Q: White smoke ticking not overheating

asked by on

Engine light, white smoke, ticking under hood, checked coolant pressure its not leaking, not overheating, oil not milky, white smoke doesnt smell like coolant. Assuming from that it isnt head gasket.

My car has 207000 miles.
My car has an automatic transmission.

If you have white smoke out of the exhaust and are not getting low on coolant then you may have a cylinder that is low on compression or not firing. Have the misfiring cylinder compression checked on that side of the motor to see if you have low compression from piston or valve train problem.
