Thanks guys, lots of good advice and experience there. I note the PCV of Dave's in on the right….so I may just swap to eliminate the PCV / oil carry over issue and see if the the small amount of smoke at start up transfers over to the other bank. If not, then it looks like possibly the seals… Mike Drew had a look before it was shipped and thought it may be oil carryover…but it only happened once with him and Gary Choate and does not happen on the open road.
My inlet manifold is taller than standard and the PCV is connected directly to it by cylinder 5/6. I will also look into new breathers as suggested and see how things progress.
Thanks again!
