One of our Dixielanders at Calhoun rally drove in with no issues except shift cable froze up. We got it freed up and back on the next day and started it to check and the engine puked 3 qts out before we could shut it off. Coming out from oil filter base. Found it loose, tightened it up and started it again, puked out 3 more qts. Replaced the gasket with a new one and did not leak till the next morning when he started to leave and it had a leak. Removed the oil filter and replaced with new oil filter and tightened with wrench and saw no leaks. All seemed good till he started to leave Sunday and found the dash oil pressure gauge was pegged on high and the manual tube gauge was pegged on 80lb. He said both gauges were acting normal on the trip down with ~ 45 lb. Since both were acting wacky and the oil blowing out previously he decided to call AAA and haul it home. He contacted me and said he bought a new 100 lb manual oil pressure gauge and installed at front of engine in oil pressure sending unit port and when He started it, it pegged at 100 lb. I`m thinkin the oil pump relief valve is stuck closed?? I have heard of them getting crud and no oil pressure at idle but never heard of it sticking closed and building over 100 lb of pressure. If the cooler, lines, filter, or bypass valve was clogged the oil pump still should not build 100 lb cause of the relief valve. I would think if a passage was clogged it would not register 100 lb at front of engine?? Anybody got any Idears except digging the oil pump out??? Is there anyway the bypass valve could cause this???
