I’ve never seen this subject addressed here so I thought I’d ask. Over on another Chevy forum someone posted that you should hit the lip edge with a socket with the rounded lip squared off or a special tool. To do otherwise may cause the plug to leak. Just curious how others have approached this job while engine is in truck. Not worried about the others, just the bottom of block. Thanks.
