When repairing or forcing an engine, the issue of preserving or increasing the resource of individual components and parts, on which the load increases during forcing, is acute.
One of these most problematic engine parts is the valve guide sleeve.
Serial bushings for eight-valve VAZ engines are made of special cast iron, which, unfortunately, is not highly resistant to wear. Serial VAZ bushings sin with poor geometry, and on many motors for a run of 30-40 thousand km, the valve play due to wear exceeds all reasonable tolerances, and when the motor is running, a characteristic valve knock is heard.
And only on the 2112 engine (16 valves) brass bushings (LS65) are serially installed, having a longer service life than cast iron ones.
The advantages of brass bushings are as follows:
- The best heat sink from the valve stem and heat transfer to the aluminum body of the head,
- high wear resistance,
- excellent compatibility with steel and chrome valves,
- less demanding on the amount of oil falling on the valve rods.
K bushings are recommended to be used for general engine boosting, as a necessary element of increasing the resource
