I had a hose dramatically burst a couple of weeks ago in the parking lot of circuit (jerk-it) city. It was the tiny hose that makes up part of the oil/water cooler off of the oil filter(92 B230FT). The hose was getting oil soaked from a valve cover leak that finally did the thing in. I was considering replacing the engine with a 94 B230FT, as this one has what I thought was piston slap (92 745TI w/ 108K bought it cheap from dealer who claimed rod knock but it goes away whne warm). Now that I finally got it all back together I think the slapping noise was actually 2 things, a crappy alt belt that is splapping and a hole in the exhaust manifold gasket (I could be wrong). The idle is pretty smooth (not perfect) but now I notice fresh coolant seeping through the headgasket. So my overheat blew the head gasket and maybe warped the head, it still drives like a champ.
