Vac Leak

[Altiery54]

I know i have one somewhere but am having problems locating it. Tried the soap and water watching for it to fizz, and to no avail nothing. Replacing IM gasket friday just at the pure possibility it may be distorted a bit. Any other helpful advice? I can visibly watch my boost gauge fluxuate indicating the leak..............

Soap and water won't "fiz" on a vac leak, they would get sucked in, Use brake cleaner, and when you hit a spot that the idle changes, that's where you're vacuum leak is..... there are other methods as well.....


Soapy water is for finding air pressure leaks, as in air leaking out

already tried the brake fluid

I hope you meant brake parts cleaner..... did you check the vac line that runs to your boost/vac gauge

Yeah, but vac lines and fittings are the most common, don't forget to check the boost bypass valve (you SS is supercharged correct?)

a general plenum vacum leak usually holds a fairly steady low vacum condition...a fluctuating vac reading usually indicates a bad valve sealing issue on one or more cylinders or a vac leak on one runner (ie injector seal leaking)

i told u i have those vacuum lines if u want to use them

Or a vac line that goes to a port that sees manly one cylinder

true but most manufacturers know of the fluctuations and so most vac lines are at the common plenum area to eliminate pulsation....

Oh I'm not arguing with you james, but I've seen where a vac nipple ism it would read pretty much on one cylinder only......Sometimes space limitations force vac hookups to be put in bad spots

Not much choice, if the vac port is on one end or the other, under vac it will majorly read the cylinder on that end(not only that cylinder, but enough isolation to cause pulsations)

Edit, But I only see one vac nipple though

 

[Turbocharged400sbc]

/\ he said nipple lol

 

[02BlueGT]

/\ he said nipple lol

I think he said it two or three times

 

[Turbocharged400sbc]
