due to some.. um.. fuel injection errors while repairing my car, my crankcase was filled with fuel, and some carbon. i strained the fuel i pulled out and sliced the filter, and it contained no metal.
i drained the fuel/oil mix out, put in fresh oil with some ATF, ran it to temperature, and drained it again. the oil is now golden and perfect.
this is a recently refreshed engine, rings, bearings, etc. engine runs well; no weird knocks or anything. the compression is good..
the oil pressure, at idle, is perfect. i've had a bunch of LT1s. the gauge reads 1/3rd at cold idle, drops to just above 1/4 at hot idle.
weird thing is, no amount of rpm will increase that oil pressure. whatever the oil pressure is at idle, it's still there at 4000 rpm. it doesnt drop, it doesnt fluctuate... its just.. there.
i put a mechanical gauge on it twice. the first time, i blipped the throttle, and pressure went up, so i figured.. ok, it's the sender. drove around for a bit.
i just bought a sender, but because they're such a bitch to put in, i figured i'd put the mechanical gauge on it again.. and i blipped the throttle, nothing
the oil pressure stays 100% constant at all rpms
what would cause something like this? bypass stuck open maybe? how does an oil pump bypass work?
