Burning coolant? So there must me some sort of breach at the head Gasket / cylinder head / cracked block? I also smell, what seems to be a lot of gas under the check oil cap. I'll have to bring it ASAP, only problem is every dealer is closed, at least service is closed.
The smoke really hung in the air, if you know what I mean, kind of like when i start my 2-stroke outboard up. It was really dense smoke.
