I Started Smoking

[paulsherman]

1968 MGB. Probably 500-1000 miles since rebuild. After driving for maybe 20 slow city miles or so. Running pretty well. Looked back and saw that I was smoking quite badly. No noticable running problem. Stopped for a few minutes at hardware store (more fasteners). Looked under hood, no apparent problem. Started car, no smoke, drove home, no smoke, no leaks. Started again in a few hours, drove to the store and home again. No smoke.
What's up??
Thank you,
Paul

Paul, welcome aboard.
Was it black smoke, or oil smoke? Black smoke could have just from doing the slow pace, and loading up a bit.

Oil Smoke

Paul, maybe a sticky PCV valve diaphragm. Pop the top off and clean the valve with some carb cleaner. Intermittents like this can be a bear to troubleshoot, especially long distance!

I was thinking about the diaphram last night when I should have been sleeping. When I bought this car 20+ years ago, that was all that was the wrong, but I rebuilt it anyway, then replaced the diaphram. Will check it later.
Thank you.
