Whats inside a hydraulic lifter

[OX1]

Is there an o-ring type seal (or any seal) or are all the small black pieces just junk from my engine? (my guess is junk as lifter is new and pieces are too hard to seem like a ground of seal).

I am not aware of any rubber seals in a hydraulic lifter. Is this a new motor? Where are you finding these black pieces at?

If you are finding small, black pieces of plastic in the oil pan of an old motor, it's more than likely pieces from the original, plastic-coated timing gear on the cam. Time to get a new timing gear set:-X

It's an old motor with a new comp cam. Called comp and they said there are no seals. Suggested maybe parts of an old valve stem seal. Must be 20 or so small black pieces in the bottom of the lifter (inside), odd that so many of them could get in there so quick (maybe 5 hours total on this cam). I ordered a new lifter, hope that fixes it.

What part of the engine are you calling "bottom of the lifter"?

Chances are you have alot of crap floating around in and old engine, when you do a cam swap ect you loosen it up and it will end up in places like the lifter ect and live there forever. There is not supposed to be rubber or plastic in the lifters.

Thanks all. Must have been the ball check valve stuck open from junk in there, as the oil stream coming out of the pushrod was full flow (would have shot 5 feet past the side of my bronc if the defelctor was not there) vs the normal dribbling you usually see.
