Unfortunately, the petrol circuit is not very well known to enthusiasts and it is not always well maintained.
Engine adjustment - video 02 adjusting the rocker arms In the first video of this series, we adjusted the valve clearance. In addition to the valve clearance, the position of the rocker arm relative to the valve stem, is also a very important setting. If a rocker arm is not positioned correctly, it can be adjusted, which is called shimming.
Engine diagnostics - video 02 BONUS defective rockers arm parts In video two of this series, we measured the rocker arm parts, and compared them to the wear limits listed by the VW workshop manual. In this video, we will show examples of rocker arm parts that are in less good condition than these of our AB 1300 engine from video two. This should help, to better diagnose the rocker arm parts.
