Okay so what I have found up to now:
- Dieselboys, write up thread on DIY cam chain replacement is an amazing write up. I found myself using the thread rather than the haynes manual to remove engine and split block. Really good thread and really well documented, which is why I havnt bothered to go into more detail on mine :)
- BMW's exhaust studs are shocking. One stud has snapped off in the block which I will have to drill out, the other three all the studs came out rather than the nut release. I will be replacing with stainless steel.
- There was a lot of fine brass partcles in the sump! :(
- Its a long old job just to remove the engine. Anyone who attemts it, book a day off work rather than on a school night and working till 2am! ooops
