Nope, no smoke on take off from a stop (short or extended wait). Re-ringing or re-building is an option but not this year (gotta pay for a wedding!). For now I'm just living with it. To do anything with this engine aside from a simple valve cover gasket, the engine has to come out. There is no...

Originally Posted By: vinu_neuro UOA's are irrelevant at this point since the oil control rings are either defective from the factory or already worn. Is the car out of warranty? If so, push for an oil consumption test and a replacement engine. If it is, go after the dealer to buy it back since...

Originally Posted By: SL8R If you're going to try this, make sure that you add water very slowly (a spray bottle works great) so that you don't accidently hydro-lock your engine. Good idea. I remember reading about using a spray bottle to minimize the risk of hydro-locking the engine.

Yup, I've heard of the water decarb method. I plan on giving that a try soon.

Yeah, I doubt the dealer knew about it. I got the service records from the Audi dealer where he serviced it (same dealer network as the BMW dealer)...my guess is he just dealt with the oil since he never had it on record.

Originally Posted By: dparm I wouldn't sweat anything yet. I have the same car and my UOAs hav been consistent, and that's what we want. Consumption is likely a byproduct of hard driving (though even during race season my car only consumes about 1qt every 5k). Don't run the Syntec 5w40 again...

Originally Posted By: addyguy If it's been driven really hard, the rings are worn, pure and simple. During the summer, I'd try a 50wt., just to see what happens - 15W-50, 5W-50, 20W-50....just to see if viscosity is the only thing that changes it. Yeah, I have no idea how the PO drove it. I'm...
