Why would you post this and not provide more details like the Same location.

To be fair, he did. 2nd and 3rd sentences:

This is my 4th set going into this engine and the lifter that fails is ALWAYS the same one. The funny thing is that almost everyone of my customers who have had the same failure is in the exact same location as all of mine!!!

I'm with Simon though.. that points not to a lifter defect but some other root cause. If the lifters were defective we'd see failures in varying locations, IMO.

Really? Always the same one? This is no indication of the cylinder number or which lifter on that cylinder. Geesh.

Not arguing with you; I thought it was easy enough to follow that "always the same one" indicated the same location is failing each time he replaces the lifters. In his other post ("Lifter stuck in bore") he mentions it's #5 cylinder but not specifically which lifter.

I mean remember the stalling issue caused by the sticking vent valve in the fuel tank that they extended the warranty on the fuel tank indefinitely? And that failure was miniscule compared to the lifter failures! How do you think that was started?

Wild-assed guess: enough complaints to the NHTSA got them looking into it, and the warranty extended on the fuel tanks, because it's literally a safety issue. Cars were stalling while moving in traffic.

If it's not then why do LS/LQ engines NOT have this same issue yet they run roller lifters?

I guess you don't know much about LS engine lifter failures, then. There's plenty..

Really? Huh, after working at Parkway Chevrolet in Tomball for almost 4 years I didn't see one. Plenty of crank and cam failures caused by unfiltered oil due to GM's POS oil life reminder system causing oil filters to clog and bypass.

You've convinced me, then! Those lifter failures must be imaginary.

By the way what's an LS/LQ engine? The family of engines is known as LS. That includes LQ4, LQ9, etc. You'd think someone that worked for a Chevy dealer would know that.

LS is an aluminum block with iron sleeves.
LQ is an iron block.

So the super common LM7 5.3 is an LQ engine? How about an LY6? etc. Do you realize the performance LSX engine is an iron block? You can call the iron block LS's an LQ if you like, but that doesn't make it so. I mean.. GM doesn't even call them that. I'm gonna bow out now as I can see what I'm dealing with here and there's no benefit to further debate.. you believe what you please.

Hey, I fixed my lifters once. You said you did yours what, three times now? And now your engine is broken? Again. Perhaps with all of your claimed experience and contacts we would think you would not have so many issues. Yetbhere we are! Maybe you ought put yourself in that bashing thread?

If I were a photoshop artist, and I'm not, I would have that sword being drawn out of a bucket of failed lifters.
