Now i'm confused...to double check what I did...please let me know if I did
it wrong...I brought each cylinder to top dead center...I adjusted the
valves that had the piston at top dead center. Ensuring the lifter was not
collasped and the push rod centered I took 1 1/2 turns versus 2 like the
bently states. Now after I did this the car missed and at start up it seemed
to have no compression until the lifters started doing there thing. I will
follow up with a compression check. Is this right or wrong... I am referring
to hydraulics.
