style='FONT-FAMILY: "Arial",sans-serif; COLOR: black'>Marty, I experienced low
to no oil pressure at idle on my 4A street car several years ago, and what
fixed it for me was new rod bearings and mostly I think was a close inspection
of the oil pump and maintaining those clearances. So new rotor assembly and a
careful removal of all of the scratches and worn areas of the bottom plate on
the pump where the rotors set. Emery paper and a flat piece of glass and a lot
of hand work getting it flat. I am assuming the oil pump is similar to a 4a pump
in it’s construction. Many highway miles later hot idle is 30 or above and at
3000 rpm it’s been a steady 65 to 70 pounds. Maybe look there if you haven't
already done so.<o:p></o:p></SPAN></P></DIV>

think Peter is right. The GT motor I am about to rebuild had similar symptoms.
Great pressure cold, 75-80, then dropping to 20-25 hot at idle, sometimes less
and I had to keep RPMs up to ensure lubrication. Uppon teardown, I had a a
couple of big end rod bearings showing some copper, and others indicating wear
also, all on the compression stroke side (opposite side of oil journal). Mains
were all OK. I run street Mobil One 15-50, but think I will change after
rebuild.<o:p></o:p></SPAN></P></DIV>

style='FONT-FAMILY: "Helvetica",sans-serif; COLOR: black'>I could use some
opinions. Some history. Spitfire small journal 1296 engine, rebuilt 6 race
weekends ago included all new bearings. I tore it down this spring to check it
over prior to last weekend PVGP event. Cam and crank end floats were to spec.
Rod and main bearings checked between .002 and .003 clearance. I do not have the
actual numbers in front of me at the present. Cam bearings appeared to have some
slight visual wear at the bottoms but I did not actually measure them. I run
Brad Pen 20W50. Oil temps run 210 and water temps run 190. EGT are 1200/1250
range on track. I was fighting low oil pressure at running temps all weekend.
Once my oil temps come up on track the pressure drops down to 35psi. If I add
enough springs to the pressure relief valve I see over 125 psi cold so I am
thinking my pump is putting out enough pressure. I tried shimming to get 50/60
cold at idle and it drops to 35 at operating temps at 7000 rpm. I tried a new
pressure gage over the weekend and the numbers did not change. I am currently
running an auxiliary oil line to the head, I removed it at one point over the
weekend and it had no effect. I tried a new pressure relief valve assy and it
had no effect. I believe this situation actually started a season ago
because I added a washer to the pressure relief valve last season. I’m
thinking it most likely is cam bearing wear even though all the bearings were
fresh 6 events ago. Any guidance? One thing I did learn this weekend is my
accusump pressure gage is incorrect. It was reading about 30 psi higher
that my dash gage. I was thinking it was probably correct and my dash gage was
wrong until I replaced my electric dash gage with a mechanical gage and its
reading matched the gage I just disconnected. Oil pressure readings are taken at
the port below the distributer. <o:p></o:p></SPAN></P></DIV>
