You have to understand that once in awhile someone purchases a " Lemon " ! Heck maybe the engine was built on a Monday and the technician had a hangover or a late Friday afternoon and he or she was late for a hot date. In any case I have been on this forum for about a year and a half and can count on one hand the number of incidents where the engine internals were an issue.
What's really nice is the support one receives from this forum and the available information at the touch of a keyboard. So roll the dice if you wish, after all " Life " is a gamble isn't it.
