I know all about the 6.0L Powerstroke's issues: Starts in the oil cooler, coolant side getting clogged with broken down coolant, starving the EGR cooler causing it to burst and fail, leading to failure of the cooling system which leads to blown head gaskets. Would you guys stand to reason that 6.0 Powerstrokes that are still running are probably ok? They are certainly an intriguing engine, and it seems that bulletproofing a 6.0L for stock or a little bump in power will solve the 6.0L's problems. Would you guys be afraid of a bulletproofed 6.0L? Id love a 6.7, but cant do the payments. I guess the other question is this: Is a 6.0L Super Duty still a viable pickup truck? Id love a 7.3, but I cant find one thats reasonable with under 300,000 miles.
