before i get home and start tearing into my engine again, i want to see if anyone has any insight as to what could leak oil in the back of the block(between engine and trans). i tightened the 3 plugs around the cam housing on the back and wrapped them in teflon tape. what else coould be leaking that would cause about 4 quarts of oil to pour out in less than 10 seconds. pics would be a big help. reference my last post: http://www.gaownersclub.com/forum/sh...=102225&page=7

i have no idea what any that means except the link didnt work. i found the source though. check y build thread for the answer if you want to know. and yes, it was close to 4 quarts in less than 10 seconds.

4 quarts in 10 seconds should be an obvious leak. I'd put a catch pan under the car and pour some more in and see where it comes rushing out. My oil doesn't even drain that fast through the drain plug so your leak must be bigger than the plug hole.

sound like a rear main seal, an actual hole in the block, or a missing or severly damaged oil pressure sending unit of switch.

Sounds like the rear main seal took a major crap.

it def was not the rear main seal, it was a missing plug on the back

Wow, that was it? What plug was it anyway? Now you can finally get that motor running, you've put a lot of work into it.
