OT: oil pressure question on 92 GMC 350
 

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.
