Bad piston rings. Get new engine.
too much fuel, excessive oil consumption
engine burning oil
Float needle sticks in carb and allows excess fuel to seep past rings into oil.
This can happen on a high compression engine (especially diesel) when the oil is not changed often enough. The fuel blow-by from the rings causes fuel to mix with the oil and "coke up" , creating oil that looks almost like asphalt.
blue smoke is oil. white smoke is water. black smoke is unburnt fuel
the engine is burning oil. blue smoke oil white smoke antifreeze black smoke excess fuel
yes
When engine oil leaks past the turbo seal it can collect in the innercooler. This collected oil then can be sucked into the engine and burns as fuel. This uncontrolled oil that has now being burnt as fuel causes uncontrolled revs of the engine resulting in over rev of the engine. Since the oil is not metered by the fuel system, turning the ignition key off has no effect on stopping the engine and the engine will continue to run uncontrolled until the oil source is consumed or the engine fails. The only way to try and stop this over rev on collected oil is to cut off the air to the engine. Cloth towels, shirts or any other cloth like material placed over or into the air intake to shut off all air to the engine can work.
The injection system has a tiny air leak that causes the system to not work correctly until the air is purged from the injectors. Look for a tiny fuel leak near and injector or an increase in engine oil level that will show fuel contamination in the oil
That is the engine running too lean (lack of fuel). This condition will lead to overheating and failure of the engine. i think it is because the lubricating oil in the cylinder is burned with the fuel.
You either have a bad float or/and bad needle and seat, which is causing the carburetor to flood. The fuel then flows through the valves and piston and mixes with the oil. The diluted oil will not lubercate and you will sieze the engine.( Not good!)
Engine oil does not cause a engine knock. It is caused by pre-ignition, which can have many causes, including the wrong grade of fuel octane. Make sure that you are choosing the correct fuel for your vehicle. You may want to take the vehicle to a mechanic, as engine knocking can seriously damage your engine.
