Hello
I am working on a 1967 GTX with a 440 complete with a rear main leak. I have been unable to correct this issue. Previous owner replaced the stock seal retainer with a billet seal retainer from Mancini Racing, and new rear main seals while the engine was out of the car. I purchased the car and completed putting the engine back together (it was in the car needed parts belts, radiator etc to be reinstalled) Fired up the car “sounds great”, but after 5 min at idle left an oil spot about the size of 2”-3” diameter. :-(
I pulled the oil Pan, I then replaced the Mancini Racing seal retainer with new retainer billet seal retainer from 440 Source (list below)
200-1031 Rear Main Seal Cap - Billet Aluminum
109-1501 Rear Seal Cap Bolts - Set of 2 New
144-1000 Viton Rear Seal
144-1001 Silicone Rear Seal End Strips Kit
I am not able to physically pull the engine to try this with engine out of the car, looking for suggestions from anybody that has had work on their big block from a shop that they had good experience with. Or any suggestions on what to do while the engine is in the car. I am in the Sacramento area and looking for a shop with mechanic with better skills than me to fix my rear main leak.
Thanks for the read and any suggestions
