turbo ls1 leaking oil between motor and tranny!!?! not main seal! okay i just finished rebuilding my 347 replaced the oil pan gasket and rear main and rear cover gaskets a few months ago well i just got done a few weeks ago ironing out the end of the build and got her running on a base tune. good great awesome well now oil leak between motor in tranny. frustrated but i dropped the tranny and saw oil everywhere on rear cover bolts(all of them) but then i saw oil above the tranny on back of wiring harness so i pulled the intake and found oil around all my intake ports! and my on my pcv system the hose onto the passenger side valve cover was ripped so i replaced that and sent my turbo back to get rebuilt because it was blowing oil thro my inatke
well i knew oil thro my intake was the turbo but i was getting quite a few drops out between motor and tranny but there was also oil on guide pins of tranny and i mean everywhere so while i was at it i replaced the rear main and rear cover gaskets AGAIN what i wonna know is can oil drip from the top in between the tranny and motor??? or do you think i just had more than one issue like leaking rear main and the turbo issue any input would be great trying to get this project finished to drag it before it gets to cold any ideas would help!
also have a electronic solenoid to control pvc so that will take some pressure out of my crankcase
and no signs of leaking between pan and rear cover!

checked the opsu and it didnt seem to be leaking but that may be the first place to check if it leaks after i get it back together and running again...and doesnt seem like the vally cover either if it was the opsu would it spray oil rather than drip? and no unfortunatly i didnt rtv the pan/cover corners hopefully it wont leak!!
