I went to the track yesterday and screwed up my tranny.. Going to Iowa tomorrow.

Anyways, while building boost at the line, I had a track official say that it looked like I was burning my clutch (obviously I wasn't)..
I saw it as well and I imagine its blowby.

Timing is at 24 degrees.

Vacuum pump leaks oil, and my number 6 cylinder has light scoring..
But I never had this issue before.

Anything else I need to track down?

 

What side of the truck was it on? Could be a exhaust leak???? just an Idea..

 

Sounds normal.

You might consider running a breather on each valve cover (like the big boys!)

 

Just a thought, Could the turbo be pushing air into the crankcase through the oil drain tube?

 

vaccum leak could cause this also.

 

Sounds normal to me, what happened to your tranny?

 

Stuck a clutch in the rear clutch pack.. We think.

Truck is at Daves right now.

 

Actually, my tranny has a 48RE front clutch drum in it, with the 47RE hub machined to fit it.
I broke the 47RE hub and also the input shaft is twisted 1/4 of a spline!
