Replaced cambelt and new head. But car misfire

Asked by Adith Jan 29, 2018 at 06:09 AM about the 2006 Opel Corsa D

Question type: Maintenance & Repair

Hi guys. I replaced the cambelt and head after the
cambelt broke and damaged the valves. The car
starts but have a terible miss on it. Replaced the
coil pack spark plugs and plug wires but still the
same. What can be the probleme? The timming is
spot on, on all the marks.

Go back to the basics , Do a compression test on all cylinders You may have inadvertinly damaged an intake valve during installation or didn't follow the torque procedure correctly !! Did you use a tap or thread chaser ( Of the same diameter and thread pitch ) to clean out the threaded holes in the engine block . did you follow the correct torque sequence ?? I strongly suspect that your a novice at replacing cylinder heads Go to ( Fel Pro or Victor ) for the correct torque tightening procedure PS I hope I am wrong but if I am right your right back where you started Good Luck
