Try and get as much crap and oil out as possible before removing plugs or it will fall into the bore.

Do the cp's come with new boots Chris ?

Any idea why the front plug well is full of powdery brown dust ?

Sods law TB - no one said they were small diameter long reach thingummies  :-X I don't have a plug spanner that'll fit these  :-X :-X. Oh dear - looks like a trip to the tool shop  :y :y
If it is loose - I can't tell by touch alone but the well was full of dust and took some hoovering and blowing to get it all out.
As advised TB, took the other side off and the story continues..... just uploading photos now. Stay tuned.

Chris - where did you get the Bosh replacement cp's I think I'll be needing 2...

Cheers
Ian.

Hafruds are open 'til 4. Probably got some sale things going on :y

p.s. You should be able to tell if the plugs are loose as they'll rock slightly if you try and wiggle them with the end of a finger. They are either done up or not :'(

Plug certainly didn't feel loose trying to rock it.... hey ho.

Ok to the Drivers side.



Definitely water in the plug well - above the plug 'nut' shape bit that the spanner I don't have would fit onto. Water droplets around the cp for this plug too.

tricky to see here - but other plugs: Middle pretty dry to be honest nothing really to report. Front plug well - the timiest bit of oil round the base of the plug.


Either way looks like this pack is toast too although maybe just hanging in there.

Windscreen scuttle leak:



This was loose all the way along the bottom of the screen. I've cleaned and re-seated it so that it's pretty tight now.




Slightly worried that the drivers side by the wiper spindle is slightly split and won't fit as tight as the rest of it - you can see where the water has run through onto the pipes in this picture


By the way Chris - thanks for the excellent tip for lifting the cp's out using another bolt. It just so happens that these Saab 900 Exhaust manifold bolts happen to be an exact thread match too - what a breeze that was  :y



Finally - all cleaned up and back together while I work out the repair logistics. Started it up. no misfire  :-X
Codes are now reading same as before except the misfire reported has moved from #4 to #5 - even though it's not misfiring. I'll assume that it's not happy with the general condition of the cp's and can't now make it's mind up.

Every day a school day - thanks everyone for their help - at least I know exactly what I'm up against.

Cheers
Ian.

Yes cp's come with new boots complete.

Had similar powder in mine. Put it down to evaporated water residue.

If plugs loose you'll feel it when undoing them. There will also be black soot around the plug base.

Got mine from all parts in slough. Genuine bosch. 71 plus vat iirc. Tb may remember price.

Thanks Chris,
I notice there's one in Oxford and High Wycombe too so I've got a few choose from. I'll give them a call tomorrow.

You'll need to ask for that price Btw. It was given to better an on line quote.

Cheers Chris - I've just found an on line price of £75 so I've got something to barter with. Thanks for the tip though.

And every cloud - I see I've been promoted to an Intermediate member now - excellent  :y :y
