Mass oil leak!?

We did an LS1 5.7 swap on a 951. Using TPC oil pan, and filter block. Everything was fine for a couple months, but then later down the road when the engine warmed up to operating temp and driving, there seems to be some sort of large leak somewhere near the back half of the engine. So bad, it would all land on the exhaust and burn the oil and cab would fill up with smoke and leave a large trail of smoke behind the car as well. Has anybody noticed any issues with leaking, with the TPC oil parts??? Or is there something wrong with my engine? Any ideas??

As much as its gonna suck, get under the car and clean everything up. Then start it and watch where it's coming from

I’ve already done that a couple times and can’t see anything. Only time it seems to do it seems to be while it’s driving on the road. We even revved it up and all, nothing.

Could be something as simple as a pinched o ring on the oil filter block, a leaking oil pan gasket or as bad as a rear main seal. You'll have to try and find a way to locate the leak.

As i just finished a recent post about installing the TCP oil pan, it sounds like you may be getting corner leakage related to the oil sloshing around due to stop/starts and turns...aka driving.

If you did not apply the correct silicon sealer, or the cover/pan clearances were too large, either of these may be the problem.... Just a guess. You did replace the rear pan bolts with correct units...right?

The late start on the leakage adds to the mystery.

The clean and check approach recommended by Spense is necessary...just don't drive to far before you check for the leak source.

Good luck and keep us updated!

Ouch
