So after replacing the upper oil coolant line...which was dumping a quart of oil a day...i found some sort of sensor that is leaking....any idea what it is called and or why it would be leaking?


It's dead center of the picture

thanks

 

Oil pressure sending unit.
AutoZone, $15.
Its easier to change with the oil filter off.

 

sweet thanks!!!! must have a seal that leaks?


Ordering now, thanks again!!!!

 

No, no seal, it cracks.
It is make of ceramic, it cracks and then leaks.

 

It is a good time to completely clean that area before you get started.....

 

thanks everyone....part is on the way!!!

 

So the new one seems to have a 7/8ths nut on it....but the old one is bigger it seems...anyone know what size?

 

Its huge, thats all I know.

 

most senders are 1" or 1 1/16" (I have a stepped socket that was made to fit either size)
