I just recently joined this group in hopes that someone might be able
to help me out with a big problem I am having.
I own a 1976 Camaro RS, 350 with a 4-barrel Quad. I recently had the
engine rebuilt, only has start time and less than 50 miles on it from
puttering up and down my street with it. Just yesterday I noticed
that at idle with the engine fully warmed up my oil pressure light on
the dash was flickering. I immediately shut it down and went down to
the auto parts store and bought a mechanical oil pressure gauge.
With the mechanical gauge installed, pressure on startup (cold)
looked OK at around 55-60 psi. Once she started to warm up though it
really started to drop. Fully warmed up, the gauge registered about
8psi in neutral or park, and about 5psi idling in gear. Needless to
say, I am very concerned about this.
One thing I did notice, the line going to my mechanical oil pressure
gauge (semi-transparent white color) has oil in it as it should, but
there also seems to be air in the line, as I can see gaps of white in
the otherwise black line. Air in the oil?
I have checked the oil level, and it is fine. I have not yet pulled
the oil pan and checked the pump or it's screen.. I have a feeling
that will be next though. I'm praying that this doesn't end up being
a case of the engine rebuilder throwing an undersize cam in with
standard bearings or something of that nature. Any suggestions or
advice is greatly appreciated! Thanks in advance ---
