Oil pan gasket..

[Pickerincal]

Putting the oil pan on a 47.. Are these notorious leakers? Looking a the fact that it seals over the block and the front and rear cover it seams it might be an issue. Do any of you put anything on your oil pan gasket like Permatex? Or just throw down the cork and call it good?

Thanks,

Brian

I take the oil pan and pound the lip flat to start with as many are warped from being over tighten through the years, use a sealer like indian head or permatex aviation sealer, clean the bolt holes and bolts also

Be sure the bolt holes aren't pulled concave from over-tightening also. My Dad taught me to use the ball end of a ball-pein hammer to flatten this area. I also like to chase the threads in the block and give them a shot of solvent to flush out any debris. You can use the spray gasket sealant on the pan, that keeps the gasket from moving all over. I was also taught to not use sealer on the block because it may need to come apart again someday. Good luck. One last though, be sure everything is clean and don't pour the oil in until the pan is on and the drain plug is tight! John

Thank you.. The one I have looks to be pretty straight. I will put it on a straight edge/flat surface and check it out.

I...used Permatex oil resistant gasket sealer on the oil pan surface, after doing my "underhaul", new rod and main bearings. A dab in 4 spots on the machined surface of the block that weren't quite flush, to help seal. I very rarely use Permatex on a machined surface. Then I evenly tightened all bolts. Don't overtighten, they don't need 200 ft lbs lol. Check again after a week of use, and retighten. Mine leaks not a drop.

Wish I would have used aviation thread sealer on bolt threads. Will next spring, when I do my in frame overhaul.
