Coolant came out of o2 dump?

Hey everyone, today I drove my car to work like a normal day and when I went to start it later to leave, it kinda hesitated, died then started up perfectly next try. I go and look under the hood and see a small out of Liquid on the ground where the dump vents to. Has almost a green tint to it. Idled really funky too after all this for like 10 minutes.
Kind of white smoked at idle too before I drove home as well. As I got home and checked everything out the dump stopped leaking and everything seems okay now? I don’t want to ignore this so any insight would be appreciated.

you sure your coolant lines on the turbo arent leaking? and the coolant is just running down the dump tube?

No leaks from the turbo coolant lines, I’m leaning toward the head gasket, found a milky white mixture on the oil cap this morning when I checked. Can anything else cause this?

That is pretty common if you're running e85. As long as the dipstick looks fine I wouldn't be too concerned with a little milky oil on the cap. Do you run a catch can?

Hey yeah I’m not on e85 I’m on pump, pulled plugs and they weren’t wet. Car has been sitting outside too for the past 5-6 months under a car port and I didn’t drive it too often. I’m going to drain the oil today and try to get a compression test done and coolant pressure test. Also, I noticed last week when I was driving it the a/f wouldn’t peg out normally like it usually does when off throttle,
leading me to think this could be fuel related. The stuff that came out of my dump could have well been fuel.


EDIT; also when I pulled the oil cap off I could kind of smell fuel. Don’t know if this correlates

Sure thing! Also the pcv was clogged pretty bad. I’m sure that has something to do with it.

Welp, changed the oil and took the car to work, after I started it up to leave again coolant spit out the same spot. Air fuel stayed at 11 the whole time while I limped it home, white smoked about half way too. Can’t believe this

Head gasket is blown. Don't drive it. Pull the head, resurface it, and get the valves done while you are at it.
With the head removed, clean the block face carefully with a scraper blade and brake cleaner to remove all traces of the old head gasket. Check the block face with a straight edge and 0.003" feeler gauge for any low spots. If you can get the feeler under the straight edge anywhere on the block face, pull the engine and get the block surface machined flat. Rebuild it, thrash it, break it and repeat!

Yeah i haven’t driven it since that day. I have a guy here in dfw that is going to replace it Jan 14th along with seals, head studs, intake manifold gasket and all the works. Stoked to drive it again but not excited to wait! I’m glad it never over heated though or left me stranded. But hey atleast now I know.
