You block off the exhaust flow into the EGR cooler by installing a blockoff plate or steel freeze plug into the passenger side uppipe to cooler flange. Or you can completely remove the EGR cooler and fabricate a bypass to keep the coolant path through the oil cooler. Alot of guys do install the blockoff while doing head studs as it is easy to do it while you have it all torn down, but it can be done at any time.
what is the best way to get to the passenger side up pipe? is it easy accessible with the cab on? can i just unplug the egr motor that is behind the intake elbow? would that eliminate most of the gases or would that cause damage to something?
take the pass side wheel well out and you can get to the up pipe mpretty easy. yes you can unplugg the valve I think you want to do it when the truck is off. That will help alot but you should deffinitly get your up pipe welded to.
