If top engine clean makes a difference than that knock is not a piston slap(serious) but is a carbon knock(not so serious) carbon can be removed by proper top end cleaning and kept off by modifying pcv system so vacuum doesnt pull oil in to induction system. This is nice convenient way to avoid engine swap headache IMO.

</font><blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote:</font><hr /><font size="2" face="Verdana, Helvetica, sans-serif">But from what I understand, GM isn't replacing any engines whether or not it is under the 3/36.</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">I purchased a 6.0L motor condemed with "piston slap." I purchased this motor from a local dealership who had the motor removed no more than 2 months ago, so YES they are considering buy backs.

General remarks:

I have had the opportunity to tear this motor down as this is going to be my project motor. It has 31,100 miles on it and after removing the heads and replacing the rotating assembly I would be hard pressed to think that there was any real problem. It had no scoring in the #5 cylinder which was the condemmed "piston slap" cylinder and all the motor took at a machine shop was a heavy hone to accomodate my new .005" over pistons.

All I'm tryin to say is GM is taking care of real problems, maybe not all but they are addressing them and even some that are not. If they were to open the flood gates and allow every knock, tick and clatter complaint result in a replacement motor we would not be buying $30,000 trucks anymore because guess what, we the consumer always pay the price for these adjustments and we will now be buying $40,000 trucks. False claims and mis-diagnostics will effect future sales costs and not in a way that favors anyone.

Get your issues documented, get the problems properly diagnosed, seek out multiple opinions/dealerships for repairs and don't go around making threats of lawsuits because who want to help someone who has said they were going to sue your anyway?

Think about it... What happened to the resale value of V8 domestic cars during the gas crisis? Resale dropped...was this a result of the manufacturer's inability to produce a quality vehicle? NO. It was consumer demand for something more efficient. Does this mean that vehicles manufacturer should be held accountable for the consumer's changing demand or the changing market? NO.

</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">You are not comparing apples to apples here. You go on talking about depreceation or market conditions that affect the price on the vehicle, but this is different. We are talking about a large scale manufactiring defect by GM. When I took delivery of my 2001 GMC Sierra, I was running smooth and had no audioble noises. After the 3rd oil change, I started noticing a light ticking after the engine reached its nirmal operating temp. Now at 20,000+ its a loud embarassing knock. Let me ask you something oxidizr. If you were in the used truck market, would you pay fair marked value for my truck after you heard that loud metal to metal knocking. Of course not, and nor would any other rational individual. My truck is probably worth 3-4k < fair market price because of this condition. This is exactly what we are referring to when we speak of financial inconvenience/injury. Evendently, you were blessed with a nonknocker engine and that is great for you but I certainly think you are being a little judgemental to those of with this problem.

Mr. Oxidizr, If you go to the lemon law statutes of your state or most any other, one of the compensable issues is loss of value due to said "Defect". No, not loss of value because it is out of style like a gas guzzler. It will be no problem to get an appraisal of a severe slapper versus a non-slapper and see the difference in price the engine knock defect causes. Keep in mind, we are not talking about the vehicles that have a very light (fuel injector like) tapping on cold start that goes away upon warm-up. We're talking hammering and hammering from these diamond-hard pistons with no skirts might not result in catostrophic engine failure (broken piston or rod through the wall). But, the hammering will cause cylinder bore damage. Not saying all tappers will show it. All hammerers will though. It'll have 200K worth of wear in the spanked cylinder at 50K miles. I know its hard to hear about people putting down your brand of vehicle for a problem you obviously don't have. Don't be naive enough to think that because you don't have it, nobody does. Have a little compassion, guy! http://www.gmpistonslap@cjb.net

Shark_G:

I appologize if you feel that I am judgemental regarding your issue. I am merely reacting to the information as you had stated in your response. Have you had your motor condemed as a "piston slap" knocker? I'm not talking about what you hear emmiting from your vehicle but have you had someone document your issue winthin the ranks og GM or have you sought out a professional diagnostic from a certified mechanic who is willing to condem your motor as defective due to your problem. If you haven't then you may better understand my issue here. MANY, MANY people are hearing the slightest noise and perceiving it as knock due to the profile of this problem. Some have a legitamate issue which require GM's attention and others are simply misunderstandings or misinterpreations.

</font><blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote:</font><hr /><font size="2" face="Verdana, Helvetica, sans-serif">You are not comparing apples to apples here. You go on talking about depreceation or market conditions that affect the price on the vehicle...</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">You may be right...I did use very a broad illustration but my point is really the same. EVERY aspect of resale is a factor of market forces which may or may not be founded in hard facts...personal perception play a large factor in determining "fair market value." I do understand the fact that your claim is derived from your labeling your vehicle as "defective" but this goes back to what I said above, has it been condemed as defective by ANY kind of professional/certified mechanic?

