Oil filler cap

Post by gs.davies »

What’s the correct oil filler cap for a car fitted with a PCV valve? Vented or non-vented?

Cheers

12A402 comes back as non vented - should it be the one with a load of wire wool in the top?

My mistake my old parts book shows 12a 402 as the vented one but looking at newer sites the correct cap is GFE6003. GFE6003 should be the one with gauze in it.
