I've got an oil leak running down the block on the passenger rear side and dripping off the front of the bell housing. If the truck is just fired up and idling it doesn't leak at all, once you start driving it and stop you can see it dripping off. I noticed it because I was dragging a heavy boat through some hills and it actually started burning off on the exhaust and blowing blue smoke.

At first I thought it was probably a lower VC gasket but I don't see it leaking from that. Is it possible its actually coming from the HG? I don't have any other signs of bad HG's (pressure in coolant system, coolant in oil, etc) so it would suck to have to change them over an external oil leak...

Anything else it could be coming from? or is the HG a likely culprit?

I have looked and don't see anything. But I also cant get a real good look with it all assembled.

Sounds to me like it would be coming from the turbo oil drain. The oil drain connects right in front of the bellhousing
