On a 1993 Buick Regal 3.1L, the PCV valve is located on the intake manifold. It is situated underneath the MAP sensor.
I have the same issue it is the map sensor
That is 31,000 ml
THE CRANK SENSOR IS LOCATED ON THE PASSINGER SIDE OF THE ENGINE , BUT ON THE BACK OF THE ENGINE YOU MMUST REMOVE THE FRONT TIRE TO REACH IT RIGHT BEYOND THE SPEED SENSOR No it's not! It is located between the transmission and the engine block above the oil pan on the rear(since the engine is sideways)just about the middle of the car. It has one bolt holding it in and it is a little hard to get out, careful not to break the bolt
31L is 310 deciliters.
depends on the age and quality
The PCV valve is located on the back valve cover by the firewall, you will need to remove the strut brace to get at it. The hose runs from the valve to the rear of the intake plenum and it is very stiff, follow it down to the valve cover and pull straight up. It is very difficult to remove due to the lack of room and the fact that the hose is not flexible. if the hose is stiff replace it that's is from the motor runing at 220 degrees all the hoses go bad quick when they run that hot
hahaha.... bleeh bio 31L bro?
On the bottom of the motor.
