Hey all, I had a spark plug blow out this week on my 2003 Silverado with 4.8L V8. Short of replacing the head, is an insert a legitimate repair that will last? I found this product at Auto Zone: http://www.autozone.com/autozone/ac...ir-system/_/N-26gb?itemIdentifier=141511_0_0_ Will that be sufficient? Also, I can't work on vehicles in the parking lot of my apartment. Would it be OK to drive it about 15 miles to a buddy's garage missing a plug? Any help is appreciated! Thanks!
