Hey all. I've just replaced the head on my 1.8 Zetec E, with a head thats just had the stem seals renewed and a headskim.
Now the car seems to be smoking a lot more than it was previously. Its hard to tell whether its oil or not but when I pulled the plugs they were all carboned up and the top of the piston was wet.

Could this be overfuelling?? Im running efi and I'm not sure of the pressure of the fuel pumps.
Any ideas as to where to check would be great.
