what is meant above by "Studs" and what additional water filter system do you recommend?

No worries, man. Studs are replacements for the stock head bolts that stretch, particularly when you tune them or tow with them. ARP's are the ones in my truck. I have a bypass coolant filter kit similar to the one on DieselSite's website. It will eliminate the casting sand that ends up clogging your oil cooler and rupturing it and your EGR cooler. It's a small amount of insurance.

i wonder if that's what failed on my truck and destroyed my engine

I just installed this coolant filter. I think it is one of the best 119.00 investments for you 6.0 I also recommend Coolant Filter Ball Valves for an extra 18.00 It will make changing the filter a cleaned job. And while you at it purchase a few extra filters so you have them on hand and save on shipping just to order filters. And No I do not work for or have anything to do with dieselsite.com but there product in great!!!

Yeah we do, we use schaeffers in our fuel. do they have a high idle feture on these trucks like the cummins do? Thanks for all of the other info guys!

Yes, it is automatic on the 6.0L's. After a few minutes of idling in park it will automatically kick into high idle. Some folks have gone and wired it up to one of their switches to manually switch it to high idle.

hmm, it really isnt much of a high idle, i notice maybe a 200rpm difference, from 800-1000rpm, the dealer here told us to cut a stick and wedge it between the seat and petal to hold it at 1500rpm while idling, then they said they would "try" to rig up a high idle on a toggle, this was the first one they have done, so not sure how it will work....

also what causes the egr cooler to crack?

in CA you have to have a dot exemption for high idle. we installed it due to the guy would get stuck in his basket from the boom and couldnt get down.

The high idle is enough to virtually eliminate "wet stacking" due to prolonged idling... There are several threads about how to set it up.

The egr cooler is a poorly designed liquid to air heat exchanger, which operates exactly like your radiator, except in reverse, since you are trying to cool off your exhaust gas using the coolant. Unfortunately, the tubes are too small that the coolant flows through and they can't take the excessive amounts of heat generated from tuners. Add to that, when the oil cooler gets clogged with casting sand, it limits the amount of coolant flowing through the EGR cooler. All of these reasons cause them to fail. These failures could be eliminated by increasing the size of the cooling tubes in the EGR cooler, which would increase the cooling surface area and allow it to cool the exhaust gasses properly.
