On these cars it's more of a system than just a valve. This will walk you through it.

Where is the pcv valve on volvo s60 2.0T 2002

The PCV ( Positive Crankcase Ventilator ) valve is located in a valve cover. It is identifiable by the largish hose ( usually about 1/2 - 3/4 inch diameter )going from it to the intake system. If you have a throttle body injection system, the PCV hose will go to the throttle body. Typically PCVs are on the passenger side of the motor.

Where is the pvc valve on a 2008 volvo v50

There is no PCV Valve, there is a Flame Trap System underneath the Intake Plenum on the front side of the Block. These are made of plastic and get plugged up, crack, and the plastic Vacuum lines fail. IPD carries the entire system. You will have to remove the Intake Plenum so you will need a gasket for that as well.

Volvo v70 vacuum diagram

I take it you did not replace the PCV System. I would almost guarantee that you have a massive vacuum leak in that system. IPD has it for sale on their website and show a picture of the system outside the engine compartment so you will know what to look for. You will have to pull the Manifold again to do it.

Replace front crankshaft seal

When you replaced the front seal did you smear a bit of oil in side of the seal because sometimes if you don't you can nick the inner seal.
if the seal is ok the you most probably have a worn crank/cam shaft.
hope this helps

How do i change the pcv valve on my 2004 volvo s40? and where is it located?

    Turn the Volvo 850 off and allow the engine and its components to cool for 30 minutes.

  • 2

    Open the hood of the Volvo 850 by pressing the hood release button within the vehicle. Locate the PCV valve; the valve is identified as a small rubber valve located on the engine crankcase. You will also notice a small hose sticking out of the end of the valve. If needed, read the Volvo 850 owner's manual for more information.

  • Disconnect the hose from the valve by pulling the hose out of the valve. The hose will come off the valve with minimal force.

    Turn on the engine of the Volvo 850. Place your finger over the hole in the valve where the hose was connected. If you feel a strong suction, the valve is working properly and fine. If you do not feel a strong suction, the valve may be clogged and needs replacing.

  • 5

    Turn off the engine of the Volvo 850. Use needle-nose pliers and grip the valve. Pull the valve off of the crankcase.

  • 6

    Install a new valve by putting the valve in place on the crankcase. Insert the hose into the new PCV valve. Secure the new valve in place by pushing it down until it locks into place. Close the hood of the Volvo; pull up on the hood to ensure the hood is shut properly.

    Where is the pcv valve located on a 1998 c70

    There isnt' one. Volvos are equipped with vent-box located underneath the intake manifold. Remove the oil dip stick tube and then the intake manifold and remove the box. Install a new breather box and make sure to clean the lines going to and from the box. If the breather box gets clogged, oil will push from the oil filler cap, dip stick tube and worst case, blow through the engine seals.

    It has a flame trap, no PCV valve per say. On your air inlet tube come from the throttle housing you'll see it. Disconnect the hose from throttle and air box.

    98 Volvo V70 Turbo engine oil leak

    It may be the gromet for the PCV valve or it could be the spark plug rubber seal located in the valve cover if it is the type of engine that has the wires and spark plugs that go down through the valve cover, if this is the case buy a valve cover gasket with the rubber gromets that are located around the base of the hole where spark plugs fit through and install.
