Oil Level Sender Diagnosis???
I noticed that oil is leaking from the oil level sender in the past few days. To confirm that, I wiped the entire area dry & clean.
But now, my oil level gauge simply stop working. I suspect while cleaning it, I might have loosen a wire, broke a wire or simply cause enough disturbance for the marginal sender to stop working. But... how could I verify that its dead? The more important question - I need the car for next week on the track. I can live without the gauge, and because of time, I simply picked up a gasket from the local dealer. So the question is: if I simply replace the gasket, will it at least stop the leak? thanks...

Depends on the mode of failure. can you take a pix?

The gasket is easy and cheap to fix. The wiring/connections at the sender may be seriously fouled by the leakage . . .

Patrick,
The oil level sender leak should be fixed by your new gasket. I'm not sure but the oil level sender might be able to be checked out with a continuity tester or an ohm meter. You might want to check out the connections downstream (upstream) of the oil tank. There are a couple of male/female connections that might have corroded or disconnected. Your car isn't that old but you never know. Regards, Rick Ps. still putting the car back together. Body work is done but mechanicals/electricals re-assembly is taking time. Too much travel right now.

Patrick,
You may have bumped and broke one of the two sender wires at the crimp ... under the insulation! There isn't anything you did that could make the sender fail ... You can test the oil level sender circuit fairly easily. Pull off the two Faston connectors ... and short them together with the ignition switch on. You should see a stable 'low' reading on the gauge. If not ... at least one of the wires is open ... a steady pull on the Faston connector should reveal which wire is broken under the insulation! Replace the Faston connector, and test again. If still no joy, replace the other Faston connector. A 200 Ohm - 500 Ohm potentiometer can be substituted for the sender and used to sweep the gauge full range. The new gasket should fix the oil leak, but be very careful when removing the sender from the tank!!!
