Hi Bert,
Yup, spring it will have to be to get to the dyno- lots of salt spread on the roads here now.
I did figure out how to smoke test the ITBs and realized that I forgot about having the vacuum lines from 1,3,4 and 6 on a common manifold! So I was running smoke out of the other stacks due to vacuum lines. Lines 2&5 feed my MAP.
I clamped the vacuum line at each body with a proper clamp plier and smoked each stack with intake valves closed and got good results with my OTC smoke tester.
