Turbo Diesel Engines

The blow-by gases and crankcase vapors flow through the hose connection on cylinder head cover to intake line in front of compressor. Together with intake air, they are drawn into the combustion chambers. A by-pass line, located between clean air end of air filter and breather line enables the compressor to draw up clean air at high speeds along with blow-by gases and crankcase vapors. The additional intake of clean air will restrict the vacuum in crankcase.
