Help, my AC guy over tightened one of the pulley bolts and cracked my timing cover. when I removed the pulley then put it back on the post the pulley rides on pulled off. No I didn't over tighten it, it came off very easy it must have been cracked before i removed it. I think the guy put to long of a bolt in it and it would not tighten so he put the impact gun on it, unfortunately it's been a year or so since he worked on it I think he will tell me to jump in a lake if I complained. where can I get one, I checked eBay with no luck, there are Dorman products for the SOHC but not for the DOHC. I don't think it can be welded but if that is my last hope I can try that. does anyone know if that part is aluminum or just pot metal? if pot metal I don't think it can be welded.
