Hi guys,

I have noticed many people on internet were looking at how to change the PCV valve on E36 4 Cylinders engines.
So I decided to change mine because the hose were broken and my car is 15 years old, so it would only make things better.

Tools and parts needed:
- Allen key, size 5.
- WD 40 to grease the screws a bit before you put them back
- New PCV valve
- New hose

Step 1: Remove the hose from the engine and PCV valve. No screw, easy to remove.

Other steps are detailed below.

So there you go, here is some screenshots to help you out. HTH.

Picture 1. Shows the only tool you need really if everything goes fine.

Picture 2. Shows the valve, a little bit broken here, as I one of the two screw was seized. So I had to break the top of the valve and burn a bit to access the screw. Removing the oil stick screw is very useful too, as it gives you more toom to work.

Pictures 3 and 4. Shows the screw that hold the valve. There is 2 of them only, on each side beneath the unit. Easy to spot.

Picture 5. Shows the unscrewing operation. I have shown the screws first so you know how it looks like.

Pictures 6 and 7. Shows the unscrewing operation again once I have melted enough to remove the valve itself, this screw on the right side was seized, so I had to burn.

Picture 8. A bit of greasing will not hurt See the picture of the new valve too…

Picture 9. Ok last step, put everything back together and you are sorted. Make sure you do not forget to reconnect the new hose and that everything feels strong and fits properly.
