...and the pre cat codes can be ignored. No real issue bar the eml on. My old car was borderline, thrash it and the light went out drive sedately and the light came on.
 Could easily be a fuel issue too. But under lying cause is tired worn out pre cats. They have a hard life. But the main cats are still doing trier job so emissions no worries.

But knowing you, that orange light will be very irritating. 

Dont let TB scratch those beautifully polished wings btw.

Thanks Chris - yes I'd already had a look at this guide - very helpfull too.

TB - if needed would you happen to have a spare coil pack to get me going if it goes that route ?.

Windscreen seal  hmmm hada bit of a rigorous jet wash yesterday afternoon ....hmmm

Cheers
Ian,

I have my old one I think.  Its failing, but not failed (or at least wasn't).  Funniliy enough, cyl 4 like yours. If yours (or mine) is really toast, you can borrow the one out of TBE over Xmas to keep you going (assuming you don't have cam cover gasket leak or water leak - dont want to ruin it ) until you can get one.

Thanks Gents - so it's looking like possible cam cover seals / plug / oil issue ?? Where does the scuttle seal fit into the equation Chris.
Yes it's 2.6 - I take it the coil packs are a single component for each bank -yes ?
So do I need to check the n/s bank first.

TB - thanks I might just take you up on that - I'll have a go at it first thing and have a look through the guides on here tonight.
Cheers
Ian.

Yes, thing is it's a case of dismantling the passenger side 3gang coil PAC under the cable tray, examine coil PAC and wells to see what you find. If it's a loose plug re tighten and re fit everything. If it's oil or water damage, then you need go get whatever parts etc. Then re fit. So if you have a spare car...

What's the service history on the plugs? Are they due a change anyway?
How many miles on the car? Coil pac start to fail from 80k ish iirc, TB will advise on that.

Wind screen to scuttle seal has come away from the windscreen on the last 4 3.2's I have seen. This means any rain runs down the windscreen and straight into the engine bay. Plug end of Coil pacs are directly underneath the seal and was the cause of 246 cp failure on my current car. Wells full of rust residue, and the coil pac seal had been damaged by the previous gorilla that changed the plugs letting water in. Full vx service history.

Thanks Chris,
Plugs have done 50k since last change. As far as I can tell (and no reason to doubt all the service history I have) - the Coil pacs are original at 140k.

Tks TB - just about to have a look at it now - you're welcome to watch  ..think it's roast for tea 
Cheers
Ian.

LOL, thats the 2nd roast dinner I've been invited to by OOFers today

Ok. Given the mileage. I would be fitting new plugs and coil pacs anyway. Have those ready when investigating if pos.

Cam cover seals will be rock hard by now, so may as well do them too before fitting new coil pacs. Check the scuttle with a hose first, see if it leaks water onto the engine. Grab hold of scuttle and see if it pulls away from the screen.

Good for another 140k then.

Part way through - the scuttle panel was a bit loose - a couple of the clips missing under the rubber trim that covers them up  .
Cam cover gaskets were done about 50k ago from looking back at the mountain of receipts I have.
Whats the fix for the scuttle if it's leaking - silicone ?

[TheBoy]

I'd be changing the plugs as a matter of course as well.  Though at 50k, its likely they may have come loose.

I thought the leak was the windscreen rubber to windscreen 

Remove scuttle, then see if rubber is loose. If so, push it back on to glass (it grips quite hard)

[feeutfo]

Oh ok. See what's in the plug wells then.

Couple of clips missing won't matter too much. Main thing is the seal is still firmly clipped to the bottom edge of windscreen. Although water can also get in via the join in the two scuttle halfs.

See what's in the wells next I guess.

[ianu]

Ok.
front plug well (nearest radiator) - lot of white/brown dust, middle - bit of oil (not swimming though) and damp. rear - damp and signs of rust around base of coil pack.
Will get a photo up asap.

[TheBoy]

P0304 is middle one - cyl 4

[feeutfo]

If there's oil anywhere in there, you have failed cam cover gaskets. Which will only get worse. So could well ruin and new coil PAC or plugs about to be fitted.

*might* be worth torquing down the cam cover bolts to 8nm to see if any are loose, but overwhelming odds are the gaskets are likely to leak further ruining any new parts. Really needs new gaskets IMO.

[ianu]

Understood Chris - just a question of juggling logistics now to make that happen and be able to get it to the garage that can do it for me.
 I suppose I can get it back together and coax it to the local garage - probabaly not a lot of point replacing with a temp spare good one either then ?

Photos' below.
The pack:




This is a bit odd ?


The famous #4


The one at the back (best I could get)


All in a row:

[feeutfo]

Yep, oil and water residue. cp's fubar, plus somebody has been in there before and fitted a dodgy boot by the looks.

New seels and o rings.
Now cp's
New plugs
Then make sure that scuttle doesn't leak...

If you get a chance have a look at the cp plug and wiring, see if anything a miss, just to be safe.
