i figure your supposed to set the engine on TDC before you start this job and everything turns out fine but if that didnt happen, then what?
guess i can spin the valve gear till both valves are closed on the 1 cylinder but is there a more precise way of getting valve timing correct?
does it even sound like i sorta know what i'm trying to ask here?  |
On the 4.0l it takes a special procedure, and also a special tool to line everything up, this is a cridical procedure if not really mech. inclined probally bent some valves, call me and i will get you the procedure if you want
