1936 Ford 2 piece front seal question

I had my 1936 Ford LB motor rebuilt, And after it ran for about an hour I noticed the there was a small amount of oil leaking behind the front pulley.
I removed the front pulley and is seems to very serviceable ( not much wear on the sleeve) It looks like the oil pan gasket was installed between the the upper half and lower half of the seal up to the crank shaft. My question is , Is this the proper way to install the pan gasket, Or should the upper and lower seal butt up to each other and the oil pan gasket terminate at the seal.

any information would be helpful thanks Dave T
 
I don't put the ends of the oil pan gasket between the front seal halves. I bring the pan gasket ends up to the front seal halves, and then apply silicone sealant in the corners, on both sides, where the gaskets meet.

Looks like flatjack posted while I was typing, but we are in agreement :)
 
I got to take an original never had the pan off engine apart, the gasket went 1/2 way into the seal halves on that engine
 
I cut a piece out of the ends of the cork pan gasket, just big enough to accommodate the rope seal. The result is the cork pan gasket goes all the way to the main journal, but not between the rope seal halves. I use Indian Head Schellack to glue the pan gasket to the block so it won't shift during assembly, and preserves the gasket - rope seal interface. I let the assembly dry for 24 hours before mounting the pan. I prefer not to use RTV.
 
I guess those silly Ford engineers erred in making the gaskets too long; obviously they did not know what they were doing.
 
Yep, a lot of incompetence in Detroit in those days. Some of my friends tell me that Chevrolet engineers screwed up a bunch, too.;)

Given the low survival rates of period Chevrolets, I think they took top prize.


Seriously, I've put together at least my fair share of B and V8 engines not trimming the front ends of the oil pan gaskets and there's never been a leak. Maybe with replacement seals it's a good idea, but I only use NOS asbestos originals.
