hi there, i have this annoying oil leak that can't fingure out on my 94 ssei (heavily modded ) I have changed the valve cover gsk,oil pan ,checked the oil pan, i have cleaned everything and watched for an hour, seems to be comming out were the fire wall side of motor, were the mount is attached to the motor, is it possible that i have cracked the side block? i drive the **** out of this car on a daily basis, not too many cars can keep up in the eight mile,has any one had a block failure ??

Did you check around your oil pressure sensor?

yes i was hoping that it was just as simple as that, but unfortunitly it appears that the leak is comming from were the rear motor mount is attached to the side of the block(firewall side), i guess aside from the o.p.* there'* not much else that nomally leaks in this situation??any moded bonnys have problems with cracking blocks?? im leaking a half cup full of oil per nite on my driveway !! thanks for any help Brad

check your oil filter gasket....
mine failed not long ago, and it pissing near the rear motor mount and all over the place as well

hi there, is this oil filter gasket on the oil filter it'* self, or on the shaft the oil filter threads on to ?

its on the oil filter, just change the filter and your set

You mentioned being heavily modded. Ok, this means you should have done a lot of work yourself. This means you realize there'* a transmission mount on the driverside and a trans to engine mount with a dogbone underneath on the passengerside. Please describe where you see the leak.

Does it appear to come from the transmissiion? Is it rolling down off another part of the motor? Being a 94, you'll have oil lines running to the radiator, could it be them?

Not to hijack this thread, but my 92 SSE has an oil leak that drips off the rear of the oil pan. Does yours leak the same way?

yes it leaks the same on the rear p/* (engine oil)
the tranny is brand new , i am wondering if the car will take all the hard shifts from this modded tranny (2500 stall , adj vac modulator, hardened clutches,steeles, 3rd and 4th have allot of hardened parts, sonnax, lock up kit, sonnax shift kit, 1996 ssei pump, better design) the only thing i didn't upgrade was the input shaft, $400 was too much money, i had a local tranny shop build the tranny, the car wouldn't run very well with out the sinister chip, they had to adv the timming 7 degrees !! but it beats hemi'*

PS side eh.. There'* not a lot over there to leak. Valve cover, LIM gaskets, rear engine cover, rear main (can, usually doesn't), oil pan gaskets are the only things I can think of.
