Re: ISX engines Reply #25 – July 01, 2019, 05:37:52 pm I came across this article a little while ago concerning the ISX maintenance problems. The truck owner has quite a lot of experience and has some excellent tips for keeping your ISX running smoothly and at the least out of pocket expense but it will require you do some of the simple work. Not saying this is going to cure a bad batch of intake valves but worth a read. Pretty detailed but he summarizes at the end.The ISX model featured here may not be the one you have but I'm sure there are a lot of items that are the same.Cummins ISX CM871 Technical discussion | TruckersReport.com Trucking Forum |...Pierce Quote Selected 2 Likes

Re: ISX engines Reply #28 – July 01, 2019, 10:07:41 pm My ISX-650 was manufactured in 2008 . Done some reading and sorting thru the pile of stuff that comes with a new coach . Now I am perplexed about this engine. Is it going to blow apart on my way to the dunes or on the way home Maybe I am going to run out of luck . Didn't give it much thought before all this came up . but-, you never know ---Brad Metzger Quote Selected
Re: ISX engines Reply #29 – July 02, 2019, 12:00:39 am Brad, our engine was manufactured in 2010. You may have gotten one of the good ones. It seems like those that have gone down were manufactured that time and later. But there are no guarantees. Quote Selected 2 Likes
Re: ISX engines Reply #30 – July 02, 2019, 12:28:37 am I think that Brad works his engine harder. Like it was in a truck. Based on 35 years of driving used rv's I have rarely found one that was not babied The engine was designed for 80k weight and stick shift and hard use? Quote Selected 1 Likes
Re: ISX engines Reply #31 – July 02, 2019, 12:33:54 am Was looking at an 08 Country Coach with the ISX 650. So did a lot of internet research on the #6 valve problems. No way to validate it, but appears lightly loaded engines were more prone to damages that the ones loaded up. Appears that about 5% had problems. Thinking that you towing your big truck with the big toy on it, would put you in the loaded class. I would just keep the skinny pedal down and do a oil analysis every year and not worry too much.
