Re: Vacuum Leak
>WD40 spray works fine, too! Great for those 5K manifold gasket failures.
Sorry, but I think using WD40 to hunt for vacuum leaks is a VERY bad idea.
If I'm not mistaken, the oil in WD40 is a SILICONE. SILICONEs contaimnate
OXS sensors. That's why we are now being warned not to use silicone
sealants when installing OXS sensors. Well, maybe if you want a reason to
replace your OXS, it isn't such a bad idea. :-)
BTW, read the label on your can of WD40. The propellant is PROPANE!!! I
know of one source of professional auto repair info that has the mechanic
search for vacuum leaks with an unlit propane torch.
