I *think* there is a plug/bolt on the back of the engine right in that area.. has something to do with the balence shafts (which i dont have) that is the ONLY place i can think of that could make it leak this way..

if i fire it up and crawl underneight within 5 sec i can see a nice constant stream oozing from the bracketed area... the oil is brand new so its kinda hard to see.. but its definatly from that area.


Am i right? what else could it possably be?
 
the rear main would be my first guess or the gasket that goes between that and the block.. I honestly dont remember anything else that can leak oil inside were the tranny bolts up.... either way sucks for you :thumbdown
 
well.. its kinda high up to be either of those.. and also its coming from between the tranny plate.. and the block.. so whatever is leaking is in that area.. the rear main and its gasket are not..

i dunno
 
Reply from slowboy is that there is an oil gallery plug in the area pointed out in the pic, guess i better drop the tranny to check it out..

and btw, aside from this leak (which im sure is prolly my own fault) the engine fired up and ran as smooth as glass... even without balence shafts and crap and with solid urithane mounts, the vibration was hardly more than stock.. i think they did a very excellent job on this block..
 
Well i got the tranny and everything out (FUN!) and sure enough.. tha toil gally plug was only in like.. hand tight.. and not torqued down at all...

i put some teflon tape on it and ran it down pretty tight..

hopefully that fixes it :mad:
 
well everything is back together now, and no leakage whatsoever as far as i can tell..

only stupid idle surge :cry: :thumbdown
