Question for the EGR valve guru's
I have already cleaned my EGR valve twice and I know it will need to be cleaned again later. The first time the truck lost ALL power and the second time it was starting to lose power so I cleaned it before it got worse. I don't want to buy a new EGR valve since it will just clog up again later. I can't block off the EGR cooler and disable the EGR valve because I can't afford any downtime with the truck. I also don't want to unplug it because the truck only boosts up to 22psi instead of it's usual 29psi with the valve unplugged. I also don't want to weld it shut because I feel that would increase my chances of cracking the EGR cooler since all the hot exhaust would be stuck in there instead of "flowing" in and out of the engine again. I know the EGR valve gives problems when it gets stuck in the open position. I want to know if the valve is ever completely closed or if it is always partially open. I was thinking about welding it shut and drilling 2 or 3 1/8" holes in it so that it doesn't get stuck open anymore and to still allow some exhaust gases to "flow " through the engine. I feel this would be a good compromise in terms of power/EGR cooler reliability/not having to clean the valve anymore/ and no downtime for a EGR cooler blockoff.
