This often indicates poor sealing between the exhaust valve and the valve seat (Part 612630050002). When the seal fails, compression escapes, leading to incomplete combustion. Replacing the valve set is the recommended solution during a top-end overhaul.
For heavy-duty applications, we recommend checking valve clearance every 60,000 to 100,000 km. If you notice unusual tapping noises, inspect the valve tips and seats immediately for wear.
Our parts feature an OEM-standard tri-metal structure and high-chromium alloys. They are Trusted by repair shops & equipment fleets worldwide for maintaining engine vacuum and preventing exhaust gas leakage.
