Yeah that sucks, depending on your time frame though may be able to help out, have got a nice running 530I sitting here that I'm pulling the motor for for a project, that'll end up having to be purpose built anyway. Would be happy to trade motors if you wanna bring yours down and give me a hand to pull this one out complete, I'll take your one and rebuild it for what I want and you can grab this good runner, drop it in and go.
