I Almost Blew Up My V10! (Cal-Van Thread Repair Disaster Averted)

The ultimate Ford Modular engine nightmare: stripped spark plug threads. In this video, I take on a full thread repair on my 2-valve 6.8L V10 engine using the professional Cal-Van 38900 insert kit. But things didn't go quite as planned. On Cylinder #9, the factory aluminum head gave way, shearing threads down into the cylinder bore. To make matters worse, a stray washer slipped straight down onto the piston crown right behind it! Watch as I spend nearly three hours blind-fishing out the loose metal shards using nothing but a piece of bent baling wire and some heavy grease before completing the tap. Plus, wait until the end where we tackle Cylinder #4 and expose a cheap, oversized 11/16" AutoZone temporary insert trap that almost ruined the plug socket completely. If you own a 4.6L, 5.4L, or 6.8L Triton motor, this is a must-watch safety guide to saving your cylinder heads without pulling them off the block!
