Hi Stude8, Thank you for your help. The car was fitted out with a canister style oil filter, not the screw in type. It is a fram filter. I am a pretty good wrench turner, but some of this pot metal stuff I have not run into, especially in carberators and oil pumps. I feel pretty good about the engine once I get the oil pump body replaced. I am pleased with the work I have done on the engine, knowing that there is always a "get-to-know-you" time period. You have helped explain to me why the oil pressure dropped. The thing I find hard about this car is finding parts, and I have found this forum very helpful. I am thankful people like yourself are willing to help novices. The car is not immediately avialable. I was driving it down to have it reupholstered when the problem occurred. I am so glad it happened now and not on a tour. I will send you photos later this week of the car oil system. thanks Paul
