i had a m3 cam snap in my old m50. only came up with 2 possibilities, either a. the guy who changed it didn't use the holding tool, or b. he overtorqued that cap closest to the break point.

Must be nice to be able to work AND have time during said job to post on a message board. :D

Yes she does "race" too. Took her just 4 DE's to move up to the Advanced run group.

I work at a hotel - no guests, no work ;) It's a nice setup.

Tell her congrats - it's cool she's into it. Most girls aren't.

Usually a broken cam is caused by not using a holding tool to remove it and the uneven force of one cylenders valve springs pressing up at an angle with a couple of the caps removed will do it.

The engine was still put together when it broke - in fact, it was running in 5th gear at around 3500 rpm at 75 mph on the Mass pike ;)

Just a strange "weak point" you know? I'd have expected the valves to give first or something.
