Can Turbo cause Blowby?
Anyway, if the seals are out in the turbo the boost pressure or exhaust gases from the turbo can get into the oil return to the crankcase inturn causing blow by.
What does excessive blow by mean?
When you combine a large cylinder bore, high cylinder pressure through turbocharging, many hours of use and marginal maintenance, excessive blowby is the result. The leakage of any combustion gases, air, or pressure into the engine’s crankcase is considered blowby.
Can a bad turbo cause high crankcase pressure?
The intake manifold is under pressure during most running conditions when an engine is turbocharged. The gas and oil bypassing the rings are still present, and the pressure generated by the turbocharger can increase crankcase pressures.
How do you test for excessive blow-by?
However, one of the tell-tale signs of excessive blow-by is white smoke billowing from the oil-fill tube or opening on a valve cover. To check this, set the oil-filler cap upside down on the tube or opening. If it immediately blows off, there definitely is too much crankcase pressure.
