Re: Comp cams may have ruined my engine(pics)

Now the grey area is that you said that you paid to have a mechanic install right? If you did, there is no reason why he couldnt tell the difference between an NSA rocker and an aligning one. If there's no guideplates, he should wonder what keeps the rocker centered...even if you supplied the part, he should check for compatability, that is why you paid for his expertise.
Yea I agree, expertise is what the mechanic missed. I'm sure the ppl who deal with comp on a regular basis, know enough that comp messes up orders all the time. I would have checked but I had no reason to think that brand new rr's could cause my perfectly good 60,000 mile engine to blow up, cease, and trash every single new part I just put on the car. How many people here would actually check all 16 rr's for a miniscule variation from sa to nsa? I looked at both rockers for 2 minutes and it still had to be pointed out to me. So I guess me and all these people should not be modding our cars because we don't know what were doing.

I think It's up to COMP to check there sh*t b4 I get it ECSPECIALLY parts that can f**k up an entire engine.

I agree. We own a family concrete business and if we send out a product and it fails we have to pay to tear it out and repair it. We can't just say you should of tested the concrete when it came out. It's just Comp trying to get out of responsibility. I can see them not being responsible for parts that fail that are being turned 7-8000+ RPMs in extreme environments but this is an error on their part.

Re: Comp cams may have ruined my engine(pics)

Now that i'm done ranting....Would it be possible that there was no damage when the valve dropped. The mechanic had to buy a new keeper, have no idea where he got it. Maybe he got the wrong size and it let the valve go while driving. Can u mess that up? Just trying to rule that out. If it was caused by a piece of metal in between p/v, there should be gouges in the cylinder wall correct? I'll go check it out tomorrow, and also try to find that nsa rocker.

edit: he also put on a stock rocker stud which appears to be a little shorter than the rest. Would that matter?

I think you're loony. You should do the research and know what you are ordering before you buy it.

Not a good analogy. Don't tell me that if a customer supplied the product and it was wrong/defective you would re-do the job? That would be unusual, though different fields differ and I don't know squat about concrete. I'll bet thoguh that you would be leary of taking on a job like that and would try to discourage the customer if not refuse.

In my "real" job we almost never use customer supplied "materials". If you don't have control over the materials, how can you be responsible for the end result? At best, it's a gray area and best avoided. At the shop, we discourage customers from supplying their own parts and have them sign a special waiver when they do. Approximately 1/2 the time when the customer supplies the parts there is some problem - sometimes minor, sometimes major. When having your car worked on, let the shop supply the parts. That way they are responsible for the result, no confusion. If you are doing the work yourself, you must check all of the parts to be sure they are correct, free of visible defects, etc.

It has been recognized for a long time that in case of a defect, the manfacturer of a part is not responsible for "consequential" damages. I am sure their warranty will say this. Fair? Maybe not. But that is the way it is so you better get used to it. It's a risk you take working on your own car. At the shop, when we do a job and supply all the parts, we are responsible if a part breaks and wrecks the whole thing. Keeps us on our toes, as a couple of these a year can turn a profit into a loss. We can get a new part from the supplier of the failed part, no porblem. But the rest is "on us". If you chose to DIY to save money, be sure it's "done right", or whatever than you assume the risk.

I know how much a broke motor hurts and I am not trying to rub salt in the wounds, just trying to explain the facts of life. Comp makes a good prooduct but they are (in)famous for mismatches. We use a lot of their stuff and ALWAYS check it.

Re: Comp cams may have ruined my engine(pics)

SuperDavez28, IMO your ranting should be directed at the guy who did the install. I don't think I'd have him try to fix things any more. I'm sorry you had such a bad problem, but I don't agree with this part:

I can't really blame the mech for putting the NSA rocker on as the difference between the 2 is so small.
Now that i'm done ranting....Would it be possible that there was no damage when the valve dropped. The mechanic had to buy a new keeper, have no idea where he got it. Maybe he got the wrong size and it let the valve go while driving. Can u mess that up? Just trying to rule that out.

I agree with Rich and others that it is the customer and/or engine assembler ('engine builder' is too generous a term for someone who missed a NSA rocker on an engine without guide plates) who has the responsibility to inspect the parts before they install them. If the mechanic had trouble telling SA from NSA rockers, he was a parts changer and has no business working on a modified engine.

A lot of the stuff that cam companies sell they do not manufacture in-house. They purchase the parts already packaged from vendors. Some companies may package in-house. While that may allow them to better control what gets into what package, it's often more costly than having someone else package them.

For example, they might have a packaging company pack all of their parts which they make and/or buy and ship to the packager. This company can package very inexpensively, so our retail cost is lower. The problem is that the folks loading the parts or loading the packaging machines with parts aren't necessarily gearheads, and couldn't tell a SA rocker from a NSA rocker even with instructions. They can tell blue painted springs from red painted ones (unless they are colorblind) so you have a better chance of getting springs of the same color.

Should Comp include a disclaimer/instruction to the end user to check to see if each part is what it should be and include a 800 number to call if a part is mislabelled or mispacked? Sure, but who reads that kind of stuff? Certainly not the mechanic who would install an NSA in an SA application. Most folks only call when something fails, not before. The real engine builder checks the parts anyway so its not for him.

Packaging errors are a consequence of price competition. I'd much rather have a packaging error due to cost reduction than inferior machining or inferior material.

The manufacturer's responsibility is the same whether the wrong part was installed and failed or found prior to installation: replacement of the part. If I were the manufacturer, and a customer called saying he found one NSA mixed in with the SAs, I'd speed him a replacement and a pickup tag to return the wrong, but not yet installed part. Happier customer and I can resell the unused part.

I said if we supply the wrong product and it fails we have to pay to replace everything, and its happened before too. Its about being responsible for your actions.

Got it. So we are really agreeing? IF you are doing the whole job. you are responsible for the whole job. If the customer supplies parts/materials or labor, it is kind of a gray area. And like I said, in my real job (medicine) we absolutely try to avoid this. Sometimes a patient is on a medication or uses a device we are not familiar with, do not stock, or whatever. In that case, they use their own but we have them sign a waiver which indicates that we cannot vouch for what they have supplied.

nm, i don't care to explain it. If you ask me the company needs to be responsible for their own actions.

Re: Comp cams may have ruined my engine(pics)

It sucks man as I just rebuilt my motor 2 times this past summer to present. It might get to run a gain tomorrow. Fortunately the machine shop who did my work was fair about the my problem which took out my crank and had to bore it .030. My dad and I built the motor. He has been working on cars, semi's and building motors his whole life (approx 40 years). So he is qualified. The machine shop asked to tear down the motor after I got it out again. The machine shop couldn't find anything we did wrong in building the motor. We were exceptionally clean. The shop couldn't prove we did wrong, and we couldn't prove they did wrong. The machine shop gave us a break and sold us parts a jobbers cost, and paid for most of the machine work. But we were extremely calm with them and always very polite. They didn't have to do anything. They said if they would have built the long block then they would be 100% responsible. But we built it and got a great break. Your case is a bit different, you were given a bad part that you're right should have been checked. Have all of you paper work and any proo in a row and good luck. Now is not the time to be an *******. I'm not saying how you are, but I understand how you feel.

Good luck:

ZMAN

Good luck with that....

The Comp R's are failing in various instances, but the rocker arms are not. Reread OldSStrokers post, it's not a mechanical failure that caused his issue but someone not knowing what to look for or that something is wrong. You have to inspect the parts before you install them, I've had parts from many compaies that were mislabeled in the box or the wrong part, I don't have a issue I just send them back and get a new set.
