ive searched this topic with a couple questions to be answered only finding threads about "ticking" and other varius related topics. none really pertaining to answer my questions.


question one: sounds dumb but, with the HLA's bled and installed in the head with the rest of the top end parts including the valve cover, i should no longer turn the motor on the engine stand....correct?

question two: the FSM refers to bleeding the HLA's with a thin "push rod" tapping the "check ball" to bleed the air out. i could not seem to feel or push anything like a check ball in the HLA to bleed air. what did happen though was when i inserted the push rod air bubbled out. i moved the push rod up and down untill the air stopped bubbling. so is the HLA bled now? or is there still air inside the HLA and i do need to find that "check ball?" maybe my push rod is not thin enough? i am using a metal coat hanger.

if this does not make sense, i will try to explain differently. anyone actually dealing with this should understand though....i would think :rolleyes:

kind of a new developement in the last 5 minutes. i went back to the HLA and tried again. seem to have found a point that i can push it, and no air comes out, but all the old nasty murky oil is coming out. i would assume this means it is bled.

its like when i push, the top part of the HLA moves down, and the old oil squirts up and out. only thing is, 2 of 8 arent doing this. so in lies another question.

When I have bled them in the past I bled them until all of the air and old oil crap was out of them. Sounds like your nearly there. As long as you can push them up and down in the oil they should be fine.

hmm, 6 of 8 move up and down. 2 do not. i can push on something in those two. something inside moves, but the "top half" does not move. stuck? gritty?

the circled part is the part that moves (top half), horrible pic...sorry
