got a leak from the back of the engine and the oil leaks down both sides of the bellhousing, but being a 2001 V12, there isnt the most amount of room to see. I know these have problems with headgaskets etc, but i took off the engine covers, throttle butterfly and intake pipes off to find some more room. I came across engine breathers that were split and some were squashed so i thought id replace them first as it could cause the engine to breath very heavy. So after cleaning, gave it a good run, and put it back in the air, and still had fresh oil coming down the side of the bellhousing again! Any ideas?
