Hi,
Greetings from overseas Belgium (Europe). I recently purhcased this vehicle which comes from the Dutch army(Nekaf).
The problem I get is that at a certain rev , there is a noise such as "clack, clack, clack)? This disappears when I rev higher or lower.
This happens when I am driving or standing still.
This noise does not happen at idling
We have changed the coil, put new sparkplugs but problem continues
Anyone an idea what that could be ?

I also find that at idle the steering wheel is vibrating - is that normal?

thanks
Chris

It is best to troubleshoot engine noises with a stethoscope positioned to find the location on the engine the noise seems the loudest. Once you narrow down the are for us to focus on we can more easily offer possible solutions. Many sources exist for the clack noise like fuel pumps, crank end play, crank oil slingers, valves, tappets, wrist pins and etc.

If the engine idle is rough the roughness will get transmitted to the steering wheel.
