The hydraulic gap compensators in the valve drive mechanism of the K4M engine are used to compensate for thermal expansion of the drive elements.

Adjustment of thermal gaps in the valve drive is required for engines K7J and K7M.
For the K4M engine, valve clearance adjustment is not required, this engine is equipped with hydraulic valve clearance compensators

Usually, the replacement of the gasket under the cylinder head cover is required if there are oil leaks from under the cover

We remove the steering column switches for replacement, as well as when removing the steering column and instrument panel.

We replace the sump gasket when oil leakage is detected, when the leak is not eliminated by tightening the sump bolts.
