Hello fellow brickboarders I need some help -

So here's the story:

I bring my '87 244 (160,000) in for a routine oil change at a local gas station (i'm in boston and it's too cold outside to do it myself). There's been a tapping that I know is a cracked flywheel which needs to be changed. Coincidentally, as I pick up my car to leave, it stalls -- chances are the flywheel broke (but who really knows). So I talk to the mechanic (who happens to own a 740), and tell him to replace the flywheel. Two days later, I go to pick up the car and it doesn't start. He tells me that because I waited so long to fix the flywheel the jarring loosened the crankshaft bolt and caused the timing belt to slip resulting in valve damage.
Not knowing (until too late that B230F is non-interference design) I authorized the installation of a replacement engine. He tells me it's a '92. So I pick up the car 1 week later and now the brakes are almost to the floor and the car barely stops. 5 days after getting her back, she idles rough, erratic and stalls after 10 seconds.........and I'm out $2400. He's already junked the original engine so that's less evidence to work with.

So here's what I think:

1) lied to about valve damage on a non-interference engine to get new engine put in.
2) Date stamp on engine below 4th exhaust port say 12/17/86 -- 1986 engine
3) Brake fluid resevoir is almost overfilled and fluid is near clear -- did he put water into my brake system?
4) poor workmanship on engine and flywheel installation?

I've already contacted the Consumer Affairs office and will contact the Attorney General and BBB next.


Anyone with any advice would greatly be appreciated!
