Hi All

Ok, so I started the 6 yesterday after around a week of non use, and noticied she smoked a little (white smoke) left it to idle and blipped the throttle and it fired out quite a cloud of white smoke, oh dear I thought fearing the worst! So I then thought right check for signs of headgasket failure. Oil looked fine, no loss of water, no pressure in water, heater worked fine. I then decided to do a compression test, results where great 180,180,180,180 on the dot. But after taking the spark plugs out they looked like this:





I then swapped them for a new set and the whole car felt better, also no smoke at all. Blipped the throttle and clean as a whistle. What I'm fearing is something is fouling the plugs somewhere and maybe its overfueling badly? The last plugs where not old so something is not right here.

Thanks

Andy

i would say your getting to much fuel into the cylinders, im no expert and ive not had this before but something is definatly scorching the ends of those plugs.....

It only gets used maybe once a week if that, just a weekend toy. Once I changed the plugs and gave it a good blast no smoke at all. The plugs are maybe a year old max, It's just odd they went that colour, could it be the lamba sensor thats broke? I have noticed its a new cat on the car - well within the last 8months.
