Title: DIS Pack
Post by: cipher on 09 August 2006, 23:15:14
Some of the older members may remember a thread started by Ronnie in a place where we found our roots, about removing the breather box.

He stated that Vx should of put razor blades and barbed wire around it, for there being a chance of someone actually being able to remove it.

Well, after struggling for about 40 mins today, I managed to get two out of four bolts out (Thanks to LB for the tool loan  [smiley=tekst-toppie.gif])

Had to stop as typical british weather, it started to rain. Figured that installing a DIS pack in the rain wasnt such a hot idea.

Will keep you posted on how I do this in the morning.

But so far, it goes like this:

- Remove the wipers; There are two plastic caps (or there should be) covering the 13mm retaining bolts, pop these off, and then undo the bolts, they shouldn't be very tight. With the bolts out, then push down gently on the hinge in the wiper arm, and then whilst pushing down, lift the wipers from the shaft

- Remove the scuttle; Pull the scuttle rubber trim, then undo the T25 bolt holding the scuttle to the offside wing. Then undo the (I think there are) seven plastic clips under the lower windsheild rubber. These are Torx head, but they have a slot for a flat screwdriver in. Pull the peice covering the pollen filter first, then the main bit.

- Remove the plug leads from the DIS pack, and pull them up out of the way. I placed mine on top of the cam covers. Out of the way.

- Remove the wiring plug for the DIS pack.

- Depending on the year of your car (or engine) the DIS pack will either be mounted horizontally or vertically. Mine is horizontal.

- Undo the two bolts on the left hand side (viewed from front) of the DIS pack. access is tight, I found that I had to push the HBV out of the way slightly.

Thats as far as I got, so will update a bit more when I done tomorrow.

Hopefully, it will be easier to get the new one on.

.......  under the lower windsheild rubber........

Is that the same as a windscreen? Or do you have a hood & a trunk on the car too?  ;)

Yeah, I guess it would be the same.

It comes from watching too many shows like overhaulin and american hot-rod.

HAving worked a web developer for years now, I spell things Color, And Center, and Catalog that way, and still find it weird to spell them the other way, I just instinctivley type them that way.

Well,

The DIS pack is changed, and will complete the How2 later and post in the relevant section.

I dont think that there is any denying that the DIS pack was at fault for the misfire (although havn't tried it yet), take a look at the state of the old one....

Most people say that the HBV failing kills the DIS pack, well, in my case, I beleive that it was the rocker gaskets that did it. The Pack was soaked (and I mean soaked) in oil.

Yep.... that's  :-X ed!  ;D

I take it you have started the car and it ticks over ok?
Title: Re: DIS Pack
Post by: Marks DTM Calib on 10 August 2006, 13:14:16
The failure on that is due to the corrosion on the laminations, as a result of the corrosion the laminations have swelled and broke the casing.

Later DIS packs are fully sealed......for good reason.

Started her up idles ok (Thanks to mark is now under ecu control) and sounds much better to.
Still got to test drive it in a bit.
Can you change the plug so that a later type dis pack can fit an earlier car. Just out of curiosity.
Title: Re: DIS Pack
Post by: Marks DTM Calib on 10 August 2006, 13:24:42
Probably could.....
Title: Re: DIS Pack
Post by: nixoro on 10 August 2006, 13:44:29
Cipher what year car was that on, although mine idles ok it maybe worth checking it.

Do they all go like that the same and where would the broken pieces go maybe a silly question but I haven't looked at mine properly. :-[
Title: Re: DIS Pack
Post by: cipher on 10 August 2006, 14:11:15
The only way to look at them properly is to remove them.

Mine is a 96.

They tend to fail if they get wet (HBV Failure) or in my case, as it was soaked in oil from very perished rocker gaskets. I had oil dripping off the exhaust, it was burning it off, there was so much leaking it was dripping from the headsheilds.

Removal isnt difficult, just awkward. You have to put you hind into some very un-natural positions
Title: Re: DIS Pack
Post by: Kev on 10 August 2006, 14:13:23
Pretty much.

Here's how my mate Jims looked. Damged at the bottom corner.  :(

His symptoms were lack of acceleration. It didn't really sound like it was missing, but there you go.

