vacuum leaks
What do you know about finding vacuum leaks?
What is the best to locate a vacuum leak? How does a professional shop find a vacuum leak? |
RE: vacuum leaks
The most commonly used way of finding a leak is spraying carb cleaner on the vacuum hoses and listening to the engine change RPM when you hit a leak. I don't do that however, I simply replace all the hoses periodically. There's only what? 6 vac lines on the car? About 10' of silicone hose fixes it. If it's not a hose than carb cleaner works I guess. My mech simply finds them by ear.

RE: vacuum leaks
Carb cleaner is the quickest, but if I can't find it with that and I'm sure there is one, then I break out the smoke machine. Its mostly used for EVAP emissions leaks, but works great for vacuum leaks too.

RE: vacuum leaks
if i am correct that line that goes through your false bulkhead runs to the boost gauge and the over boost protection switch

RE: vacuum leaks
thank you boostpowered is there any chance you can tell me where that is cause what i guessed it was was the hose that went to or came from the big plastic thing that points at the radiator very close to the fan and thats what i connected it too but i dont want to break something and yes the car scoots a bit more it doesnt woosh like it did before
can you where this unit is or what to look for so i can hook it up correctly plz? |
RE: vacuum leaks
post some pics it will help diagnose the problem better . are you talking about the apc with three silicon lines sitting on the drivers side above the radiator fan that has a electrical connection that is essentially your boost controller
