Man, it just scares the bejesus out of me. I'm relatively competitent with stuff, but..I'll put it this way. It would probably be easier for me to make $800 than to do this right. Once the manual get's here I'll really take a look. I'm going to talk with a few other shops and see. The fact that it's not that tough of a job (for someone who know's their way around an engine) makes me think I could get it a little cheaper. The scariest part is doing it alone!
