I just bought this minivan this week for shits and giggles but I still can’t figure out what’s up with the exhaust. I had it deep inspected by a mechanic, because I thought it was bad oil rings or something worse. He said he couldn’t find anything wrong. All I know is the 02 sensor are bad, and I added 1/2 of a Lucas oil stabilizer in. And the coolant reservoir hasnt gone down since I filled it a couple days ago. Note: this video was taken of startup in 100 degree weather after a 15 mile drive.

If your coolant is dropping then you have a blown head gasket.

Sorry that was a typo. The coolant level is still the same

What lead you to believe your O2 sensor was bad? I only say this because I rarely see them go but the codes pop up when other things are wrong.

Just error codes. Haven’t directly looked into them but the error codes pop up even after clearing.

Do you remember what the codes were and do you have access to a scanner that can read live data

I don’t remember the codes, I just got it scanned at autozone

Next time ask for a print out. IMO O’riley’s has a waaaaay better printed report with potential fixes and their mathematical likelihood of being the correct part.
