I have a 2009 LMM with 127k miles, my oil pressure used to run at 60 when I was driving. I had an issue with my EGR cooler bypass hose and one day it drained my coolant dry on my way home from work. As I was getting ready to pull into the driveway, the oil pressure dropped to 0 and started white smoking out of the exhaust. I fixed the hose and added coolant to the fill line. Since then my truck runs anywhere from 45-55 on oil pressure. I checked my oil and I was about a quart low. I added Rotell t-4 10w 40. The oil pressure didn't change.
What could be causing it to not go as high? I haven't changed the oil yet.
Tldr;
Oil pressure not where it was at 60 before all coolant came out. Fixed and now oil pressure driving is 55. What's wrong?
Any help is appreciated, thanks!
