What would you guys recommend?

The mobil one 15w-50 shows 1200 ppm phosphorous and 1300 ppm zinc. Also list the 15w-50 for flat tappet applications

should i be worried about it?

You are wasting your money for that Mobil one. 15W50?
Your engine will be better off with a quality high zinc Dino oil 10W-30.
Was your intake coolant leak to the inside or outside of the engine?
