Big oil loss on rear sid

[dansluck]

Werner, I would remove the rear cap and check the clearance with plastic gauge (green) if you can get it. Another option is to use aluminum foil. A strip folded to about 3/8 x 2 inches (measures .002 of an inch thick) in the rear cap. Turn with hand crank just a little to see if it moves. It should not. It should hold with 2 strips and turn with 1 strip. Remove shims as needed. If the thrust is broken in the block check out Berts Model A Store on-line for a bronze rear main seal with thrust. Part # A-6336. Good Luck! Dan in Reno Nedada

"Bronze Rear Main Thrust Washer- USA made. Replaces the A6335 rear main seal. Gives the engine a better rear main thrust surface." dansluck, how do you even install that thing? Can he do it with the motor in the car?

Yes, that would be very interesting to me as well. I found this video:

According to it, the installation only requires to remove the oil pan. If I understand correctly, that's related to the crescent-shaped sealing washer too.


Dankeschön!