</font><blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote:</font><hr /><font size="2" face="Verdana, Helvetica, sans-serif">We are talking about a large scale manufactiring defect by GM.</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">How Large is the scale of this problem? Are their any offical reportings on the number of GM condemmed motors? Are their any numbers as to how many validated complaints have been made and warranties fullfilled? Are they any people who have had their motor's torn down and inspected to prove the amount of damage incurred? There are too many generalizations being made about the scope/scale of this problem.

</font><blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote:</font><hr /><font size="2" face="Verdana, Helvetica, sans-serif">If you were in the used truck market, would you pay fair marked value for my truck after you heard that loud metal to metal knocking. Of course not, and nor would any other rational individual.</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">To be quite honest with you I haven't heard the problem, so I cannot make a hypothetical response to your description of it. But, if the problem had the "large scale" that you said then most GM vehicles would exhibit the same noise and as such this noise would be considered normal by definition. This is the problem with the issue you are facing. Proving that the noise leads to actual damage beyond simple perceived loss of value is what a court will address. Market perceptions of problems are not facts and as such hold little legal value.

If in fact you have evidence to show your motor is defective have it documented and have suffered actual financial damages then you may have better luck in your pursuit.

Again, I appoligize if I seem rash, blunt, judgemental or unsypathetic to your embarassment but these are my perceptions and opinions regarding this problem.

MR.BigBlackMotor:

In response to you THUMBS DOWN:
I have wondered what your true purpose for being at this site or any other site really is. Here you have registered and posted a whopping six times and guess what they all were about? HMMMMM??
OH yes, all about plugs for your website...did I mention you link to your website EVERY time.

I am capable of understanding that if you felt that you were wronged you would pursue this issue with great zeal, but this site is not your soapbox it belongs to all of us members in a way. We come together here to share information regarding or vehicles both good and bad and sometimes just to shoot the **** with fellow like minded people or at least those with a common intrest in automobiles. I challenge your presence here as being self serving and your remarks as propaganda. I am very suspicious of those whose only purpose is to stir the pot, as you have offered no other remarks nor even entered the lounge to speak to other members on a non-piston slap related issue. So as you continue to post I will continue to respond...with or without your approval.

Who conducted the independant testing? Or might this be another approxomation/interpolation of damage made with your expert opinion?

What's hard to hear is UNSUBSTANTIATED rantings of a problem that does exist but which you insist is happening to everyone. The only one naive is you...for believing that you can simply become a member of our internet community and dispurse your propaganda and serve your purspose without getting any criticizm.

Richard

BTW- For all those who have expirenced this problem, members or not, I am empathetic to your plight but I will not stand by and listen to this soapbox ranter without responding. Should you have the documentation and follow the proper channels you will receive some resolve...I know of many who have so long as their pursuit was genuine and substantiated.

Mr. OXIDIZR, you are incorrect in that I have challenged your right to respond to these threads. This is even though you not are speaking from a position of any knowledge or experience with the issue at hand. Also, the last time I checked, I was a member of this site and have no doubt contributed to the education of other members in various aspects of the problem to your great disdain. Many of us have pursued this through the normal channels and have been given the proverbial "STICK IN THE EYE" by our favorite corporation. Sometimes the truth hurts!

Like Oxidizer said, this site, GMTrucks.com and the other Silverado website have been nothing but a soapbox to peddle your "campaign of dissatisfaction" with GM. Deal with the problem or get rid of the problem I say. Go get rid of it if this piston slap issue is so large a deal to you.

Mine does it, it eventually goes away, and it isn't hurting performance any. So until it does internal damage, which just gives me an excuse to build the motor anyway, I fail to support your cause.

Oh, and I think Oxidizer knows a thing or two around here as he's the one with a 400rwhp supercharged Silverado.

HMMMMMM! Lets see.....More posts makes you more qualified and owning a Whipple makes you an expert on "THE GREAT GM PISTON SLAP FIASCO".

Sounds like I first need to make some more posts. Especially, those shooting down what some poor injured GM consumer (whoever started this thread)has to say when I have no knowledge or experience on the topic. Then, I need to buy a Whipple and that'll make me the expert!...OK!!

If you are tired of hearing about "THE GREAT GM PISTON SLAP FIASCO", stop looking at the threads with "PISTON SLAP" in the topic! I'm sure You and Mr. Oxidizr have some knowledge on some of the other topics.

By the way, there are some of us who wish our engines were right enough to allow mods. An 8.1 owner with a Whipple only would be looking at 500HP.
