This is untrue. My timing belt snapped, and when it did, the valve stem was hit and i had to replace the head or get a valve job done. replacing the head turned out to be cheaper. I would be curious to know what kinds of common probelms are had that a shop couldn't handle, because I am an ameuture and I replace the head and belt just fine, with a little bit of support from a friend.
Although for some reason it won't start at the moment. had a fault code of 12, starter switch.. then reset the ecu and no code, but still won't fire... everything seems to work I don't get it..
