I have a coolant filter on mine and I currently have about 10k miles on it since the last change. I cut my initial filter apart and did not see much and the current one still has good flow through it ( I checked it on 11/01/09). The casting sand problem at International must be really hit or miss. At best I noticed a small amount of deposition in my degas bottle which incidentally is what prompted me to install it. Since installation I have not noticed any more in my degas bottle which tells me I never had a lot of sand in the first place.

I think you are on target J-87. I wish we knew which IH plant,shift,date of mfg(if block and eng decal date is diff),and other data in a spreadsheet format. It is appearant that some blocks were cleaned better(like yours)which accounts for why some trucks suffer ongoing trouble and others never have a problem. It realy galls me that IH and/or

has not addressed it already,because it would go a long way in letting owners know if they need to take remedial measures or not. I feel certain more EGR systems would remain unaltered so maybe the mfg should be forced by the gubment to look into it(ya,ya I know,fat chance)for the sake acomplishing reduction in what ever it is they are tryng to reduce. Anyway,your comments are relevant to meaningful discussion instead of bashing

and blindly throwing money at these trucks. Ok I am suscribed
