Take the other rebuilt engine, this one is jinxed!  Will it turn in either direction?  If you can turn it backwards, perhaps a valve broke off.  If it's impossible to turn either way, something broke inside the case, and you won't want that case.

Without bad luck, I would have no luck at all!

Yesterday the engine  back in my Carat. Today the engine was run and it was beautiful. Sounded so good. While idling to allow to warm up and begin the break-in, it stopped suddenly, never to start again. In fact, never even to be turned by hand with a wrench  - seized solid. The rebuilder is flabbergasyed. I'm flabbergasted. He said in all his years on rebuilding VW engines 'he never had  a Vanagon engine do that. Two aircooled ones but never a 2.1 L WBX. Anyhow,  come Monday, out it comes for a tear down again.  I've a choice: take one of his other rebuilts, or wait for this one. What would you do? There are six to chose from. Jim is an excellent mechanic, and I think this is a fluke!

And, anyone want to speculate on the cause of this one locking up?

John
