How many oil sending units does a 92 lo3 have? I know of the one above the oil filter but cant find one by the distributer. Does it exist?

 

That is where older cars always had them i'm pretty sure that with the newer electrical sendig units theres only one above the oil filter.

 

The second one is located if staring at the engine from the front its to the right of the distrib. Take your air cleaner off and look right behind your coil. Its that bell shaped thing. I think it has one wire going to the top of it, I found it easier to take it out if you take your coil out, this way you can use a regular open end wrench to reach it. Hope this helps.
