Aaaaand it's broken again...

For the ones who remember: I fixed my head gasket a while ago. With that, I let the valve seats be overhauled, the head was not only planned, but also reduced by 0,5 mm… And no, it seams, with all that pressure that stayed in the zylinders, the piston rings gave up… 😑 But hey! New project: oversized pistons! Should I upgrade the piston rods, too?
