Well I just fixed the coil issue and got the newly
rebuilt engine running. It sounded good until one
cylinder began misfiring. I came to find out that
the #3 cylinder push rod adjustments had backed
off and the valves weren't opening. So the
machinist must have forgotten to tighten them all
the way or something (which now causes me to doubt
his abilities but he has 40 years experience and
does this all the time soooo.... anyway..) So now
it runs and sounds great! but I have no oil
pressure at idle. It goes up to 30-40psi when I
rev it up, but its only about 5psi when its idling
(if that). I read a few posts on here about low
oil pressure, but would anyone like to offer a
list of items to check systematically? I checked
the gauge and that works fine. Im going to check
the 90 degree elbow that comes off the side of the
block. I also should note that I put a screw on
oil filter adapter on that was not on the old
engine. It uses the same mounting flange on the
side of the engine but it has an adapter on top,
Could this be causing an issue? Also just FYI I'm running straight 30 weight oil and there's no knocking but I took the oil capillary off and it just dribbled lightly while the engine was idling, so Im pretty certain I have low oil pressure. The oil pump was also pretty new before the rebuild but the machinist said he inspected it before re-installing it. Of course Im second guessing everything he says so Im not ruling it out, but it was fairly new before the rebuild. Anyway any advice is
better then tearing the engine out, so feel free
to share ideas and ask questions. I plan to attack
this in the morning.
