Dont worry about it until you have to reinstall the timing belt. Installing can be tricky, make sure the arrows on the cam sprockets are at 12:00 and the notch on the crankshaft is at TDC simply line it all up, turn the motor over by hand twice and make sure it is still at 12:00. the distributor rotor should also point to the number one spark plug <img src="/forums/images/graemlins/smile.gif" alt="" />
