Distribution 306 GTI

Someone could tell me where the crankshaft of a 306 GTI is covered, wears a hole in the pulley but after heating everything, mounting the belt and turning the engine by hand touches a valve on the piston. And I have everything well draft or so it seems to me, I will take another draft mark for the crankshaft ???????

If you tell me the year, the displacement and if you can the chassis number I look for it in the data and send it to you, give me your email for the mess

Solved, the alternator's pulley was turned and I was not dump
