Re: 166 V6 coil pack
Well it was the spark plug thank goodness not the coil. Plug was covered in whitish powder on outside which I assume is high tyemperature/high voltage crud build up. Most importantly the white insulator casing had 2 small fissure cracks about 3-4 mm length - presumably causing the plug to leak its kV, esp at low revs.
Buisness part of plug was very carbonised, some erosion and certainly didn't look like it had been replaced 2500 miles ago, more like the original 62500 miles the engine has done. The little screw on cap was completely different to the new NGK plugs I bought, despite original plugs being NGK too. I'm going to make enquiries at NGK to see if there was a date when this screw cap changed - proabably 1999 when engine built!
Now I remember why I don't trust garages/dealers to service my car - they can't do it and they don't do it and then they charge you a small fortune for it.
The crap dealer in question is Dixons of Leeds. Obviousley they won't be getting my custom again.
Plugs were 3 for price of 2 at Halfords which at £39.00 for a pack of 4 makes good value. OK I know you won't need the other 6 plugs fopr another 60000 miles, but may be you had a recent 60K service at Dixons or a similar garage and they actua;lly do need replacing?!
