Bleeding Hydraulic Lifters While Still in the Head - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Does anyone know if hydraulic lifter can be bled inside the head? The head is out of the engine bay and sitting in my kitchen. I have 3 out of 8 lifters pulled out of the head but the other 5 are impossible. The method I have tried that I think is most effective is using a vice grip with a piece of cloth around the lifter. Then wiggling the lifter back and forth while pulling and the same time.

This is on a s14 SR head that has pretty low miles on it. I believe the head has sat out in a garage for about a year or so. My other idea is to use a air compressor and blast about 100 psi into that lifter oil hole and see if it will budge. Has anyone tried this before?

I also saw this forum when I was on google: http://forums.evolutionm.net/evo-how...r-lifters.html
But nowhere in the thread do I see the reasoning behind why he did it this way. It just doesn't make sense to me why you want to push all the oil out of the lifter. If someone agrees with this process, I should be able to flip the head over and bleed them this way.

NOTE: you can tell me to go back and yank on those lifters all you want but the fact is they won't come out. I would rather just leave then in there and hope they bleed out themselves rather than break one in the head.

I wonder why they wont come out. The ones on my s13 head came right out no problem. May if you can find a way of compressing them in the head that might work. But im not real familiar with bleeding the lifters i had a guy build the head for me.

Yea I built a s13 sr head before myself and the lifters basically just fell out. If I were to bet, I think the fact that the head has been sitting out for a while has a lot to do with it.

Yah take them ut first bro.... do it right the first time and don't have to go back and do it another time when you are firing up the motor....

I've seen them bled with them still in the head along with the cams, it was on Drift Tengoku dvd... sorry cant remember which one. He used two lever type things and something to open the check valve inside

you need to sacrifice a Honda for the drift gods to release their precious valve nuggets to you.

just find a nearby volcano and push one in.
