THe PCV valve is on the intake manifold on the bank of the V of the engine facing the firewall, not the part of the V facing the radiator. It is toward the right hand side.

Another source of vaccuum is the brake booster hose. Be sure to re-attach the hose once you've used it to pull the cleaning chemicals into the motor.. If you don't you'll have no BRAKES!

If you are not sure of what you are doing and have never done this before, follow Matt's advice: look in your service manual or go to a mechanic. Changing the PCV valve is not difficult at all, and using it as a point of vaccuum is not difficult either, but be sure to always work on a car after you've read all the possible instructions. If you are not confident in what you are doing, you can do more harm than good, so ask help from an experienced buddy to help you as you learn.

Seeing how you guys are talking about it, I still haven't located the PCV valve on my newly acquired 93 SE. As much as I look for it, I can't find the thing. I read in my Haynes that it's where you stated it was, coming out of the firewall-side valve cover; I guess I have to get a flashlight in there or something to see it. Am I looking for a standard PCV- it twists out from a rubber grommet, no tools needed, rattles when you shake it, etc?
