I recently replaced the gaskets on the water pump and timing chain cover on my 1992 Ford F150 5.0 L 4x4 (140,000 miles). Now, the oil pressure gauge drops to low at idle (anything less tha 10000 rpms) when the truck is warmed up. I did an oil change and the problem still exists.
Could it be the sending unit? Oil Pump?
have the same problem?
