Just to make sure that i don’t get bored, i promised to help “JPS” with his Puch VZ engine. JPS is a very active member of the danish forum billig-scooter.dk.
The engine had knocking noises and leaked oil, so i’m going to change all bearings and seals. The crankshaft is also worn, so it will be changed to a new one.
There isn’t anything other wrong with the engine, all mechanical parts look good as new.
This gallery will contain all the images i take while doing the repair, remember to look for photo comments:
A short video of the noises, it was worse and visible in real life:
