P1313 head gasket?
I've been having the code p1313 come up and my 97 disco is not running right( seems to be misfiring of course) I have had the head gaskets and cats replaced as well as plus and waiting on 8 mm wires to come in. When I pulled all plugs they seemed on. I did notice my coolant level has gone down and of course I'm losing oil throught the oil cooler lines and possibly elsewhere. I have 143,000 miles on it and wondering how to check to see if it may be the head gasket has messed up again???

Coolant could be a leak somewhere else, and a pressure tester loaned by the parts store can show leaks. Pump up to 15 PSI and wait like 30 minutes. Coolant can escape while driving if coolant cap is weak. If no noise like water running in pipes under dash, and no white smoke, that would be good.

I've always had the gurgling under the dash by the glove box but never noticed coolant loss. I just had radiator rodded out less than a month ago as well. I actually had a shop check for exhaust gas in coolant and had none. I was fiddling under the car last night and noticed a drop of green coolant on the end of a oil pan bolt towards the transmission. How the heck did it get back there? I see no other physical coolant leaks but still suspicious about the coolant loss

The gurgling, if not exhaust gas, is air/steam. You can purge this by parking on a steep incline or right wheel on a curb or ramp. Open up the radiator bung fitting (if it is still plastic you will want to get a new metal one). Fill and run until air expelled, and cap off. Air pockets in the cooling system can't transfer heat as well as liquid.
Coolant can leak from the head gaskets, the valley pan gasket, various hoses, throttle body heater, front cover gasket, water pump gasket, etc. A coolant pressure tester lets you pump it up, and constant pressure is applied while you carefully search for the leak.
Head gaskets love to fail and leak out the rear, the gasket material is very thin in that area.

Fill coolant jug higher than normal to help with the leak, drive at modest pace, watch heat gauge like a Hawk, carry some bottled water in case you need to pull over and cool off and refill.
I only work half days, the first 12 or the second 12, my choice. Maybe some of my answers would be better if I did sleep.
