Totally Dissapointed!!!!!

I had a thought today as I was thinking about your oil pressure problem. Dis the machine shop boil the block to clean it? There is a plug in the block that is under the rear main cap that if out of place can cause all sorts of oil pressure problems. If you cook the block to clean it the plug can come out. Machine shops that don't know Mopars wouldn't even know it was there. Just a thought. toolmanmike
