The engine requires at least a medium overhaul, and the specific solution depends on the condition after disassembly. Incorrect piston ring installation Repair or replace the air compressor.
I've driven diesel trucks for over a decade and encountered several instances of excessive blow-by. The main causes were worn piston rings or cylinder wall damage, leading to excess exhaust gas leakage. I remember during the last inspection, we found the piston rings weren't sealing properly and the air filter was clogged. The issue was resolved by replacing the rings and filter element. Regular maintenance is crucial - using high-quality engine oil to reduce wear and timely cleaning of the intake system. Ignoring excessive blow-by can lead to increased fuel consumption and even premature engine failure. During long-haul transportation, I pay special attention to this - minor repairs and maintenance can significantly extend engine life.
As a new diesel car owner, I initially didn't understand what excessive exhaust gas meant, but later learned some money-saving tips. Common causes include aging piston rings or poor fuel quality, and exhaust valves may also malfunction. You can check if the air filter is clean and whether the engine oil needs changing. Regular maintenance can avoid major repairs, saving both money and ensuring safety. I've tried some DIY methods, like cleaning intake pipes, which cost very little. The key is not to delay too long, otherwise the engine may overheat and fuel consumption will skyrocket. Now I service my car every six months, saving a lot of trouble.
