What causes Blowby in diesel engines?
What causes Blowby in diesel engines?
Blowby is the leakage of any combustion gases or pressure into the engine’s crankcase. Most blowby occurs when exhaust gas enters the crankcase by going past the piston rings while other sources include turbochargers.
Can a cat engine still run after a blowby?
Performance, oil control and blowby control quickly returned to normal. At 900,000 km, the engine was still running sweater than ever, and no oil consumption. His Cat engines are also running better, and the oil in them stays very clean right to the change interval.
What causes a Caterpillar engine to blow by?
One of the ways to check if blow-by is too great is to put your oil filler cap upside down on the filler hole. If the cap gets blown off, there is too much pressure in the crank case. Blow-by can be caused from piston rings that are worn out. A cylinder with worn out rings will have low compression and will likely cause a misfire.
What causes a caterpillar to blow by the filler cap?
This is because the combustion pressure is just too great for the piston rings to hold completely. Excessive blow-by can caused by piston rings that are sticking in the bore. One of the ways to check if blow-by is too great is to put your oil filler cap upside down on the filler hole.
How does a worn piston cause blow by?
Worn pistons cause blow by. Just as the cylinder walls wear out and the bore becomes bigger, the piston becomes worn and becomes slightly smaller. Bear in mind that aluminum is a soft metal, and grit accumulation in the combustion chamber carves grooves into the piston.

Can a bad Turbo cause a blow by?
Yes, I have seen turbos cause blow-by. Measure your blow-by then remove the oil drain hose from the turbo and run it into a pail and measure your blow-by again. That will answer your question.
What causes a caterpillar crank to blow by?
Excessive blow-by can caused by piston rings that are sticking in the bore. One of the ways to check if blow-by is too great is to put your oil filler cap upside down on the filler hole. If the cap gets blown off, there is too much pressure in the crank case.
