vaccum

[supraman508]

I hear a hissing sound near my E.G.R vaccum modulator.does that automaticly mean that it's going bad or that it's an obvious leak?

most likely a vacuum leak somewhere i'd imagine...have you replaced any vacuum lines lately?

yes i have.and come to think of it,they don't seem to tight of a fit.they might be 4.5mm i think.or maybe they are 3.5.not sure.

What type of tubing did you use? if you used silicone you should consider putting zip ties at all the unions (like little hose clamps). Due to silicone's non porous and somewhat slick nature it doesn't always seal well, especially when connected to an older vacuum nipple.

yeah, mine is the same. but my car runs good for being 20 years old. if i where you, if your car is running fine, i'd just leave it alone and fix something when it becomes a problem. but thats just me.

Absolutely nothing wrong with silicone, it's what I'm using. Just make sure it's sealed at the nipples well.
