Does anyone know what happens to a car when the PCV valve goes bad? I've talked to several Honda techs about replacing it for GP and most of them say "Don't worry about it. It hardly ever goes bad, but when it does, you will know it."

So what will the symptoms be? Anyone with any experience with a faulty PCV valve?

 

usually get worse gas mileage...easy way to check is just to pull the PCV and shake it...if you dont hear the lil ball rattle inside than go grab a new one for two bucks and throw it in...

 

h: Thank you!! :thumbup:

 

Not to sound stupid or anything but what is your pcv valve and where is it located?

 

i think it is on top of your valve cover.

 

You'll mostly notice a decrease in gas mileage and you might even be burning oil. PVC stands for positive crankcase ventilation. The pcv valve is located on the intake manifold. It's purpose is basically to regulate fumes from the crankcase to the intake manifold where they can be burned otherise the fumes would blow seals and stuff in the crankcase and then the fumes would just go into the atmosphere. That's a purpose of the pvc system. I can't really explain more about but thats all I know. But don't neglect the pcv system as it can cause huge problems in the long run. I think it also prevents a little blow-by and sludge. It's a pretty critical system.

 

got some pics of it?

 

It's on the back bottom of the Intake Manifold, right above where the oil filter goes.

 

im still a newb at sohc motors, im used to my teg motor.

 

it is on top of the intake mani on every b series motor except the gsr.
