Hey guys, I've been having a few hick-ups with my recent turbo build. I have about 800 miles on it since the rebuild and decided to do a compression test to make sure everything is seating well. I have almost no compression(40 psi) on cylinder #4 and very low on all others(cheap H.F. gauge might be wrong). the engine seems to run ok but the turbo might hide the problem. When I installed the lifters I cleaned, bled, and filled with diesel as per instructions found somewhere on the forum. They were extended and not compressible when installed. The haynes manual showed bleeding the lifter thru the rocker with a small pin but my rockers don't have a hole to bleed them. I was hoping that they would have slowly leaked down on their own, but this might not have happened and the valves might not be closing completely. The njv head and rockers maybe are off a forklift or something. They came with the starion donor engine and looked newish and uncracked, but had really crappy castings without id marks

Should I remove the lifters and bleed them compressed and reinstall?
