puked coolant but passed pressure test????

So a while back discovered my truck puked a very small amt of coolant like less then a couple table spoons it looked like. my temps are average 184 ECT and 190-191 EOT. so i did some research and got help from you guys and did a couple pressure test with a new updated cap....

I hooked the line onto the top line of the degas bottle and never got above 11-12 psi it looked like. It stayed around 6-7 til I hit throttle hard. when I ran WOT for few mins back and fourth. so I parked and bled pressure off and it didn't seem to build anymore for the 5-10 min ride home.

2 weeks later went from Fairfield ca to Licoln CA about 1 hr and 10 min and ran it pretty hard and then the next day my friend wanted to see my coolant filter and i puked quite a bit... and my coolant lvl seemed to rise half inch from when I last marked it. maybe around 70 degrees whole day.

any ideas?

is your coolant level at the revised mark (does it have the new sticker?)

If no sticker the new "full" in the Min mark embossed on the bottle.

Did you take the pressure gauge off? what was the pressure reading during the puke trip?

Coolant will expand. As well, the hoses will flex to affect the level to a lesser degree. If you had a bubble in your top hose, that would affect your level as the temp changes.

Besides a bad HG or ruptured EGR cooler, the puking might have been a flash boil at the EGR cooler. This can happen when you stop after running it hard. If there is enough pressure created, you will get some puking. As previously mentioned, the level in the degas needs to be on the new low side.

Seems like your thermostat is failing with the low ECT.

so when the puke first happened I put a mark about 3/4in below the ONE line on my degas bottle (I only have one???) and even with the puke it did a few days ago it looks like its not even below the line.

1. I was not running with the pressure test the 2nd time it puked.
2. I dont think I have a bad egr assuming so at least only about 1.5k on a BPD egr cooler. and about 2 yrs on oil cooler.
3. Im getting the guy who does most installations for MKM Customs (sinister diesel) to do a couple of test on Saturday hes very knowledgeable and very polite with all my questions.

I attached a pic of my current coolant level anyone think its to high or? I only have one mark on the bottle.

the level looks OK, maybe just a tad high.

Are you monitoring the engine? I had the same issue with mine when it was stock, but when I got my insight and started monitoring it I found out that I was having "flashboiling" moments where my alarm would start screaming and the ect was at 235* but only for 8-10 seconds and then all would go back to normal temps. The factory gauges in the dash would never move from the "normal" position when this would happen, I had a ruptured egr and blown headgaskets.

I could be mistaken, but usually the flash boil only happens after you are shut down or if you had really high EGT and slow moving coolant (clogged oil cooler or EGR cooler). I guess if you had an air pocket in the system that could contribute to it as well.

Thanks for the update. I guess the pressure test you initially did was off the mark.
