troubleshooting oil pressure

There are two trick plugs in Mopar SB

One is the one mentioned above. This is a screw in plug behind a second screw in plug in the rear of the block. You can see it looking down the dist. hole. One guy on here actually installed it through the dist. hole

The SECOND is a drive in plug which is installed before the rear main cap is installed. This goes up in the vertical gallery going up to the oil sender. There is a way that you can remove the oil sender and stick a rod down in and measure to determine if it is there EDIT READ BELOW

THIS WOULD NOT prove there is not a hole in the plug from say, rust or hot tanking.

This is a photo of the one in the dist. hole. The wrench is coming through a plug in the rear wall of the engine

You take a rod or wire, and insert down from the top through the oil sender hole. If the rod goes down much more than 7" the plug IS NOT in there

You can check to see if the one Rumblefish mentioned is there easily by inserting a 1/4" piece of round rod down the oil pressure sender hole. It should only go down about 7-3/4". If it goes much more than that the plug isn't there.

The one Deadly Dart mentioned can be seen with just the dist. removed. Like he said put the drill in and spin it and look down through the dist. hole and if you see oil gushing out there's your problem. This plug were talking about is screwed into the drivers side rear of the lifter galley.
