I found my White Smoke problem. If you ever change your Plenum make sure you install the PVC, I never did and the intake was sucking all the oil out of the motor. I drained it today and it only had 1 1/2 qts in the pan. I had good oil pressure though. I changed the oil and ran it a good hour and it is all back to normal.
Just turned out to be a major job to replace my leaking elbo on the front of the manifold:
Sent the heads out for valve job and mill check( I thought I blew the Head gaskets)
Replaced the Plenum, original problem-ruptured.
Had 2 no start conditions, Crankshft and Camshaft sensor replaced. The second
was a no start, no power windows. This was from the corroded Shorting Bar or
Ground Bar under the drivers rug near the sill plate- danp and corroded.
This Board was a tremendous help and I have to thank you all. Cheers !!!
