Did an oil change on my XJ tonight, and thought I'd have a look at the air filter while I was at it (was gonna replace it tomorrow). Filter was nothing too dirty apart from the oil thats been dripping from the breather from the front of the valve cover!
The rear valve cover breather (PCV?) is also split and came apart in my hand. From what I can gather, this should be under vacuum, but obviously isn't.
Is the fix as simple as to replace the rear breather pipe, or could it be something else?
