That means its burning oil valve seals are going bad that a repair shop work buddy. but some one told me put some brake fluid in the oil let it run for half hour then drain the oil and fill it up with new oil. it will get few days before it gets better. (not recommended)

SOURCE: taking the front door panel off my 525 bmw

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

SOURCE: BMW 318ci 2003 Blue Smoke When Engine is Warm

you definitley seem to be getting oil in your combustiion chamber, pull your spark plugs and see if they are coverd in oil. if so your valve seals are bad, if not your piston rings are bad. As far as the kncking noise its hard to tell though a description, id have to hear it, but ill go out on a limb and say its in relation to the leak it could be a piston or valve knock. The garage heard the noise, ididnt so i hope i could help.

I have bmw 525 diesel. I see excess white smoke


white smoke from a diesel is usually lack of fuel, black smoke is to much fuel, check your fuel filters for restriction. this is providing that the smoke is not coolant in the exhaust but if that's the case it should be overheating. also if it is cold were you are you might have a fuel gelling problem that will also cause white smoke. just put some anti-gel in the fuel and see if the problem goes away.

1997 Saturn SL1 very hard to start


jlwhelen,
I will suggest that perhaps the blue smoke is not purely oil. It sounds like you may have an ignition problem where the engine has a hard time firing until warmed. The blue smoke may be, at least in part, unspent fuel. I realize that a warm engine that uses oil will smoke blue, but excessively rich conditions on startup can result in a similar effect. If the choke circuit is delivering a little extra fuel from a dirty injector, the problem may be worse when starting from cold.
To remedy this, I would suggest a simple replacement of plugs and wires, as well as a fuel injector cleaner through the tank. I would bet money that these simple maintenance points would solve your problem.

Good luck!
Lucky

Nissan 300zx starts smoking when reaches tempture


sounds like your rings are leaking oil into the cylinder.. causes blue smoke. would not do it until it is warm due to the higher viscosity of the oil at cold. try some ring seal and see if that reduces it.
