Best way to destroy your vw engine is run lpg . We also have some big speed humps around us so I’d be a bit cautious how low it is
One of the saddest engines I saw had the valves receding into the head so far the rockers were hitting the valve spring retainer and making even more of a bag of spanners noise than a usual VW aircooled engine... no it was nothing to do with the fact it ran LPG according to the owner..
