Recently the oil pressure gauge in my 92 GMC (350 efi) has been acting up, or the oil pressure itself has been acting up. Here is what's happening:
After driving for a length of time (30 mins or greater) the oil pressure gauge will fluctuate. If the gauge reads low when I stop and turn the engine off you can smell a hot smell, if the gauge reads hi or even normal when its turned off there is no smell.
Where and how would I go about testing the actual oil pressure. ???
TIA Snow...
Ha! I can answer a GM question(only worked on 'em for 20 years so far). The oil pressure sender is on the back of the block next to the distributor. Remove the sender and screw a manual gauge in it's place. Might check and see if the sender's leaking first...if so you wouldn't have to worry about the manual gauge test.
