Yes there is a PCV valve. The PCV valve on GM 3.8 liter engines in on the passenger side of the car upper plenum in a well or compartment. This well has a pressure sensor on top of a 1/4 turn cover.Under this cover maybe a spring and two o-rings one on the cover & one on the PCV valve itself.Be careful don't break the pressure sensor, it also has a seal that fits into the PCV cover. The 3300 is a smaller version of the Buick 231, AKA 3800. The 3800 has no PCV valve. I could not find it either on my girlfriend's old Olds 3300. I think it's safe to assume that it simply doesn't have one. Go to a parts store and ask them to look up one. I'll bet they won't have it. The PCV valve sucks crankcase gases into the intake where they can be combusted. The valve itself protects the crankcase from becoming pressureized in the case of backfire which could cause lots of bad stuff. I'm assuming that the 3800 has enough crankcase "ventilation" where this wouldn't be a problem.
Some of the 2000 models have a PCV valve on the back of the valve cover. The other models do not have a PCV valve, but use an oil/air separator instead.
PCV Valve is located near front of hood on the engine block between the fuel injectors.
Remove the vacuum hose from your 1989 Oldsmobile 3.8 liter engine PCV valve. Remove the retaining bolts from the valve. Reverse the process to install the new PCV valve.
it is locatated to at the right side rear of motor, next to the throttle body and the IAC valve, and tps sensor.
if you have a 2.0 spi motor its in the corner of the valve cover. does not look like a old style pcv valve
The pcv valve should be located on the top of the valve cover. It is located closer to the rear of the motor.
The PCV valve is located in the rocker cover (valve cover) Once you locate it pull up on the hose that is connected to it. Remove the PCV valve and put new one in. Reinstall in rocker cover.
THERE IS NOT ONE.
The pcv valve is located in the valve cover on the top of the motor. It has a black hose connecting it to the intake manifold.
Generally you will find a PCV valve somewhere on one of the valve covers, with a hose the connects to it.
Pass side valve cover.
on the 3.4L V6 it is located on the front valve cover, just to the right of the oil filler cap. there is a hose with a 90 degree boot on it. remove that and pull out the PCV valve.
Do you mean the PCV (Positive Crankcase Ventilation) valve? The PCV valve should be on the top of the motor, either in one of the valve covers or in the coverplate on top of the block.
The PCV valve on a Dodge Ram 1500 5.7 is located in the air filter hose that goes from the air filter to the motor. On any vehicle, the PCV valve can be located by starting at the air filter and going to the end of the connecting hose at the motor.
PCV IS ON LEFT SIDE VALVE COVER TOWARDS THE FRONT IF YOUR FACING THE MOTOR
PCV valve should be on bottom right side of motor. to the right of the last spark plug. Pull it out with car off. It comes out with a hose on it. Insert new PCV valve into hose. Insert PCV into open hole.
It's on the passenger side of the motor under the valve cover.
On top passneger side of motor. look behind the alternator inside the space down a little. was a pain to remove for me. On some models the PCV valve is located in the valve cover. A hose runs from the valve to the throttle body base plate or intake manifold. On other models, the valve plugs into the intake manifold and is connected to the valve cover by a hose.
its in back valve cover at fire wall i removed the plenum from the intake manifold to get at it.
It's going to be off the valve cover(s) one or the other. Plugged right into it.
front side of plastic intake manifold
One possible cause is a blocked PCV (positive crankcase ventilation) valve. As your motor is running the crankcase will build with pressure and the PCV system will let the motor breathe. If the PCV valve is blocked or faulty then the motor will look to release the pressure somewhere else.
on the back side of motor by firewall
on top of the motor
