Hi I'm still working on the 53 chevy thanks to your guys help she is running nicely but now she leaks at the front of the pan we have changed the gasket again last time we used the rubber seals front and rear and she leaked worse the second try we used the cork with a coat of copper coat the pan looks pretty flat checked it with a straight edge etc. I trimmed the seal where the corners meet thinking I would get the corners better was this a mistake??? as it still leaks in the same area and now I think we over torqued the bolts...... ordered another gasket to try one more time any thoughts please help again ...by the by she has high oil pressure cool and after warm up it still runs around thirty pounds or more when above idle speeds idling warm it comes down to 15 pounds (it is a new gague) Thanks for your thoughts Scott B.

Scott; The oil pressure sounds fine. Is this the 235 or 261? Regardless, don't trim those rubber seals. I like to use 3M Weatherstrip Adhesive to 'glue' if you will, the gasket to the pan. Then, use silicone to adhere the rubber seals in place. I always put a generous 'dab' of silicone at each end of the rubber seals where they meet the block. Make darned sure that all of the block and front/rear seal areas are nice and clean. Loren SW Washington

Thanks Loren it is a 235 and we used the cork on the end seals that is what I trimmed just was wondering if it had too much pressure and it was blowing past the seal the cork seemed a little long and I thought it would leave a gap ??? thought about replacing the pan but they are sure hard to find these days it looks like it ran over a tree stump or something but it was silver soldered and holds oil fixed her up best we could not sure now if the ends are out of round or something any thoughts Thanks Scott B

>> looks like it ran over a tree stump or something << Bummer, dude. (Got that from my grandson.LOL) I'd try straightening the pan the best I could while it's off, but if the front and rear 'U' shaped areas are damaged, a LOT of silicone? Just try and be as meticulous as you can when reinstalling the pan and hope for the best. It's been soooo many years since I worked on one of those. Could it possibly be the front crank seal that is leaking, rather than the pan? I can't remember how they were set up. Could you take a pic of the pan and post it? May help? Loren SW Washington
