The clearance makes NO difference to the timing. The only crucial thing is that there is enough preload to stop the plunger from hitting the snap ring; if it does this it will destroy the lifter quite quickly.



As above. The clearance is not at all critical for hydraulic lifters. They automatically adjust themselves to zero clearance every time they pass over the cam base circle; it is not the same as setting tappet clearances for solid lifters.

Hi Myles,

Thanks for the well explained replies to my questions, I suppose my next question is, is there any point in using adjustable pushrods with hydraulic lifters or are they just ment for solid lifters?

Cheers,

Pete
