Help! Blue smoke from exhaust

Saw this problem on the forum a couple of years ago on an Ed30. He replaced his rear PCV and it cured the fault. Can't seem to find the thread though

Thanks, I've taken it out again this morning with the standard PCV and no sign of smoke so fingers crossed it was the BSH revamp that was at fault. I've also cleaned all the oil from the engine bay and am going to take it for a longer drive this afternoon to make sure that it's not still coming out of the filler cap, as it was doing that before it started smoking.

Just to update this again, I've done about 70 miles this afternoon and no more smoke. Thankfully a simple fix!

Just shows that these "PCV FIX" and "PCV REVAMP" just aren't worth it. They just seem to cause problems. . .

Yup! Like I said, the previous owner fitted them. Thankfully I got the standards parts/pipework from him when I collected the car. I certainly won't be recommending them to anyone any time soon.

Sorry to drag an oldie up, been thinking of blanking mine off and been reading loads and loads and loads...... but don't think I am going to now.  I am going to get a stage 1 remap soon so was looking at options.  If anything I would just get one of the the newer revised OEM jobbies :)

Stick to the latest revision OEM valve

Or do away with the PCV system entirely and vent both cam and crankcase to atmosphere.

The PCV 'revamp' is a half fix that removes one potentially problematic valve by halving the breathing capacity of the engine, severely restricting it when the engine is under vacuum in comparison with the factory setup.
