2004 4.4i X5 Oil and Smoke issues.

[zazoo]

Noticed white smoke while I was in traffic from the right side Exhaust of my X5 which stopped when I drove off on the freeway. 2 weeks later I get a check Oil Level flashing at me and had to top up with nearly 4 litres before I got it back on the dipstick level again.

Its been 2 months now and I get the Check Oil Level Light again with smoke also and when I checked the oil I was so low I had to put in another 3 litres after driving only 1000miles.

The white smoke from the exhaust is more now and has a distinctive smell. I checked both breather valves and they look OK with the gaskets still new also looked at the CCV today with a friend and they look clean and OK with a little bit of sludge but that looks normal.

I am so worried and need help Guys, the car is a 2004 4.4i X5 with 81000miles on it and I live and work in west africa with not very reliable mechanics and need to have an idea of what to check before I get into their scary hands. Any advise and ideas would be appreciated please

do you notice any leaks on the ground after it sits for awhile. if you do get under there with out moving the car and see if you can trace it. if not the I would lean towrds bad valve seals or piston rings

No Leaks found when It sits for a while. Parked in own Garage and been monitoring for leaks for some months and none found.

Ok...decided to change oil and oil filter next week and get it serviced. Currently I use Castrol 5W-30 Magnatec but have been advised to use a thicker oil cos of the extremely high temperatures around here, will see if that helps.

Does anyone have a picture of the location of the OSV Valve on N62 engines.

Thanks
