Essentially what happens on the Defender 90 with the PCV, which is positive crankcase ventilation, restricted vacuum, due to the oil separator is going to create vacuum in the engine.
Also, down in the crankcase area and up in the valve covers. At the top, you need a breather, so that there's a flow of fresh air running through the crankcase to alleviate any corrosive gases that build up and crankcase pressure.
Watch Doug, our Land Rover Master Technician, go over the steps involved in performing the PCV Tune-Up Service on a 1997 Defender 90. The service also applies to Land Rover Discovery I and Range Rover P38 (GEMS Engine vehicles - see fitment years.)
Using our money-saving PCV kit # 9205G, with everything you need to do this service, it is recommended that the PCV system be replaced every 30,000 miles.

Why did you choose this rating? ...cuz deserves it. What did you like or dislike about the product? ...felt not as sturdy as the one I took out, and gave me a bit of trouble putting it in. A good tap a couple times once align in the tube, will get it in. Would you recommend this product to others? ...yes.
