Just applied the smell test. A few deep breaths near knocked me out, but no
sweet smell
 could I detect.
I also seem to remember thinking the color of the oil I changed out a month
ago was weird, with a milky tinge, but I chalked that up to the oil having
sat still  all winter.
Another sign of blown gasket I guess.
