[W.A.F.U.]

We did a 3400 head job in a Montana last week. According to the customer, the dealer did it under warranty two years ago. My tech had a lot of trouble getting bolts loose even with his airgun. Whoever put it together either was very strong and didn't use a torque wrench or didn't care and put it together with an airgun.
Somehow I doubt this guy still works for the dealer.
