Im feelin good as to how quiet it has been in here, ie no severe probs. been 6 years now! either everyone is busy and or just not havin any major probs. im hoping we have a real winner with this motor. remember all the hype to build the most solid diesel ever?? then navstar was fired by ford. They had allready built a crapload of these motors by then. I keep my stuff forever so thats what im hoping for. im just sayin.
