Hello all,
Just to close the loop on this as I figured out the issues...
First I want to say I took the old fashioned/dangerous approach with a can of brake-kleen and started looking for leaks...
By jove I found it, well multiple leaks...
Thanks to spazzz and his link to the factory vacuum lines as that was one of the issues...(the elbow under the map sensor line was cracked INSIDE the elbow, when I went to remove the elbow, the line crumbled)
The second vacuum issue was with the throttle body gasket, it appears it was torn? during install...Brake-kleen found this one quickly...
Lastly, the knock sound was due to about 1/2 to 3/4 quart of oil too full in the case (not sure how this happened?)....I did an oil change and filled to the proper amount and voila!, the knock is gone...
Hope this helps someone in the future,
GoldGTP
