Curious about something

ok. i was changing the oil in my 99 camaro this weekend. changed it, all done, and started back up, and let run for a few. when i heard this loud ass hissing noise. i started listening around the engine bay. and heard it was deffinatly a vacuum leak. tracked it down to a vacuum line on the intake, directly behind the throttle body on the passenger side. the whole like was rotted through. and was stretchy. well, i went up to autzoone and got a piece of hose for it, fixed it right there. but noticed. that this line that runs from the intake hooks into this huge vacuum line that appears to run into the car itself. for hvac? i dunno. but i noticed that this line has a grounding clamp and wire hooked up to it. im curious as to why gm would run a grounding wire to a vacuum line like this??? any ideas?

i'm not quite sure what "hose" your talking about, but maybe sensor wires are in that hose. on my old G/a they looked like hoses going into the car but it was actually a tube like hose that held wires in it.

You talking about the PCV valve?

i think i might. im not sure. but as i was putting the new hose on i could hear like a little ball earing floating around in it. and noticed it was a metal piece with a nipple on it for the hose to go on.. and im retty damn sure, that gm wouldnt run a vacuum line through a "hose" with wires through it. im just curious as to why this piece is grounded. it has rubber hose on one end, and plastic like wrapped hose on the other. maybe my car is just speshul. haha

lol yea. well i wasnt quite sure what hose you were talking about. when i was talking about the hose i wasn't talking about a vaccum line inside of it too. but yea Ed knows his shit..minus the bypassing window switch

sorry ed

i did enjoy reading that thread tho. our pcv valves are designed shity
