3.0d plumes of smoke

My X5 recently started smoking on my way to work, I had it recovered and was told to replace the OSV. After replacing it and carrying out an oil service it is still smoking a lot. Can anyone advise any possible causes?

I checked and the coolant was slightly low but only took about 200ml.

I've tried k seal today. Ran it at idle and it's still smokey. Blipped the throttle and it has blown a lot of oil onto my driveway.

diesel engine problems
With an ASE-certified master mechanic on staff, we get all sorts of questions about gas and diesel engine problems. Some of them are pretty general and hard to diagnose through a quick conversation. Not that we aim to be able to do that for everyone, but it's nice when we're able to shed some light on a problem that makes another person feel more confident in being able to go out and make the right decisions in solving their problems.

"Black smoke" is one of those general symptoms that seems to indicate a problem, but which bears further investigation to figure out what the cause is. Really, any smoke would fall into this category. Because you've not just got black smoke, there's also white diesel smoke and even blue diesel smoke. So let's do a quick rundown of what to suspect what you've got diesel smoke where it shouldn't be.

Black Smoke - this is the most common one and is really just an imbalance in the air to fuel ratio - too much fuel to not enough air. This means either too much fuel is being added to the mix or there's not enough oxygen being supplied to burn the fuel. The black smoke is full of particulates that are basically large diesel particles that normally would be burned as fuel. Any way you look at it, a diesel truck emitting black smoke is not going to be getting the optimal fuel mileage it should be getting.

Most common causes of black smoke are faulty injectors, a faulty injector pump, a bad air filter (causing not enough oxygen to be supplied), a bad EGR valve (causing the valves to clog) or even a bad turbocharger. Some of these are easy fixes.

White Smoke - white smoke means that the fuel that is being injected into the combustion chamber is not being burned properly. The common causes that produce white smoke range from something as simple as low engine compression or water in the fuel to the fuel pump timing being thrown off because something is starving the fuel from getting to the pump in the manner necessary for the pump to time and work correctly.

Blue Smoke - blue smoke results from burning engine oil. This is a mechanical problem because engine oil isn't supposed to be getting into areas where it can be burned. There could be a faulty injector pump or lift pump, which would allow oil to mix with fuel and be burned. The valves or valve stem seals could be bad. Worn cylinders and piston rings (X-tra Lube can help with this problem) allows oil to seep where it shouldn't. Or you could have a problem as simple as having put too much oil in the engine.
