Hello,
I am new to this forum and I am hoping that someone can help diagnose the source of a problem that I am having with my bone stock '63 327/340 roadster. This afternoon I just finished installing a new engine wiring harness and a new dash wiring harness. Everything went smoothly except now the mechanical oil pressure gauge is reading way too high. Prior to disassembly of the dash the oil pressure gauge would read approximately 18-20 psi at idle and appx. 40-45 psi while cruising. Now the gauge reads 30psi at idle and 60+psi while cruising. Absolutely nothing was done to either the engine or the gauge. I could see how a new high volume oil pump might give these symptoms, but as the engine was left absolutely untouched I assume that the problem lies with either the gauge itself or the line. Any ideas?
