It seems to me that a mechanic who knows X5 BMWs could give you a more accurate diagnosis. Your guy has named everything it most likely could be. My first suggestion is to check another mechanic.

You say you see smoke both under the hood and coming out of the exhaust. Obviously, smoke coming out of the exhaust had to come from the combustion chamber. That could come from oil leaking through the valve seals or the pistons or from oil leaking from the oil cooled turbos into the air intake. Smoke under the hood suggests an oil leak not associated with combustion touching something hot enough to smoke. Since you have both, it sounds like a leak associated with the oil cooling system on the turbos.

Hopefully, it is only a hose.



The valve stems are not a major problem as long as you keep the oil level up. You could easily burn up turbo bearings if the oil cooling system is leaking.

Good luck

Sounds like the current BMW campaign for the VCS! I'd suggest taking the vehicle to BMW for inspection & diagnosis and not an independent repair shop. BMW is covering vehicles provided the current owner has owned the vehicle for the past 6 months. You might still go through hoops depending on the dealership but it's definitely worth it. The job is about $8k!

I would disagree with the statement that the valve stems are not a major problem if you keep your oil level high. If the seals are done they're done and oil will pass out the exhaust as blue smoke.

I think he is saying that burning oil isnt a risk as long as you dont let the oil level run too low.

Not that keeping the oil level high will change valve stem smoking...

I think
