Help LT1 Engine Leaking oil at sensor above drain plug
Hello,
I have a 1990 mint low mileage roadster and this question has nothing to
do with it. I also own a 1995 Buick Roadmaster (The Roadwarrior) that
has a LT1 engine. It has 54K miles on it and the sensor that is located
above the drain plug in the pan has started to leak. I have no clue as to
what this transducer does, but I assume it has something to do with
the oil level. Anyway it is beginning to leak and I wanted to know if
it can be removed and resealed or replaced without removing the plan?
Thanks for any help that may be out there.

It's the oil level sensor. I think there is a O-ring type seal on it. I replaced mine on the 95 after I broke it removing the pan. A new one is only around $20.

Thanks for the response. Do you know if it threads into the pan,
or do you have to remove the pan to get to the back side?
Thanks

It threads into the pan. The hardest part is disconnecting it so you can attach the new one. The new design allows you to access the clip with a screwdriver, the old style doesn't. Really it's only a 20 minute job.

Check where the leak is. If its leaking around the outside edge of the sensor where it presses against the oil pan, try tightening it a bit.
