My engine was making a knocking noise so I thought it may be a bad lifter. I pull my drivers side head off and found this. Only 1,500 miles on these! I want my money back!

 

i feel you pain bro. i just had 4 of my type r's come apart. and 4 of the 12 that were still together have cracked retainers.

 

I had a set of Comp-R lifters wherein one of them failed the same way...on the road course at Lime Rock Park. I brought it home with a wee bit of extra valvetrain noise but no driveability issues, found the two pieces of that cheap stamped-steel retainer plate stuck to my oil pan drain plug magnet.

I sent the set back to Comp, then sold the new replacement set they sent me. From thence I have a strict no Comp lifter policy.

 

Im going to send this set back and sell it. At least it will replace some of the money I had to spend on new gaskets and lifters. Damn im glad I can do this stuff on my own, this would have cost a furtune.

 

o man i just put these in my car you guys got me scared now! lol

 

I just bought some LS7's to replace these. Only $100.
