In this video, we cover a critical step when tearing down an aluminum engine block: properly loosening the corrosion on the main cap bolts before you put a breaker bar or impact on them. Corrosion and galvanic bonding between steel bolts and aluminum threads can easily seize them solid. If you force a seized main bolt and snap it off deep inside an aluminum block, your block could end up as scrap metal. Extracting a broken hardened bolt from soft aluminum without ruining the threads or the main web is a nightmare you want to avoid. Watch how using a brass drift and a hammer to shock the bolt head breaks that corrosive bond and relieves tension, saving your threads—and saving your block!
