I have a rebuilt 2.5 that will not oil on the number 2 lifter. Have changer lifter and pushrods. I think something is stopped up. Motor run about 500 miles before this problem. Need some help. Have tried everything but flushing the motor. Has 50lb oil pressure but pull valve cover and that lifter and rocker arm are dry. Sounds bad because lifter not working.
I to have never rebuilt a 2.5, but there should be an oil port drilled all the way through the block from front to back in the line of the lifters, pipe plugs with alien socket head in each end.
pull all the lifters and rod it out, or if you can reach down in side that lifter hole with a wire to clean ports on both sides.
I hope that was all that was wrong is the rebuild but I have never run in to this before. First jeep I have worked on. I have built ford and dodge motors and never had a problem. I did not build this one and was helping a friend and it had me clueless. Never built a four banger but now I no a lot more about them. Thanks
