Re: Oil leak help...

Is the oil dripping from the side of the oil pan and between what two oil pan bolts? One method to use is to pressure wash the under side of the engine including from top right and left side (under hood) just below cam covers (when engine is NOT hot). Do not get water below the Plenum in the Valley. After the pressure wash it is then much easier to see fresh oil leaks.

Re: Oil leak help...
Sensor is circled in the picture. I cleaned up the oil when the car was on the lift and let it run for about 20 mins, you can see the fresh oil in the area. I think its coming out from the right side of this sensor? it does not seem to be coming from above but its possible I am mistaken. If I can find one of these sensors I plan on just replacing, cleaning it up again and running to see if this is the leak..

Re: Oil leak help...

Re: Oil leak help...
I have not pulled the sensor out yet but could try replacing the o-ring, I am still confused on what sensor this is (since its not on the oil filter housing), I am assuming its a oil-level switch?

Re: Oil leak help...
It is the crankshaft position sensor.
1990 does not have an oil level sensor.

Re: Oil leak help...
You can take out the sensor without any problem, it can be sticky but play a bit with your fingers and you can pull it out. I am taking of the - pole from the battery when working on electronics / engine.
If taking off the negative cable, computer needs to learn again after connecting battery. |
