E63 650i - PCV Valve
Discussion
Ok so firstly a bit of background.
Bought the 650 8 weeks ago. Drives like a dream. No engine warning lights and no smoke.
Sitting at temp traffic lights last Monday for what felt like forever, drove off and left a huge blue plume behind me Oh No ! Some quick googling ensued and the common thoughts were split PCV valve or valve stem oil seals.
Sunday I set about exploring the PCV valves and low and behold one had a 2" split and the inside was thick with oil and gunk. Replaced both PCV valves with genuine BMW parts on Monday morning.
Car drives perfectly, no smoke, leave it idling for 90 secs and you start to see the smoke appear and build up.
General consensus is that there is still oil in the breather \intake manifold and will take time to burn off. So far I've done 120 miles and when idling after a short period the smoke again still appearing and building up. Am I expecting too much too soon and should I just drive it a few days \ a week and ignore the smoke for now ?
No smoke on cold start
No smoke on driving 5mph to 80 mph
No smoke cruising then hitting kick down
Smoke build up after 1.5 - 2 mins
