels over a 90 second period"

Then you have a bad crank or a piston problem.

"If your knock is less than X decibels, for less than 90 seconds and occurs when you start the motor cold...."

Then you have an acceptable level of knock.

"If your knock continues beyond 90 seconds and registers X decibels.....then you have a diesel engine or deserve a new gasoline engine that does not knock....or a $2500 check and a set of earplugs whichever you choose.

Most of us know what a valve train with improper oil flow sounds like. Most of us can tell the difference between "The oil hasn't gotten up to the top of the motor yet" and "A clogged up pushrod that is starving the top end for oil."

The unfortunate thing is that when it is a widespread problem....it becomes polar, black and white. All knock is categorized as acceptable when it maybe should not be.

Hello,

To all the piston slap suffers out there....

if you do have a complaint of piston slap that goes away when warm and if the cylinders are canceled and the noise changes? this is in FACT due to the to short and to thin piston skirts used to reduce weight and increase fuel mileage with the pistons that GM installed .

As of now, if you take your 4.8, 5.3 or 6.0 L truck into the Dealer and the Service Manager knows what he is doing, you WILL get this repaired... 1st you need to call GM customer assistance and set up a case, then you will get a 100,000 mile extended warranty. Then if the Service manager calls the dealer rep, you can and will be able to get the following ASAP:

the 4.8L and the 5.3L pistons and a new crank ARE AVAILABLE

the 6.0L engine, you will get a NEW ENGINE!!!

As for excessive oil consumption GM calls excessive oil consumption is the use of more than 1qt in 2000 miles in the 4.8L , 5.3L engines . if your 4.8 or 5.3 is using excessive oil, 1st you probably need a new style orifice PCV valve and the valve cover inspected and possibly new lifters depending upon when it was built and the engine size.

Unless you have the 8.1 Liter engine. which states " the use of more than 1qt in 100 gallons of fuel used is excessive"

and on this engine. then the intake bolts and intake gasket would have to be replaced if it is actually using too much oil.

Hope this clears things up for all you GM Owners and this is 100% ligit!!!!!!

Quick question- If I don't have excessive oil consumption

or knock in my 2001 5.3 than should I still have replaced

my pcv valve with the new type(no guts)? I did get a 100k

powertrain warranty by bitchin about my driveline clunk so

if I start gettin the knock I'm all good (I hope).

Thanks!

Just a friendly Mod note:

DO NOT go by everything this guy says until there is proof that he is in fact a GM Tech.

Thank you

Thank you

Well put Larry.

For every ones information: This board can not substantiate these claims until we can confirm a TSB# or hear otherwise from GM. Please do not go to your dealer and start ranting and raving saying "It's true because I saw it on GM-Trucks".
