Was riding on the M4 heading West towards Heathrow Airport and a cloud of smoke appeared, pulled over behind the car that was smoking as I didn't really want to ride past it inhaling in all that smoke.After a couple of seconds I remembered watching a video on LiveLeak that looked similar and tried to help. Unfortunately the guy didn't know where his air filter was and whilst I was in there looking a coolant hose failed and sprayed all over me so I stopped looking any further, engine seized up on its own soon after that.I have since looked up other ways to stop this, if it was a manual gearbox I could have put it in a high gear with the brakes applied and dumped the clutch to stall the engine, didn't know this at the time so I don't know if it was a manual or automatic.This is caused by a faulty seal, usually at the Turbo, which lets engine oil into the combustion chamber and the engine runs on the oil, it is not diesel that is burning to make the engine run. Eventually all the oil is used and the engine gets so hot it seizes solid.For licensing/usage please contact: licensing@liveleak.com
