Ive recently had a new wrc head gasket fitted to my car by a good friend whos a ford tech, since rebuild its misfired all through the revs no3 cylinder seems to be the problem as plug soaks with fuel, if you drive the car the plug will foul and car will clear, but still not 100%
im unsure if thats just the turbo pushing the car along the road as its 430bhp

i have just noticed that the crank pulley is lined upto the V GROOVE and not the nodule next to it?? can this be my problem, iv tired plugs leads cap arm injectors comp test cold and warm, as the usual suspects but no joy??

pls any feedback would be great
