It can perfectly compensate minor wear, scratches and tiny uneven gaps on aging cylinder head and block surfaces, thoroughly solving engine oil leakage, coolant leakage and exhaust gas leakage issues, maintaining stable leak-free operation for hundreds of thousands of miles.

 

Complete full gasket replacement stabilizes engine compression ratio, eliminates power drop, unstable idling and excessive fuel consumption caused by poor sealing. It fully recovers original power output, combustion efficiency and working stability of DD13 heavy-duty diesel engines, extending the overall service life of long-distance transport trucks.
