    Priming lifters properly

    Guest-only advertisement. Register or Log In now!
    Just picked a new bare head, the guy at the machine shop tells me I have to use a "priming canister" to properly prime and bleed the new lifters. If I don't then the lifters are going to come apart and destroy my motor!? I checked with best friend Google, and I can't even find a reference to this elusive canister. I'm thinking its kinda BS seeing how we've been doing by the book this whole time. Any thoughts?

    The hydraulic lifter?
    They empty themselves when you shut down the engine, and they are filled when the oil pump is working again...

    According to my Haynes manual you are to allow lifters a half hour to bleed down before starting engine after putting them in. As if you could install everything fast enough for it to be a problem

    It's really very simple.

    to bleed out a hydraulic lifter, you simply submerse it in oil and pump the lifter with a rod until it becomes hard to pump, then you know the air has been expelled from the lifter.

    no special container is needed. a red solo cup works perfect.
