does anybodies 330ci go through oil like water?
what year? and are there any leaks or smoke issues with the engine
2001 year, have it looked at numerous times and there doesnt seem to be any faults or leaks. It just burns alot of oil for some reason
first look at replacing the breather system, if it blocks it pumps oil into the manifold where it is burnt during combustion. after that you may need to check the valve stem seals using a borascope down the plugs. if its valves, a rebuild of the head may be necessary
