Is it the 'check valves' that can be replaced without the crankcase cover? Think I've seen these on another post, do they unscrew from the pcv system?

When I spoke to woods today Mike said the pcv system was one complete system that was all part of the crankcase cover but I was sure the 2 check valves are separate parts, confused!!

I'm using 1/4 litre evey 2k which is pretty normal I rekon. As I said I don't think it's valve seals as they were replaced recently, so its turbos or pcv system.

How is it possible for the pcv system to cause a puff of blue/white smoke on cold starts? Can anyone explain?

Will check out the RB pcv thread.
