well when ever i would go drive the 7 i would let it warm up and the water temp would heat up to normal tep but when i would get on the highway it would go back down to the bottom and the oil pressure would raise dramatically but when i would get off the highway the water temp would go back to noral tep, whats ever weirder is that oil would still stay high ( if i go above 4k rpm it would be in the red) and the turbos would not get over 5 lbs of boost, i changed out the thermostat a month before this all started. I am curently in the process of doing a complete rebuild on it, i did however notice that one of the apex seals had a few cups in it ( motor had 160k on it ) and the turbos are trashed so i have my work cut out for me haha. Anyone have any ideas on how this could have happened?
