Hi everyone,finished up rebuilding my engine and transmission and am ready to install in the lower crankcase.Have fitted new rope seals to front cover and lower crankcase with slight protrusion on each half and did a light test fit lightly seating the cover to the lower with a test piece of roundstock same diameter as the crankshaft.Have a good fit.My question is is the proper or best way laying down the gaskets is over the rope seals?Thats how they are made,looks as if they will contact slightly the crank.Is that supposed to complete the block to pan and rope seal sealing?If this is correct I will be ready to finally get this together,and hopefully finish the assembly to get it all bolted in the chassis as its all ready to go!!Thanks!

Thomas, my thoughts are that the gasket material does not make for a good seal against the crankshaft. So I cut a U shaped relief in the pan gasket so the gasket fits around the rope seals. That way the two halves of the rope seal crush against each other for the best seal possible and the pan gaskets can work as intended.

It works for me.

Don't forget to soak the rope seals in oil for a few hours or overnight before installing.

Cutting the U shaped relief will work. Model A's using the same rope seal just had the gasket pinched between the seals. So ether way should work.
