Is your PCV clogged up?

Pvc Valve


I can't locate PVC valve on my 99 grand am 2.4 liter. Were is it located


PCV or ENGINE OIL SEPERATOR as called on the 2.4l has had a few different locations and depending on the vin and engine is the only way to know for sure where its at, look up the part on a site like rockauto so you know what it looks like as its not the normal looking one from days long gone. Some are on the right drivers side of engine block and some have them on the passenger side firewall side of engine, but if you know what it looks like you should be able to locate it as it has two hose nipples and about five bolts holding on.
