i recently replaced heads on my 1990 2dr exp ,both heads had small cracks.
bought two used heads maged and had valves ground put the heads back on
runs great. my problem is now when it gets warm the lifters are noisy. 2.9s
were adjustable rockers on 4.0 are not so i cant adjust valves. my oil pressure
is 35 lbs at idle, and with valve cover off getting plenty of oil up top on rockers. i tryed adding stp oil treatment made it worse beleave it or not!
im not sure if valve stems were ground to short or lifters are just warn out.
i can turn push rods when cam is down ?
im stumped on what to try next any help appreciated
thanks
