Hi,

As mentioned my 1999 Chevrolet Lumina (3.1) has an oil leak above the starter. Last time the starter failed because it was full of oil and dirt. Then it had a big oil leak which resulted to be the oil pressure sender and was replaced immediately in an autoshop.

Almost 4 months has passed and the leak started again, draining the engine oil to less than 1/4. Also, the low level was very low and the light sensor didn't turn on. I checked it myself and cleaned the engine with degreaser and it was leaking again in the same place (oil pressure sender).

I can fix this myself better than the crappy autoshop if I knew what it was.
The question is, what is really the problem here?

 

Is it the oil pressure sensor? Is it screwed in enough, assuming it's not cross threaded?

 

Solved! I changed the oil pressure sensor and no more leaks, maybe the previews one was defective/
