Wit's end with coolant at exhaust!!!
I was having an issue with coolant loss and white smoke from tailpipe. Was told it was likely intake leak vs headgaskets. Changed intake gaskets, fixed the issue for a day then it started just dumping coolant from every available place in the exhaust system. Was draining a full collant bottle in about 2 minutes. Was also checking for exhaust in the coolant with the tube and blue liquid which it stayed blue. Had previously done a degas pressure test and it passed. The only test I hadn't performed was compression test which all the cylinders output was lowest 160 to the highest about 185. Did not perform a wet compression test as I was mainly looking for base compression and consistency. Not sure what healthy is on these vehicles but considering they were all running pretty close I call it good. Also it idles just as smooth. Pulled intake a 2nd time and rechecked my previous work. Everything looked fine so I put it back together. Ran smoke free for about 50 miles now I'm back to smoke after it sits a bit but it clears up after a short drive. What am I missing? I will note that I had a small coolant leak from drivers side rear of engine that I noticed while it was parked in the shop. I'm assuming that would be the oil cooler? But oil is clean so it's not mixing. What other avenues on these engines can coolant make it into the exhaust? Drives perfect with no powerless. Thanks.

That could very well be it - I was wracking my brain trying to remember where coolant was used. I knew it was for something, but couldn't remember exactly what - I was thinking EGR, but it's not a diesel
