I want to check my pistons before I just buy new ones. There is no scoring, and the ring lands measure well within spec, but I cannot find information on where to measure the piston diameter. If it's like other Mahle pistons, I know you have to measure "X" distance from the skirt. Is that true for the stock 94mm Mahle pistons? If so, anyone know how far from the skirt?
Thanks! |

Frankly, the 1.7 motor is the VW 411 motor. (Ignoring the engine tin and exhaust, and assuming the vertical oil filler.) So it's not that surprising they use the same color codes.
