Lunati Retrofit Hydraulic Roller

You should if things are good and tight in the lifter... but I think the other poster was talking about bleeding oil pressure from the rest of the system by exposing the lifter band, not bleeding off the lifter itself.
Got it,I misunderstood.
I have a set of Comp rollers that bleed off when the engine is hot at rest in a very short amount of time. Cheap crap, I have leaned a hard and expensive lesson.
