Questions on belt and PCV valve

I got my wife to pick up a belt for me at Advance Auto last night. I don't need to replace my belt, yet, I just wanted to have a spare. Well the belt she picked up has ridges where it would contact the alt. etc. The one in rhe Samurai now is smooth on that side. Would the replacement belt work, with the ridges or should I find a smooth one?

I replaced my PCV valve the other day, with a deep socket, ext. arm and a little prayer. Went in and out fine. My question is what does the PCV do? I know it is a filter and Sarge had posted if it not replaced it can cause the oil to force its way out of the seals.

Like I say I know enough to be dangerous, that is why I always ask first.

Thanks for the info.

Marc

Re: Questions on belt and PCV valve

The belt will work fine, thats how that brand makes them.
When the engine is running, a certain amount of the compression being created in the cylinders will get by the piston rings into the crankcase. This would pressurize the crankcase if there was no vent. The seals are not designed for this pressure so one of them will "let go" to vent the case, causing an oil leak. The PVC allows this pressure to bleed off back into the air induction system

Re: Questions on belt and PCV valve

zooky is right, the function is in the name:

Positive
Crankcase
Ventilation

It serves another minor purpose in that it sends that vented ouut compression back through the intake so any residual fuel vapor or whatever gets burned up and doesn't go into the air or end up in your oil..
