Ady has now stripped our 1953 Mercedes 220 engine to identify the running issues.
As you can see, we have discovered two major problems which will most certainly require repairing.
Firstly, the pistons have been picked up in the bore causing scoring and the lines that you see. Upon further investigation we discovered a 26 thou clearance which is dragging oil through the system. This clearance should be around 3 thou. In order to rectify this we will need to bore out to fit new pistons. If we are unable to source new pistons then we will have to bore out and fit new linings. The linings will then house standard pistons.
Further more, you can also see the cam lobes are severely pitted so a new cam shaft and followers will need to be sourced. Failing that we will need to send away the original to be re-profiled.
