Leaking Oil pan in front and rear at crank

I bought the #LRS-6675A Oil Pan and purchased a FelPro Blue One-Piece oil pan gasket to replace the old ones. I had the motor out of the car as I was doing a complete reseal with one of your reseal kits that you sold on LateModel. The block and oil pan were cleaned thoroughly and installed while on the engine stand. Every bolt was torqued to specifications. While watching the leak I took the car into a Ford dealership where a trusted friend works there who is a Senior Master level tech. Put dye in the oil and was able to spot the sources of the leaks right away. The leaks occur on both the front and rear locations of the crankshaft and not on the side rails at all. Both the pan and seal were inspected by myself prior to installation though I am no expert. Is this a common occurrence or am I just one of those "times". If it is a common though very undesirable occurrence, then is there good fix without having to drop the oil pan or replacing the gasket? Thank you for your time and assistance.

I had the same problem twice, just put a brand new fel-pro gasket on and it is still leaking.. so dissapointing. did you ever figure out what was wrong? - robert last year

Me and a friend of mine dropped the pan while the car was on a lift. Had very little clearance but was able to apply some gasket sealer or RTV to the corners and where the crankshaft bevels are at. We applied RTV in both the front or the back. It would have been easier to do it while on the engine stand, but like yourself, I believed the "dry install" the gasket manufacturer recommended. It goes to show you a little common sense can go a long way, and RTV is our friend. Since putting on the RTV and reinstalling the pan to torque spec, no more leaks. Sorry it happened to you too. Happy Mustang building :) - Sean last year

Sean, We do not have your concern as a "common occurrence" however if you have pictures available that you could email me I would very much like to take a look at where the leaks are present. Unfortunately I do not have a suggestion for resealing the leaking area which does not include removing the oil pan, Please email me at tommy.eskind@latemodelrestoration.com.
