Default Re: 33 Rear Main Leak

Your intake is 34 .
Fuel pump stand is early 34 " straight back " type .
You can put that stuff back together as it is not your issue .

Oil pump is newer and could possibly cause your issue if it has too much pressure-volume .

If I am reading your tape right it looks to be 3" spacing on main studs .
If it is indeed 3" it is babbit mains .

Did your leak start suddenly ??


How far was the tube fitting screwed into the main cap ?
If it's in too far it acts as a dam = leak .

Oil pump drive gear cover-gasket can cause your issue also .
