I had replaced my oem oil cooler lines like 5-6 years ago for leaking. I used dorman ones well just the other day while pumping gas one line blew off on the block end and pumped all my oil out. Tow strapped it home one of the mounting holes for the hose is stripped can I just pull the end piece off and heil coil the holes ands put back on. If so is it just the large headed bolt that needs to come off?
