I drove into the local Jiffy Lube today to get my car serviced. Since it had 101,000 miles on it, I thought I'd get the pcv valve replaced since I was driving around with the factory original.
The blonde girl that logged me into their system came back and told me that my car didn't have one! Is this possible? Thanks.
The prices for those things sure have gone up. I remember when they was nienty seven cents, or less. I spritz some carburetor cleaner in mine and shake it and put it back on there.
This topic got me interested, and I did some reading:

Points of note:
So before the PCV was invented, internal combustion engines mostly used som ething called a "road draft tube." It used the slipstream when moving to d raw air out of the crankcase (you can immediately see the problem when the vehicle wasn't moving). This had the unfortunate side effect of dumping un burned hydrocarbons (from cylinder blow-by) straight to the atmosphere, and was a major source of smog.
The PCV was originally invented for tanks, so they could ford rivers etc. w ithout water getting in the crankcase. It also had the benefits of reducin g emissions, and keeping the inside of the crankcase cleaner. Use in autom obiles took off in the 1960s, with California requiring it from the 1961 mo del year.
So anyone who tells you a modern internal combustion engine doesn't have so me kind of PCV valve or similar crankcase ventilation setup, probably doesn 't know what they're talking about. The EPA would not be amused, to say th e least.

This morning on my way to the food store I saw a different kind of blow by. That blue smoke coming out of the tail pipe of that pickup truck. It looke d like it was fogging the whole neighborhood.
