I've been getting awful MPG recently and have noticed that if I remove my oil filter cap whilst idling the cap is hard to remove, once I get it off the engine is sucking air in via the oil filter cap and the revs rise.
Is this normal? I think I may have a knackered PCV valve. Is it a DIY replacement job?
