comp cams lifters has killed my engine
for the last 500 miles i have had a godawful ticking sound coming from the
ds bank of my 2000 ws-6,the motor was replaced witha jasper short block
& the heads/cam package is an mti(which by the way uses comp cams)
the cam is a g-1 grind.after running the motor with the stock valvetrain
i was convinced that the tick was the result of a big cam.other people
said that all ls-1 engines sound that way-i knew better all along.i changed the rockers & the sound persisted-i was finally concinced that i had a lifter that was bleeding down(i even knew which cylinder-#5)so i decided to pull the head-wow,wahata suprise.the # 5 intake lifter was mismanufactured.yeah,that 's right.the flat sides of the lifter that are against the plastic tray fit fine,however the roller ballgoes across the lobe-not up & down.they all fit in the cup fine,so they were installed with no problem.comp has been e-mailed the pictures & has seen them-their response was the same as mine.the lifters will be sent off tomorrow to comp for their review.i will post pictures of the lifters & keep all updated after my follow up conversation with comp cams.i can't describe how much of a setback this is-especially for my daily driver-feel free to e-mail me @ supap72@yahoo.com

Good luck on getting them to pay for the motor. There have been several threads debating this from several manufactures and for the most part the response has been we will replace the defective parts which are ours, but as for your motor we made no warranty on that. If a shop installed the parts you might have more luck with them, (maybe) being that should be an obvious problem if you make sense of it all. This is why unless you are running a real radical cam, stock lifters are the way to go. Very seldom do you hear of a stock lifter doing something stupid.

There is no way that would not have been seen when installing the lifters into the plastic retainer.You would have it upside down installing the lifters and looking at the wheels before you put the retainer back in the motor.

Are you sure It wasn't just the wrong lifter.Maybe It was a lifter for a big block chevy GEN VI.(these lifters are made this way) It was probably a packaging error but, it still would have been noticed before putting it into the motor.

I Agree That It Should Have Been Noticed-however I Did Not Put The Motor
Together-i Will Put The New One Together But Saying That It Should Have
Been Noticed Is Like Preaching To The Choir-oh Well,i Can't Change The Past
I Can Only Alter The Future-any Thoughts From Any One About The Metal In
The Oil?i'm Wondering If This Will Be A Probelem Later In Life?
A New Motor Would Be The Way To Go-we'll See.

If it was me I wouldnt have sent them anything unless I had video,pictures and numerous credible witness with their own pics and videos! I hope you did so because what is stopping them from throwing away the bad lifter(s) and or saying you touched up the photos,etc... Im not calling Comp crooked but some companies are very much so!

I think this post was uncalled for. Granted you weren't saying that Comp would do this.

Packaging mistakes do happen. If the installer put these in and did not catch that one of them was a Gen VI lifter, then it is their fault, not comps. That is why you use a professional.
