replaced the HPOP and now my egt's are 2000 at idle

Appearantly I am having the same problem as alot of you with the HPOP pouring oil. My seal in the back of the HPOP started pouring oil, so I replaced it and truck ran fine for a week. When I drive down the road now it is fine, then it runs like its running out of fuel for 20 seconds and my EGT's go to 2000 and if I lay into the throttle its clears up and the EGT's go back to normal. It also does it at a stoplight, truck idles fine but again the EGT's rocket to 2000. My pyro is in the drives side exhaust manifold and the have a evolution and a attitude stacked. Those are the only mods. Any ideas??

Question

Could the pump be producing less pressure/different timing than the original? I'm not sure if this applies to diesels, but a leaner gas engine will run hotter than a rich one to a certian point, could this be? Also, could the low pressure oil pump or any of the valleyand passages be blocked? How does your water pump seem at idle? Is the fuel okay? Any exhaust restriction? Did everything get put back and hooked up perfectly?

A leaner diesel will just run cooler maybe it is an electrical short and it is messing with your gauges. Best bet is to remove all aftermarket tuners and chips and see if problem still arises. Also it takes a good 25-30 miles to bleed the air out of a HPOP
