Gasket problem

Recommended Posts

Installed a new oil pan gasket the other day and have a leak at the rear seal. The one I had was 9" long and sealed with permatex. The replacement spare I received had an 11" long by 1/4" thick rear gasket. Any help to how to install it without a leak would be greatly appreciated. Car is a 1930 Model 70 Chrysler 218.6 6 cylinder.

It isn't the rear main seal---it is the flat gasket for the oil pan How long should it be?

Tim, Typically that flat 1/4" wide piece is approx 1/4" loner on each end or 1/2" longer overall than the radius. If your old piece was 9" long your new one should be the same. I like them to crunch up slightly when installing to press fit the piece into the oil pan. A dab of Ultra Black sealer at each end will help to seal out the elements and seal in the oil.

Thanks, mine were flush with the top of the oil pan when I removed it ( and it leaked) so I replaced it with the same length ( and it leaked) I'll try one a 1/4" longer on the each side.

G/day Tim,

Yours I suppose should be the same as my 66, all I do is make sure the cork or neoprene is thick enough to squeeze under the keeper on the sump ( where the cork fits) then make it long enough to just be about a 1/8 above the sump gasket a generous squirt of a good sealer ( I use the black Toyota stuff) in each corner where the sump gasket and the cork meet, never had a leak,

Regards

George

Tim, your oil pan gasket ends for the early 70 series should be 15/16" x 9-1/4" x 9/32". See attached Victor gasket guide.

replaced the gaskets and used 9 1/4" long gaskets per the info Harry sent, sealed them with black permatex instant gasket---no leaks! Thanks Harry! That extra 1/4" did the trick.
