340 rear main seal leak/gush
Has anyone ever run into this before?? I cant figure out what could have caused that substantial of a leak.
Have you done a CC pressure test yet?
If it's the oilpan, you'll know right away,
also check the distributor to block interface.
After the easy tests are done,
Drop the inspection cover and listen for air escaping in the BH, There's several places back there that can gush oil.
During the Air test, the VCs have to be sealed, and I pressurize thru the dipstick. I set my regulator to no more than 4psi. You never know how tight the rear cam plug is installed, and if it blows out, don't say I didn't warn you .................
BTW
The oilpan is in fact off a 340 right. and
for sure not off a 360, right.
I mean, I had to ask.
