Sorry it took so long to post this, but here's what happened:
The 126 decided it didn't like the valve cover gasket anymore and rid itself of the apparent pest, resulting in oil everywhere, including my wife's car who was following behind me. Fixed the car at the gas station where it finally died, filled her with oil and drove home. Went to the car show to find out I pretty much missed everything.
This is the 3rd show this car has gotten out of because of the valve cover gasket mysteriously disappearing. It can't go 5 miles to a show but went over 50 miles (split fairly evenly between highway and city) the day before without issue.
I tell her every time I fire up the engine I'm not taking her to a car show.
