check the lifters for a kind of film on the sides.
the film can make the lifters sticky

You're in this far JJ . . . The best thing I did to wake up the 4.0 in my Comanche was to change the cam, I put a comp cam in mine (can't remember the grind # right now) but that made a big difference in my HO. The only other mods were better cat muffler and tailpipe and a K&N in the original air box and my Comanche rips pretty good with an auto trans and 4.10s with 33s

Was going to pick up another motor in the new year and slightly build-up and refresh.Cause this motor blows alittle blue and was ticking:dontknow: :D

Was hoping to leave as is till then but will get this one going again cheap as I can(lifters,pushrods and see what I need for rockers and fulcrums)but just get back running again for now

your exhaust manifold, if your not gonna replace it with a new custom one i'd just weld that one up cause if you use a another stock manifold it'll just crack there too. every engine that i've pulled out all had cracks on there exhuast manifold

check the crank for damage.. thats what happened to my jeep when the lifter fell, and stoped pumping oil.. funny noises came soon after.

oh well a good excuse for a 4.7 stroker![cheers] [cheers]
