Do you gents know if you can use the later magnum style single piece pan gasket on an LA motor? Single piece seems like a much better design.
 
I don't think so.

LA pan is different between 318/340 and 360.

Mag pan is the same 5.2 and 5.9 and is closer to 360 style.


I'd LOVE a single piece 318 pan gasket, though.
 
I used the Felpro OS 34409 R Magnum oil pan gskt on my 71 340-416, just cut the one piece gskt up to match the old style side pieces and use the old style end pieces with a dab of RTV in the corners. Works nice with no crush issues.
 
Thanks Gents, looks like I'm stuck with O'l four part gasket. I appreciate everyone's input.

You just cut the timing cover area?

Those corners are notorious for leaking.

Was there an improvement in sealing, and if so, why?


Thanks much.
 
Yup, just lay the old style on top of the new one piece and cut thru the steel core. Seals up way better, doesnt crush, and wont shrink like cork. Gotta seal the corners with RTV no matter what gasket you use. Worked great on my Milodon pan#30935.
