I want to thank the Forum member who suggested the leak detector to find the vacumn leak on my engine, it worked great. I found leaks in strange places, like under a valve cover washer, RWJ
I sometimes use them on refrigeration systems. Just a guess. John

I use a machine at work ( Ford dealer) to find vacuum leaks in EVAP systems or engines, that generates smoke and is put into any place,under slight pressure to find very small leaks. Works pretty well for most engine vacuum leaks ( lean codes )I suggest anyone that has access to one to try it.
Here is the leak detector I got, http://store.lancastersupply.com/otc65letaple.html works like a champ. I found a leak between the crank and sleeve, around the intake and one where the dizzy mounted to the timing chain cover. The strange one was between the washer and valve cover where the paint had flaked. A little silicone fixed all of them. RWJ
when I first got the smoke machine , we had a 2000 F-150 come in with repeated lean oxygen sensor codes .... hooked up the smoke machine into a vaccum hose to fill the intake manifold .... smoke started leaking out the EGR valve and the hose going to the PCV valve .... the PCV hose was factory wrapped in a cover wich helped hide the leaking vaccum hose ..... found it in minutes , we had fought that car for months for that lean code .... it would take days for it to reset the code , smoke machine found it in minutes ...... exhaust leaks , power booster leaks , power steering reservior , basically diagnois anything oil , vaccum or exhaust leak related
