I've Got Codes and Coolant
Driving home from breakfast and I smell coolant then get the following codes.
P1300
P0303
P0305
P0307
P0130
THey are misfires and an o2 sensor warning from what i can find, but the Coolant is running off the top of the valve cover from what looks like the throttle body, which seems like the standard issue from my searches here.
Would that Gasket going bad lead to the codes?

I don't think the throttle body leak would cause many O2 codes unless the coolant was shorting out your sensor. Which is definitely possible if you are leaking from the HG or valve covers. The throttle body heater plate is a very easy fix and can be done in about an hour or less. Or you can bypass it.

I checked the oil for fluid and found none, but the throttle body plate is definitely crusty with dex looking crystal like I've seen others post. I'll start there, but am bypassing it until the kit shows from AB.
Edit: I meant no coolant in the oil, but I did see the coolant on the O2 sensor which may explain the codes. I guess I'm on a seek and destro mission for leaks in the AM

Coolant hose to TB could certainly blow out a lot of coolant in 10 miles. Keep in mind that it is a safety item to prevent icing up the throttle body and sticking with throttle on. If it should happen be prepared to shove in "N" and kill ignition. Here's the layout so you can look for all the leaks.

I have neither syptom, but again it just started and I brought her home immediately while watching the ultra gauge, which never went above the normal 204 stopped at a red light. I'll know more tomorrow after I bypass and watch for leaks. It needed the new TB kit, so I'm kicking myself in the **** for not doing already.

Actually I think the usual "coolant in oil check" isn't really applicable to Discovery's. I mean it is but is not a reliable test. I had a HG leak, no coolant in oil. Currently have a weeping HG that is shorting out my precat passenger side O2, no coolant and oil mix. Sounds like you've just got a TB leak but just letting you know.
