97 ZJ with 318
 

yesterday, while at a stop light, I noticed my oil pressure gage dropped
down to zero. When I rev up the engine the gage would read normal (over
40). Let it idle and it now drops to zero. If I take it out of gear
(neutral or park) the gage would read normal for idle (just below 40).
Question: where would I find the oil pressure switch on the 318. I can
find the oil level switch on the pan but I am not sure where the pressure
switch is. Any ideas with a good drawing or photo would help

It is located at the top rear of the engine behind the intake manifold next
to the distributor.

if it's like the 4.0, it will be located by the oil filter, but I
think it might be up by the distributor like the other 318 blocks.
Should look like http://www.rockauto.com/ref/ACDelco/...html?C1818.jpg

Like others have already said it is next to the distributor, in
this picture the exposed distributor rotor is pointed to it's silver
