Quick question
V70 D5 series 2 2007 with 207k on the clock
Slight crankcase pressure (rubber glove test) and oil disappearing (into DPF I think). I have replaced the PCV diaphragm which was distorted and cleaned out the pipe work leading from there to the EGR but. It taken the EGR off and cleaned it out. Would a clogged EGR cause crankcase pressure?

I'll give it a try. What would this test show? I put the rubber glove over the oil filler to get a slight positive pressure. My first post should have read that I haven't cleaned out the EGR yet, only the adjacent pipework.

well if there is a lot of fumes under pressure coming out it would indicate combustion gas leaking past pistons into the sump, highly unlikely though unless you have an expensive fault. the egr wont affect that.
