I'm having trouble figuring out how to post pictures, but I do have some tubing that runs from the throttle body to the IP. It appears to be made of a hard plastic material, and I don't see any cuts or breaks in the tubing. I have replaced the rubber hose that runs from the vacuum pump to the intake manifold so it should be good.

I will see if I can put a vacuum test rig on the hose running to the IP to see if holds vacuum. Also my offset woodruff key and valve stem seals arrived in the mail today. I started prep for the woodruff key install on the camshaft gear this weekend, but had to order a new seal for the timing chain tensioner from Lithuania, so it may be a few days before I get everything back together for a test. While I am waiting I put some marvel mystery oil in the cylinders in case I have some sticky rings. I am throwing the kitchen sink at this car, as I really love driving it, with exception of the smoke screen....

Thanks for all the good sugestions on what to try.
