Make absolutley sure you connect the plug leads up correctly as the ones for the 2-4-6 do NOT connect 2-4-6 s you would expect......common mistake but the correct connections are written on the DIS pack.

Thanks Mark.

yep already aware of that. Why 2-6-4 on the disspac I wonder? 

Its to do with firing order, and the fact it uses a wasted spark principle.

The 1/2 moon is visible to the left end of your photo ... the cam cover is "flat" at the same point, so a large "1/2 moon" of rubber is a part of the gasket ..... it has a tendency to a life of its own and to move ... but when fitted correctly is a snug, smooth fit. Small amounts of black sealant on the "sharp" corners as per the guide.

Once you see the gasket/cover of it will all make some sort of sense ..

I take it you have read/printed off the guide

Aaaaaaha! Now it all makes sense!!!! I can see how that would go pear-shaped! Is the 1/2 moon gasket that ''slots'' in quite stiff or is it like playing pool with a length of rope? 

No need to print guide.... it will be open on my laptop nearby in case I get stuck

The 1/2 moon itself is quite firm, but where it attaches to the rest of the gasket is "floppy" which is why, IMHO it tends to move. it is "shaped" to sit on the metal, and once lined up does fit well.. it is just a matter of ensuring it IS seated well before tightening everything up .... hence the use of torch/mirror ... I'm told the "experts" can do it by feel.. just running a finger around the 1/2 moon once the cover is in position  ... obviously whoever calibrated my fingers failed to do the job correctly !!!

Excellent.... Airfix all over again 

Cheers mate, thats really helpful

Its simple, the setup works on the waisted spark principle e.g. it fires one cylinder close to top dead centre on the compression stroke and another one which is top dead centre on the exhaust stroke.

As we have six cylinders and the firing order is 1-2-3-4-5-6 we get

Compression	Exhaust
1	4
2	5
3	6
4	1
5	2
6	3

So if we now consider the coil pack we get

5-3-1
2-6-4

Simples.......but not obvious!

Thanks for the info Mark. gonna be honest I don't really get it  but I appreciate the attempt to educate a prat 

[Marks DTM Calib]

The basics are that the DIS pack contains three coils.....the ends of each coil are connected to a spark plug and hence each coil fires two spark plugs.

On a compressions stroke (e.g. where you want to light the fuel air max) you need 20,000 volts, on an exaust cycle (where your pumping the exhaust gases down the exhaust) you need about 2,000 volts. Hence its called a wasted spark (as the one on the exhaust cycle is doing nothing henc eits wasted).

And the above explains why certain cylinders are connected as they are.

By just saying that I now get it! I didn't realise that. Thanks mate

Diss pack needs to be earthed mate - usually earths thro fixing bolts!

I see... so that's why it's bolted down! So maybe my idea of strapping it to the cable tray won't work then?

All together now......ow no it doesn't

I was quoted that over the phone , then when i picked it up they charged me £46 so i grabbed it and made a sharp exit  If its a BOSCH rip his arm off ...cheapest i could get bosch was £110 . Check the old one first RALF might not need one at all

  cheers Steve. Yeah, i've convinced myself it's the leads anyway so could save myself some bucks
