Broken Header Bolts?
Before I put a wrench to the rest of them, any tips on hwo to get the penetrating oil back into the threads? Id like to avoid more broken bolts if I can. The motor is out so I have plenty of access to the bolts, and I have been spraying them with PB. Im going to give them all a few taps with a ball peen as well as some heat. Any other tips?
