I just performed a compression test on my baby and it was very low on all 4 cylinders (under 150 for all 4) standard is around 179 IIRC. I proceeded to pour a capful of oil into each cylinder then retest each one. the readings i got were about 200-210 a cylinder. So from this i assume that my rings are bad! the engine has 115k on her and i never take her up into the high rpms or bash on her at all. so my question is, how easy is it to replace the rings? Could i do it myself? I have done my brakes and vlsd, just wanted to know if it was feasible at all to undergo it myself! Does anyone have any ideas or advice for me? thanks in advance. Logan

do a complete engine overhaul, you will have to tear it down to do the rings so you might as well do it all.

verify the results with a new one or pour oil in the compression gauge, maybe it needs a ring job!:pface
