Over the past several months, this truck has literally blown apart a single spark plug on 4 different occasions. The metal (threaded) end stays in the block and the ceramic end is left in the boot but is badly burned and separated from the threaded end. This has occured on (3) different cylinders. The truck has approximately 64K miles and has been fairly well maintained. The plugs are the correct type and model. Any ideas on what could be causing this?
Thanks,
Adam

Maybe the plugs itself are busted. You double checked them? Another thing is, maybe you haven't changed plugs for a long time, thats why it got busted
