coolant line question

[ramren16]

ok today while messing around under the hood i notice that there was a air leak sound coming from the coolant line that goes to the pcv valve(throttle line rubbed a hole in the plastic line) my question is it ok to keep driving my X with this hole in the line, all it does is make a hissing sound no coolant leaks for some reason. and do i just get the new hose from the dealership or what. any help would be great oh ya i have a 01 sport

I'm a little confused which line you are talking about. There is no coolant line that goes to the pcv valve, just a vacuum line. Could you maybe post a pic?

i have never seen coolant ran to a pcv valve my self
the hose runs from the pcv to the radiator?? or does it run to the air intake

i bet you could get the hose a lot cheaper at the parts store instead of the stealership if its not a formed hose you could just get some bulk hose to replace it

now that i look at it a little more it is a white vacumn line coming from the fuel vapor managment valve under the battery up and under the the coil. is it ok to drive with a hole in that line and what does this line do, i also asume i can get this from the stealership right

As long as it's just a small leak it's fine to drive it like that. If it's a larger leak though it may cause a lean condition. Also if the inspections in your state include a visual inspection of the evap system it may not pass with a hole in this vacuum line. But as long as this hose is not formed it's probably cheaper to find a replacement hose at an auto parts store.

No...I'm sorry...I totally disagree. If it's a vacuum leak, fix it. I don't care how small you "perceive" it is. (1) It's unmetered air and will upset the air fuel ratio. Since you don't have any idea of knowing just what it's doing there, you could be dangerously lean on a cylinder. (2) It's unfiltered air and will allow dust and dirt into your engine. (3) It's preventing the proper operation of the PCV valve. That allows moisture and acidic gasses to remain in the crankcase. It's just foolish to leave something like that.

I agree with you and if it was my truck I would fix it right away. Sorry I should have been more clear in my original post. I didn't mean to never fix it and just leave it as is. I meant that if he doesn't have time to fix it right now with the holiday and all, that it will be OK to drive for a little while until he gets around to fixing it.
