are these lifters bad?

[pj91gsx]

I just took the lifters out of a head with 167,000 miles. the top of about 5 of the lifters move loosely up and down. The rest of the lifters dont move up and down at all. Are the 5 lifters bad?

did you take off the head because you thought the lifters were bad? Or because you heard lifter noise? I personally would bleed them and put them back in. Or if you have the money might as well buy new ones since there off.

If you can just pull up on the top of those lifters and they go down by their self they are bad. You should feel pressure when pushing down on good lifters. Just go by the vfaq for the good ones and find five new ones.

ok. they have problems then

how do you bleed them? this head came from a motor that lost compression, i think because it ran rich for a long time because my friend installed a 255 hp but not a afpr. My friend gave me the head as payment for helping him swap in a motor with 73,000 miles.

This is the vfaq I was referring to. http://vfaq.com/mods/lifters.html

the fact that your lifters can be pressed by hand is not telling that they are bad. It tells that they are not pressurized with oil enough to do their job. I bought a set of new ones with big orifaces a few years ago and some were like this when i received them. but they are working correctly .. it just take a time to a lifter to get filled with the engine oil pressure

If there is no pressure at all they are bad. The lifters will still have pressure with no oil in them. He is saying if you shook the lifter the top would move by itself. This is not a good lifter.

in that case yes you are right

i didnt exactly say that but, your probably right. The top probably would move if I shook the lifter. These lifters are pretty pressureless. do you think this is fixable and could this be why my friend car wouldnt crank, because the valves wouldnt come up to seal. The shop that checked the motor said it did bad in a compression test.
