My car has 30000 miles.
My car has an automatic transmission.

Hi there. The issue seems to have a misfire with the spark plugs and wires. The smoke that is coming out of the breather on the intake or valve covers is caused by the fuel burning on the exhaust stroke. I recommend replacing the spark plugs and spark plug wires and checking the timing on the plug wires from the distributor to the spark plugs.

If you need further assistance with your engine misfiring, then seek out a professional, such as one from Your Mechanic, to help you.
