I have a problem with my mercedes c230 kompressor recently had major job on engine due to tensioner failing and smashing valves. Now the problem I have is that before and after I had this job repaired (head done, valves repalced, water pump, new chains, decoked, piston rings, etc) I was losing alot of oil. basically I would fill to about maximum and then drive. 250 miles latter oil has leaked from engine. there are slight puffs of black smoke from the exhaust, but the mechanic cannot figure it out and he says there are no leaks. Help.
I still have not found an answer.
What happens if I close the question, do I get a full refund.
What do you mean by engine breathing, and when you say intake can you be a bit more spcific.
Is combustion chamber leakdown test somthing most garges can carry out or somthing that mercedes themslves do.
Given that you say that the engine will still consume oil, do you think that drinking 4-5 liters of oil within 250 miles is very excessive.