Might have to take a look for curiosity purposes.

I might discover mine is in need of replacement only having looked through the history of mine i haven't seen any bills for Dis Pack replacement.

They usually go about 130K ish, but they can last longer.

like a lot of other manuf. they are wasted spark, less efficient that coil per plug (as per later Y series engines) but they are cheaper.
Title: Re: DIS Pack
Post by: cipher on 10 August 2006, 14:34:27
They normally crack, which is a sign that they are going/gone.

But the windings can fail.

It is a lot of work to remove it just "Out of Curiosity"

hmmm got me thinking now only mines just turned 136k, shall have a look at the weekend, can you actually tell by feeling the base obviously with the battery disconnected or is the base not accessible.

If removal is the best option I shall have a look.

Post by: cipher on 10 August 2006, 15:13:38
because the coils stand proud of the casing on the rear of the DIS pack, there is a recess in the mounting bracket to accomodate this.

So unfortunatley, you can't feel, however, depending how back the crack is, you may, depends where it has cracked.

TBH, I would just look for a replacement, keep this as a spare, and change it when it goes.
Title: Re: DIS Pack
Post by: Marks DTM Calib on 10 August 2006, 15:17:45
They can be obtained fairly cheaply if you keep your eyes peeled....how much was yours in the end cipher?

I think I may have a look at the weekend, like you say may be worth keeping a spare but to be honest I have been thinking to get this replaced for peace of mind.

It was 99p (Yes 99p) for the DIS pack, and £5.50 P&P so £6.49, Bargain me thinks; well, provided it works that is!

Very jammy cipher, just hope it works for you.

Is it a brand new unit or from another car.
Title: Re: DIS Pack
Post by: cipher on 10 August 2006, 15:49:41
It was used, but has no cracks, so hopefully......one of the pitfalls of eBay, you can never be sure.

I have a 2.0 so only 4 leads although you probably know that already ;D
Title: Re: DIS Pack
Post by: cipher on 10 August 2006, 19:14:03
if yours is a 2.0 then your DIS pack is much easier to take off, its exposed at teh back of the engine.....

Just behind the black plug cover (says Ecotec on it)

You could swing a cat in there!  ;D

There is bags of room inthe 2.0 engine bay, (and bags of room for improvement as well).

I think that you could probably stand between the block and the rad!

Seems strange that whenever I see a 2.0 now I always think Euugh! 2 thirds of an engine!.

I do a lot of mechanical work for my g/f's sister, there cars are amazingly simple in comparision.

They had a G Reg 1.0 Polo, an L Reg .995 Fiat Uno and now have an L Reg 1.4 (C14NZ) Astra F.

Amazingly simple. The polo had Breaker points in the Dizzy!

Engine looks the same as mine, when I come to do the Dis I will probably remove the bigger section of scuttle, like others have said it does look like you can swing a cat in there.

I cant say I have tried standing between the rad and engine but it does look possible with the engine tray removed.  ;D

Took her for a drive today across town.....

Good news is she seems okay. No misfire (Touch wood, obviously the dash is not good for this, I said wood, not printed plastic, still looks nice though), and is pulling like she once did.

But, has developed a few little niggles, that may have been overlooked due to the misfire.....

At that age I doubt the Polo even had servo brakes......its how VW got a name for relaibility, they had no features on them!

John,

DIS pack is working great. Shame I wont get feedback for it   ;D

Sorry, but as its fitted and working, I not parting with it. Bargain too!

Thanks again, and wish you the best in finding one.
Title: Re: DIS Pack
Post by: djx on 17 August 2006, 21:12:54
you may still get feedback yet, my account was hacked into so its been suspended. i have had to send them proof of name, address, etc. so hopefully it will be back running in a week or so.
Title: Re: DIS Pack
Post by: cipher on 17 August 2006, 21:22:21
Sorry mate,

Wasnt bitching, just all I got was the eBay say you are no longer registered when I tried to leave you positive.

Sorry to hear about the account, I had my PayPal account hijacked a few years ago.

Best of luck with it, and with the DIS Pack.

What year is yours? then I can start looking for you too.

There is often an early V6 in my local scrappies with a Cambelt failure
