As posted in an earlier thread, I am the new owner of a 03' screw. Since I know very little about this vehicles track record and problems(if any), I was wondering about some rumors I have heard about my screw. 1st, is there any truth about the spark plug rumor in that some plugs have been known to crack the engine block? Also, what are other very important things that I should know, mechanical or non-mechanical about my screw? All of your help would be appreciated. I am just wanting to take care of my 4X4 the best I can. Thanks everyone. Paul

 

Max' use the "search" feature above and to the right and type "blown sparkplugs" there are too many threads to list here. It should give you an idea of what's happening out there.

By the way, welcome to the board, you will spend many hours here just reading the information.
