1993 Firebird 3.4L
I was driving home from work yesterday afternoon (5 mile commute). I was stopped at a light and I smelled oil burning. Sure enough I looked at the pressure gauge and the oil pressure was about 25 psi. My car always runs at about 40-55 psi. I pulled over into a gas station to check it out. It was clear that the sending unit blew out and the oil was spraying out the back of the unit where the wiring plug goes in. The oil level was down about 3/4 of a quart.
So I filled the oil and drove it home nice and easy. When I got home it was down 1/2 of a quart.
Sending unit was very easy to remove from the top. I went to Advance Auto and bought a new one ($25). When I returned home it was very easy to install it, again from the top. I also bought a can of engine degreaser to clean up the mess all over the left side of the engine bay.
Luckily this happened close to home so it was not a really big deal. New sending unit is working fine, pressure reads 40 at idle and about 55-60 under a load.
