Has it had a squirt of coolant from hbv?

You sure DIS is knackered? Misfire not caused by oil in plug wells?

Dis was dry, hbv seems fine plus it would need a miracle to work its way round the rubber plug to the terminal.

Just checked the ht leads, as expected no6 is completely caput  

Seen a new dis going on ebay for £79.50 inc p&p. Is that good value?

DIS packs are expensive. Remember there are 3 different types, so make sure you get the right one...

Yep, they are £75-£95+VAT (depending on type) if you have Vx Trade Club card, so £79 off eBay is not bad - though not a huge bargain either... as TB said, make sure you get the right type.

I've only read this quick, but am I missing something?

If plug lead 6 is shagged as you mention (as mine was) then surely this is the cause of the missfire, not the DIS?

The plug lead is knackered where it contacts the dis pack. You should see it. Really bad corrosion on the lead contact and the dis pack terminal is pretty much obliterated.

I'd post a pic if i could work out how to

Have you got a pic showing the numbers on the DIS pack? I've got mine back in and although I thought I was careful they way I've got my leads connected doesn't match up to the way it's numbered in Haynes. Haynes has a drawing of one with the low voltage connector at the back (long edge) and mine is at the side (short edge). I'm hoping I can get a pic of mine where I can see the numbers if I take the scuttle off and then I can make sure the leads are correct before putting the plenum back on.

Thanks, I have seen that but even when saving the image and blowing it up I can't read the numbering.

According to the note I made when i did mine :-

                         p
[size=20]4 [/size]     [size=20]6[/size]      [size=20]2[/size]    l
                         u
[size=20]1 [/size]     [size=20]3[/size]     [size=20]5[/size]    g

Thanks Andy,
Is plug where the low voltage connector is? If that's the case since it's on the left when facing the engine the leads would go to

[size=20]5  3  1

2  6  4 [/size]

That would mean I have 4 and six swapped around so I probably have 3 and 1 swapped as well.

Haynes shows them as

[size=20]2   6   4
5   3   1[/size]

And I think I've gotten totally confused with Haynes and my notes even though I did one bank at a time. It's easy for me these days. I put new lifters and the cams back in last week. After timeing it up I tried turning the engine over and it jammed after about 60 degrees. Took the covers back off to check everything and the cams and shells were correct so I put a rod in each cylinder and moved the engine back and forth but I couldn't see any case where the cams were down while the piston was up. I decided to repeat that on each cylinder again because I must have missed something but then the engine turned over like a dream. Still don't know what was jamming it, cams correct, shells all correct and sprockets correct. I was gentle with it but the engine hadn't been turned over since July so I put it down to a bit of rust around a cylinder wall or a full hydraulic lifter.

Note: Early Models DIS has different mounting bracket, while Interim and Later Models have same mounting bracket but different multi-plug connector.

Yes.

Thanks again Mark. I think I've got the later model since my plug has three rubber sort of rings around it to keep the water out and the socket on the later version is the one that looks to have room for the seal rings to go in. My car is a January 1997 model though so that has surprised me.

Thanks for the 'Yes' Andy.

The DIS packs only ran up to 2000, when they were replaced by individual coil packs, so having a later model unit on a 1997 car should'nt be surprising...
