I have just changed my oil stem valve seals in a hope it would stop my escort cossie replica with a fiesta turbo engine in from smoking... No luck.... Well ive only drove it 2 or 3 miles and its still smoking. Do you think I would need to drive it further to burn the excess oil off? Or like me do you think its still leaking oil??? I did a compression test and it was 150-160 on all cylinders is this correct? Checked the turbo pipes for excess oil and they seem ok>>> Any more ideas? I have a spare head im currently refurbin do you think it would be worth swoppin this completely? Once again thanks for any input....
