Any evidence of corrosdion or brittleness on the wiring to the CP?

Any evidence of corrosdion or brittleness on the wiring to the CP?

None noticed .. but I wasn't looking TBH .. I'll check when I take out the other one ...

[05omegav6]

I only mention it, because I'm quite sure, having replaced both CPs and regularly changing the plugs, that my persistant intermittent misfire is loom related

Given the mileage on yours, the CPs are probably original, so perhaps due for replacement anyway. Can't speak for the plugs as mine are never in that long

[Entwood]

2/4/6 and plugs out .. 2/4/6 CP has some very tiny cracks , nowhere near as noticeable as the 1/3/5. For some reason the plugs look almost new compared to the other 3....

1/3/5 all have a small brown corrosion mark at the base of the ceramic part ... 2/4/6 are pristine ..



So, awaiting parts as they say 

and if anyone is breaking/binning a 3.2 in the near future .. I need a new cable tray cover ... this one has now seen better days ( is that how you describe one in 3 bits ??     )

[albitz]

Its fairly likely that a 3.2 Elite will be being dismantled sometime in the next few months.Who by and when exactly is still uncertain but it will probably happen.A bit vague I know,but cant be more specific at the moment.

fair do's ...   but if the cable try lid is going spare .. please keep me in mind whoever is involved ...

As a reminder, when you refit the CPs be careful to ensure the plug is well clear of the socket at the back of the head

They have a tendency to get trapped underneath, and when you bolt the packs down it breaks the outer casing on the plug if I impart one useful thing today, let this be it

Noted and thank you ... not a lot of room on the 2/4/6 side is there !!

In answer to your previous Q .. no sing of damage, brittleness, or anything to the cables to either CP ... on the small parts of the cables I can actually see !!!

That brown is a sign of things in the plug wells that probably shouldn't be there, or plugs that have been in a lot longer than 2/4/6 given the difference.. It could be a sign that oil or something similar has been in there:

Could be down to a plug on that bank that wasn't sealing well, allowing exhaust fumes by.

They were all quite tight, not overtight but needed a firm push to start undoing. Lets hope the new CP's solve the problem .. can't think what else it could be .... 

[Kevin Wood]

It certainly sounded ignition related, so agreed. Coil packs or plugs.

Mine has occasionally thrown a misfire code recently, and is on original coil packs.

[aaronjb]

The brown could have been as simple as a slightly less-well-sealed rubber seal on the coil packs letting the atmosphere in, I suppose; the general oil vapour (or maybe it's only mine that has that given the state of the rocker seals ) and dirt would soon cause the brown..

[Entwood]

.. ... in a moment of boredom I decided to actually take off the rubber seal around the 1/3/5 pack and have a look ... I was surprised to find this .. which I initially thought might explain a lot, until I realised that was all round the "1" end and the codes I got were 0300, 0303, and 0305  !!!







Never mind .... lets just wait until tomorrow

Looks like new coil packs wouldn't go amiss anyway
