Noises ?

Wildest speculations exist , when noises come out of the motor, which are not a daily. Even a rattle in the upper area of the motor occurs very often.

1.     The valve play must be adjusted. (light to medium noise, `tickern` )

2.      The camshaft bearing of the cylinder head has got abrasions.

3.     The camshaft is worn out.

4.     The camshaft drive chain is worn out or its tension is incorrect ( in consequence of a defective camshaft drive chain tensioner). ( medium noise of rattle and hammer )

5.     The rocker shafts have too much play.
