I have heard of other Mod truck motors (4.6/5.4 & few 6.8) having problems blowing the sparkplugs out of the cylinder head but neever had any problems until a couple of weeks ago. My motor finally blew one out but the problem is...the truck now has 63,000mi on it and the dealer is being shifty about the repair. I'm pretty sure there was a TSB out on it but I can't find it anywhere. Can anybody help? Thanks in advance...
