Hey all, thanks for all your help with my starter/solenoid. Now I got a new one for you.
This has been a consistent theme since I have owned the engine. I have an early model A4 that is pretty basic. I have new oil pressure sending unit and a new gauge.
When I start engine and "cruise" at roughly 2000 RPMs I get good oil pressure, about 40PSI. My engine temp holds steady at 130F. Over the course of an hour cruising, my oil pressure will drop to abot 20PSI and hold there. I use 40 weight (its all i can find in the bahamas). I have tried tightening the oil pressure needle a turn, and then another, and still no change. It does HOLD at 20 PSI though.
I check for a leak at the gauge, the pipe, nothing. I get that the oil thins out as it heats up, but a loss of 20PSI?? Any other thoughts or suggestions?
Also, I change my oil very regularly. about once every 30 hours. I know that sounds like overkill, but what the heck. IF After about an hour of motoring, when I let the oil cool, the oil will be black. Don mentioned possible gas in the oil, but I dont smell gas.
ANy thoughts on either would be great. Thanks!
