Wammers, feel free to elaborate then! If I don't have the right tools I'd still rather buy them than pay a garage to do a job that I'm perfectly capable of and will enjoy doing. If specialist tools cost a fortune I tend to adapt something or have something made up and if I do have to buy something specific and expensive it can always be sold on when the job is done.
If it's the same as the BMW timing kit it's a waste of money, you can set the cams with a straight edge and lock the crank with an 8mm drill bit. I've done a couple of M50 cylinder heads and an M52 head. I understand I need a small dti and adaptor too. Shouldn't be a problem, I have access to things like that at work and a machine shop that will make stuff in exchange for beer.

You can't lock the M51 crank with a 8 mm drill bit. Dimensions for locking pin are in my EAS "How to". Making one up is simple if you have a lathe. You will need a DTI and an adapter for the pump £20.00 or so off Ebay. And a Tool to disengage pump and hold the sprocket in place with pump removed. Make sure you get the correct one.
Yes the major diameter (block) is 12mm minor (pin) 8mm.
Wammers (or anyone in the know), can you confirm for me that this kit on eBay contains everything I need? Not including the dti and dti mount of course. Thanks.

A lot of that stuff is not needed on the M51 unless you want to work on other BMW engines. All you need to do pump timing is the timing pin, the pump remover/sprocket holder and the adaptor and DTI. Look for VW VE pump timing adaptor and a suitable DTI. Timing pin you can make. With this you can do pump timing cam timing and replace chains. BMW & LANDROVER & VAUXHALL 2.5 DIESEL M41 M51 TIMING & PUMP REMOVAL TOOL | eBay Can be got cheaper if you look around. Even has space for your adaptor and DTI that's where i keep mine.

Unless you are a trained gynecologist and can paper your hallway through the letter box i suggest you remove the inlet manifold. Makes life so much simpler.
