Comp lifters

Look what I found today. Funny thing is, there are 17 needle bearings that make up a comp roller lifter. Not ONE inside the engine. Hmmmmm.... Guess that's why you shouldn't buy used engines!

well that dont look good.....

No sir, the worst part is the bouncing around of the roller tip scored the cylinder walls up pretty deep. I think the block is trash.

Comp lifters and LARGE rollers scare me alot lately

how many runs on um?

so....you think somebody got the bearings out before you bought the motor?

Ding Ding! We have a winner!

I suspect there are 17,000 pieces of needles inside the engine.

Ground to a powder in the bottom of the pan.

ground to a pulp....... thats a hell of a thing to pull the lifters out and remove the needle bearings..........

Most likely in the oil filter.

I found a roller lifter needle bearing stuck in the base oil pump gears in a 6.0 yesterday........ I bet it costs more to fix........

Lem, I hope you are right (And I need parts by the way, call you Monday), the guy I bought the engine from seems like a truely good guy. The problem was when I bought the engine from him, I pulled the pan and there was a needle bearing on the pick up. He had an issue with some previous roller rockers that spit out needle bearings, had Jet Boat Bob go through it and freshen. He said it must have been a bearing that wasn't caught in the clean up hidden some where which made sense but when this happened I became very suspcious. But if you are telling me that all those needle bearings can be chewed up into small particles, that makes me feel much better and feel bad about my assumptions.

These lifters were never exposed to a large roller cam.

And unfortunately never will, but I suspect the next set will be

seen 3 different motors this year with the same problem ( all fords)with the lifters and all comp cams lifters all with less than 70 runs on the lifters and one only had 25 passes !! the needles turn to dust!!

I always use these types of things as an excuse to go bigger and badder........

Another funny thing is I met a feller that browses this site a few weeks ago at a track in South Carolina and he was talking about all the bad things he has heard about Comp lifters...

Yes Jon you are right! Lem has been saying this thing wants pistons and a real camshaft so I guess here we go!

boogity boogity.........

Guess I need to step it up anyway so I can come play with y'all at the next bash.

Think that "green oil" would prevent this?

17,000 1/4 mile passes at least with pro comp lifters and green oil.
