Did the valve cover gasket, and did the motor mounts and transmission mounts. As expected, they were badly worn, but what I didn't expect was that both of the lower mount bolts on the motor mounts were missing, so the engine was basically only held in by gravity. This explains why the motor mounts felt so badly. But, after the valve cover gasket and the mounts, I started the car up and it ran very poorly. Couldn't even get down the street without it dying on me. It was late, and I was tired so I just parked it and decided I'd check it out later.
Well, I got the latest shipment of parts from BMW, and figured I'd take a poke at it. Turned out that the intake boot had gone from being a little torn to almost completely split in two. Most likely from rocking the motor when putting the motor mounts in to make sure the engine was centered. Fortunately I'd ordered one in the BMA shipment, so I slapped it on, turned the car over and it tan like a top, even the cold idle runs pretty well. There are a few other hoses that I'll need to take care of , but the engine is running really well now. No odd noises (from the engine), no valve noise, just runs great (well, almost great, still needs a little tuning)
