How do you blow a engine turbo.
There are several ways to blow up a cars engine. If your car loses all its oil and you don't shut off the engine you could blow it. You could blow it by over revving the engine for long periods of time. If the engine doesn't have water in it it could run hot and quit.
Blow by is caused by internal engine problems. You need a new engine.
The engine blow by is exhaust gasses trough out the breather pipe
Normally they blow due to engine overheating. They can sometimes blow for no apparent reason.
Engine oil coming from breather pipe
run out of oil
"Blow-by" is not good for any engine. It indicates worn internal engine parts (rings)
Let the engine overheat will normally blow the head gasket.
Get a new one.
Replace the engine or have it rebuilt. Once an engine is worn to the point that it has excessive blow by, those are the only real solutions. You could try using a heavier engine oil, but the effect that will have is negligible.
ofcourse they do, they blow on any engine
