Why does the oil blow out of the crankcase?
Bear in mind that aluminum is a soft metal, and grit accumulation in the combustion chamber carves grooves into the piston. These grooves are an ideal place for the compressed fuel/air mixture to escape into the crankcase.
Why does the oil blow by when the engine is cold?
If they designed the piston for a snug fit when the engine is cold, the piston would seize inside the cylinder when it heats up due to thermal expansion. An under-sized piston leads to blow by when the engine is cold.
Why does my diesel engine blow by all the time?
As the engine heats up, the piston expands, and blow by disappears under normal operation. This is considered typical cold engine blow by, and it is unavoidable. As the diesel engine gets older, the cylinder walls wear out by constant piston and piston ring scraping. Over time, the cylinder bore becomes bigger by this constant scraping.
Can a cat engine still run after a blowby?

Purchase an engine flush formula from your local parts store and follow the directions. In general you will pour the formula into the oil and run the engine for a period of time. Once the engine has been flushed drain the oil and fill it with fresh engine oil. Replace the filter and see if the problem persists.
How can I get Oil out of my engine?
In some cases you may need to flush the engine multiple times to throughly clear all the oil passages and completely solve the problem. Each piston has an oil ring that allows the piston to travel up and down without oil passing the top of the piston and entering the combustion chamber.
