So with the ITB's mounted and tuned by Al, we had the 3.6 in the car and running well EXCEPT for an oil leak directly onto the passenger side header that made quite a bit of smoke. Frankly too much smoke to drive the car much. This was NOT Al's fault or responsibility to fix, though he took a few whacks at it. When I got the car home I was able to put it up on my lift, clean it thoroughly, and then run it to track down the oil leak. I had to do multiple cycles of this to finally identify the passenger side cam tower/chainbox interface as the culprit. It was leaking from the seal between the chainbox and cam tower, and running down to drip off the lower rear corner of the #4 cylinder head, to drip right onto the header. I considered doing a temp fix of rerouting the drip so it didn't land on the header and continue driving it for a while, but decided against it and took it apart.
Upon disassembling and removing the passenger chainbox I confirmed that did seem to be the origin of the leak. Unfortunately, that is where life and work got in the way and stalled all work on it for far too long. But I have the new seals and am ready to reassemble everything and retime the motor next week. Then there should be more progress and posts in the near future.
