aristech Posted June 10, 2020 Share Posted June 10, 2020 Has anyone had to preform a rear main seal replacement on a 1939 Pontiac 6 or 8 cylinder? I was looking at my 36 and it is very dry and not leaking underneath. But I have a friend that is saying his rea main seal is leaking. Thoughts?

Bloo Posted June 10, 2020 Share Posted June 10, 2020 I don't think a 36 has a rear main seal. I'm not sure about 39. Link to comment Share on other sites More sharing options...
Bob Shafto Posted June 29, 2020 Share Posted June 29, 2020 A 36 has two soft pieces of wood that are driven into the rear bearing cap. 1 Link to comment Share on other sites More sharing options...
