Hi, Your PCV may be clogged, but the chance are the you have blow by. This is crankcase pressure making it into the head, meaning that you have issues with your piston rings. the rings are either broken or gummed up. If your PCV is clean, run SeaFoam or an equivalent product. If this doesn't work, it's broken rings.
PCV valve is located in the valve cover. start engine, allow to idle. disconnect pcv valve from valve cover and feel for vaccum. If you feel vaccum good, if not trouble shoot system. Pcv valve dirty, hose clogged or cracked, etc. check the rubber grommet in valve cover for deteriation, replace if necessary. if the old pcv valve is clogged the the hose may be as well, clean w/ solvent. install new valve and reconnect.
The engine will have difficulty in performing correctly!!
pcv system is clogged up.
I'm not a mechanic/technician but I believe your PCV valve or PCV hose may be clogged - something to check (Helpfull)
You cannot clean it. If it is clogged it must be replaced.
easiest way to check pcv is to pull it out of where it is and shake it if it rattles, it is good. if it does not rattle it is clogged up and needs replacing
Probably the same place that the pcv valve is located on my 1990 Lincoln town car with 302V8 and fuel injection(Rear middle of lower intake manifold.....can't see it because of upper plennum). If there is a metal screen under the pcv valve, you better remove it before it becomes clogged.......it WILL become clogged eventually!
pore strips
Yes, you can clean the PCV valve. Take off the PCV valve and get a spray can of carb cleaner. Just spray into the valve and just enough to clean out any gunk that might be in there. You should hear it rattle when you shake the valve.
no
clean out the jets and any other holes that are clogged
