Oil Pan Sealing Tips LA Small Block?

Bill, was the 1 piece plastered with silicone at the ends ? Silicone will cause the blue seal surface to NOT seal and leak. I've installed several of the 1 piece ACCORDING TO THE DIRECTIONS and have had no leaks.

I haven't used the 4 piece either cork or rubber for many years. As has been mentioned, change the rear seal and install the ends offset from the cap seam by, at least, 22 degrees with a minute touch of gasket sealer on the ends, not silicone.
And, as has been also said, for any of the various gasket types being installed, ALL surfaces need to be sterile, If a white cloth doesn't come back without any discoloration, I keep cleaning and the final clean is with acetone.

That was too many depleted brain cells ago Mitch ....I guess I'm too old school....

Lots of good advise to choose from here!

Edit: Just now thinking, between you, me, and Lynn, there must be well past 150 years of experience!!

Thanks for the advice fellas. I have replaced the rope rear main seal already with a rubber two piece seal and used just a small amount of black rtv where the two ends meet. I used red anaerobic sealer between the block and the cap since they are machined surfaces. I am doing the front cover gasket and seal, valve cover and the intake gaskets as well. None of them ever appear to have been replaced and the engine is quite an oily mess but it runs very well. When I’m done it should look as good as it runs I hope!

You working on a Pontiac ?? I haven't seen a rope rear seal in a Chevrolet in 55 years of working them.

Ah, I didn't notice this was in the Mopar forum....

I do have a soft spot for Mopars. I bought a '72 'Cuda new for my 20th birthday.

No worries Mitch. I've always liked Mopars as well. The truck I'm working on now has been a part of my life since I was about a year old. My dad bought it in the mid 80s and used it for his business for about 20 years and then passed it along to me several years ago since he retired. Just been slowly working on it, fixing all of the issues it's developed over the years. I figure it will be a pretty cool tow truck for my Mopar cars in the future.
