These parts have rough surfaces and pinholes and abrasive particles on top. When they work under extreme temperature and pressure in a cylinder, they contaminate it with abrasive particles.  These could damage all the moving parts in the combustion chamber. First, it wears off the piston rings and reduces its ability to seal the cylinder sufficiently. This makes it unable to prevent oil from passing into the combustion chamber. Which ultimately increases the pressure in the crankcase and causes multiple other damages.

INAPPROPRIATE MATERIAL: If you are to rebuild your engine for a second life, you must ensure that every component meets the high-quality standard. HDP engine parts are manufactured with high precision and OE specification. All of our parts work together as a complete unit. They are manufactured to withstand the high demands of the diesel engine.
