What causes engine oil to blow by into the air filter box?
If any cylinder tests low squirt a small amount of oil or transmission fluid into the corresponding spark plug hole and perform the test again.

What causes the oil to blow by in a diesel engine?
Causes of Diesel Engine Oil Blow By. by Tony Oldhand. In a diesel engine, blow by is defined as the compressed fuel/air mixture in the combustion chamber leaking past the piston and entering the crankcase. Blow by is not good since it robs engine power and builds up gas pressure in the crankcase.
What does excessive oil out blow by tube mean?
Two are 2001’s and one is an 2002 and all of them have acsesive oil on the front from the oil overflow or blow by tube, or whatever it is called, but I was under the impression it was normal. Am I wrong? And please termanology that idiots like me can understand.

Where does the blowby come from in a diesel engine?
Under full load, the blowby may be 2.7 cfm. The remaining 40% of blowby comes from sources that most do not consider, such as the turbocharger or the compressor for the air brakes on a truck. When diagnosing an excessive blowby condition, you need to look at any components on the engine that are linked to engine oil and, thus, the crankcase.

What happens when oil is mixed with blow by?
Mixed by a spinning crankshaft, combustion by-products churn with partially vaporized oil in a witch’s brew that, if not properly vented and managed, can be problematic. Windage is also involved in any discussion regarding crankcase pressure since oil is the viscous fluid that we must deal with.
Is there smoke coming out of the breather tube?
The thing still sounds and runs normal, EGT and boost are normal, oil pressure and water temp also normal and no abnormal smoke. WTF is going on here?? At idle, I can actually feel a breeze coming out of the breather tube, but there’s hardly any white blowby haze to it that we’re all familiar with.
