IMHO,I think it might add sugniffent life to the cooler because it would have to disapate less heat with the reduced amount of coolant that the partialy plugged oil cooler allows. The results would undoubtly be closly related to the eot & ect differince at the time action is taken. On a related note,I believe these engines needed a coolant filter or a clean block from the beginning ,or as soon as you can install it regardless of what else is done. Any other comments?

The EPA have taken things this far and in my opinion the idea that the regulations will become less stringent is unlikely. That in my mind has as much probability as the return of leaded gas. I think we are stuck getting away with what we can(if anything at all) and places more emphasis on keeping the older engines running longer(aka 6.0, 7.3 etc).
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.
