Rooker75 Posted January 7, 2016 Share Posted January 7, 2016 Can anybody suggest a good forum to ask some noob questions about car repair? Google seems to be useless for this sort of thing. Or maybe someone here can help? I've got this ancient 1990 half ton Chevy pickup (c1500) and noticed a busted line while I was replacing some filters. Anyone know what the heck this is and do I need to get my shotgun and shoot the thing? It feeds into the carburetor, whatever it is. Link to comment Share on other sites More sharing options...
Aurielius Posted January 8, 2016 Share Posted January 8, 2016 Chuckles..see that circular air filter?...the carburetor is directly underneath it, perched on the top of the engine block. If it feeds into the carburetor then it's most likely a fuel line. Link to comment Share on other sites More sharing options...
bben46 Posted January 8, 2016 Share Posted January 8, 2016 If that is what I think it is, it is just the hose that goes to the PCV or Positive Crankcase Valve. link: https://en.wikipedia.org/wiki/Crankcase_ventilation_systemYou can drive with it disconnected for a short while but your engine may run rough. It is an easy fix. Your local Auto parts place should have a replacement PCV valve for a few bucks. Here is a quick look at c1500 parts lists - it can vary by year & other factors: http://www.autopartswarehouse.com/search/?Ntt=Chevy+C1500+PCV+Valve If it was a fuel line like Aurielius thinks then you would have gas spewing all over when you tried to crank the engine - Not good and a serious fire hazard.

Lisnpuppy Posted January 8, 2016 Share Posted January 8, 2016 I asked my husband about this and he agrees with Bben. You need that piece to hook it together and its part of the emission system. It like recovers gas fumes and mixes it to recirculate it. It would prob run but it won't pass any test and may have prob running WELL as it won't get a good mix of whatever. Keep in mind I have had this info in my head long enough that it has been female translated by a non-gearhead female. lol Link to comment Share on other sites More sharing options...
Aurielius Posted January 8, 2016 Share Posted January 8, 2016 Hell I'm willing to bet Bben has owned more trucks than I ever have. So go with him. Link to comment Share on other sites More sharing options...
Lisnpuppy Posted January 8, 2016 Share Posted January 8, 2016 I just pull out the husband and dust him off and shove him toward the nearest toolbox. :) Link to comment Share on other sites More sharing options...
Rooker75 Posted January 10, 2016 Author Share Posted January 10, 2016 Appreciate it, folks. It's been running like a one-legged zombie recently, which is why I was under the hood to begin with. PCV valve does come up a lot on what I've been able to google, so that's probably right. Link to comment Share on other sites More sharing options...
HeyYou Posted January 16, 2016 Share Posted January 16, 2016 PCV is a closed system, so, valve on one side, just an elbow on the other.... So, make sure you get the piece you need. Two valves make for a non-functional system. Link to comment Share on other sites More sharing options...
