Check

In case of excessive oil consumption or insufficient engine power, this may be caused by damages due to dust or normal wear.

1

Check intake manifold between the air filter and engine, for penetration of dust.

A strong dust contamination in the tubing elbows indicates false air intake that is bypassing the filter. In engines with oil bath air filter a fine dust coat is permissible.

2

Check pistons and sliding cylinder surfaces regarding wear (damage caused by dust).

Checking contact surfaces of piston skirts and cylinder burnishing, being able to identify if damage was caused by dust.

Indications for checking cylinder damage caused by penetration of dirt.
