How do hard carbon deposits cause engine blow-by?

Hard carbon deposits are a result of inefficient engine combustion. Over time, these deposits progressively accumulate throughout several parts of the engine, including cylinder walls, piston ring grooves, valves, fuel injectors, Diesel Particulate Filters, Exhaust Gas Recirculation valves, turbochargers, etc. Hard carbon virtually cements piston rings in their grooves, restricting their ability to seal effectively against the cylinder walls. Also, hard carbon builds up in the cylinder cross hatch grooves, giving the cylinders a highly polished surface. These 2 conditions alone reduce cylinder compression and oil control, resulting in engine blow-by. Introducing remedial maintenance measures to remove these deposits effectively will restore operating performance and efficiency, while reducing wear rates to give longer engine life.
