lifter question

[offshore24]

Took a couple of hydraulic lifters apart to clean. Do they need to be filled with oil before assembly or will pre lubing the engine fill them?

[searaycer]

pump up by hand before going in the engine.

[insanity]

Pre-lubing will pump them up too.

not sure if I'm doing it right but I put oil in them the tried to assemble. They wouldn't compress to get the clip in.

I always put the priming tool in place of the distributor and prime the engine with the drill.

I do that, but is it enough if the lifters have been apart and are empty?

drain the lifter...

get a spray bomb full size cap, fill it with light motor oil

assemble the lifter and submerge it in the cup

bubbles will appear for a few minutes

carefully take a #2 phillips screwdriver and pulse the lifter plunger several times to prime it, don't get it rock hard, just prime it

install and adjust to spec's, and pre-oil the engine

it'll be fine
