A bit more information from today...
check valve on front PCV is okay, Inspected connections from turbo outlet and pancake pipe, removed rubber inlet and outlet IC tubing then cleaned and re-installed - all looks okay. (except for the three tablespoons of oil!!)
Visually inspected exhaust side of turbo for visual signs of soot - none found.
Block 32 data is -.7 and +5.2
I'm beginning to think it might be the turbo going bad... any thoughts?!?!?! Damn TD1 campaign!!
