I have just found a method to make your own diagnostic smoker for checking the vacuum as it could save us a lot of headaches and pennies I would like to share it with everybody as a late Christmas present.

There's a detailed write-up in another of the forums on this site, maybe the same one...

Bear in mind they won't find every problem but usually work.

You will find the write up I did here

Thanks for information. It looks very nice.

This actually worked...believe it or not...to find intake manifold gasket vacuum leak: cigar, soda bottle, tubing. I suppose thanks are due to that YouTube nitwit Scotty Kilmer....
