Hi Shawn, I don't mean to disagree about your DIESEL vs Gas crankshaft advice... but "I think they are", as advice, without being sure, could lead someone with less knowledge to make an expensive mistake. In other makes of vehicles, the Diesel and Gas crankshafts ARE different for good reason. The forces a crankshaft experiences in a Diesel engine are often greater than those in a comparable Gas engine, so they often require heavy duty crankshafts and other components. I don't know how VW does this (if they even do) but it can be accomplished several ways, sometimes the Gas crank is Cast, and the Diesel is a Forged crank, which is much stronger. Or perhaps both the Gas and Diesel cranks are forged, BUT the Diesel crank has been Nitrited (sp), which is a special hardening process that strengthens the crank for heavy duty use, and Diesels usually constitute heavy duty use, due to their combustion cycle/characteristics. Anyhow, I'm NOT saying you are wrong, just that it's best to "be as sure as possible" before offering advice that could cost someone money. My apologies if I've offended you, as it's not my intension to, but as a retired mechanic I thought folks might like to know why there may be differences between the two crankshafts. So who does know for sure if they are the same? My curiosity has been piqued. Later Derek -
