It can be straightened but the cost is quite a bit more than a new one. Personally I wouldn't trust one that had been straightened even if it was a cheap process. Bite the bullet and buy a new one. |

You mean the crank mentioned in this thread? viewtopic.php?f=3&t=5081 Glad you had it checked I bet. Yeah they can be straightened by a competent automotive machine shop that has some serious crankshaft experience. Is it worth it? Maybe Would I trust it? Probably not. It may run forever or it might take a dump as soon as you fire it off. I'd get a new crank and be done with it. Oh, now is a good time to upgrade the rods too............

If the crank will still turn freely when the case is bolted together tightly I doubt the crank is bent.I would take it to a good automotive machine shop and have them check it out in a set of v-blocks.i have seen MANY VW cranks be straightened and never give a bit of trouble.if it was a cast crank i would worry about it but VW cranks are actually made from some of the best material there is. |
