1930 Cabriolet blowing white smoke from exhaust
Good Morning. Started my father's Model A and let it run for a couple minutes and saw from the exhaust the white smoke that led me to believe a head gasket problem Turned it off and noticed some leaks of antifreeze coming from one of the middle bolts off the head.. Not much of a leak and started it up again and same exhaust discharge but not much of a leak from bolt. Do you guys or gals think I have a blown head gasket? Thank you. Tom

Retorque the cylinder head nuts to 55-60 ft.-lbs. before panicking.

Don’t panic for sure ! one of my SIL’s after buying used cars would say I think the head gasket is blown, I would ask why do you think that, is starting to run rough ? Retorque the head, with it warmed check and see if you have bubbles in the radiator, do a leak down test , the white smoke does it smell like antifreeze, pull the spark plugs and see if one or more piston tops are cleaner than the others

Thank you very much everyone. I'll start by retorqueing the nuts and go from there. I will update how it turns out.. Tom

Hello, run a compression check too may help to find leaking cylinder. At least on a Model A, changing head gasket is fairly straight forward, may want to check for flatness of head to block also .

Tom,
When you retorque your head stud nuts start the process with your torque wrench set to 35 lbs. Then go to 45 lbs. and finally to 55 lbs. Resist the urge to go higher. Doing it this way will give you a good idea as to the where the torque was on your head at the start of this. If you find they are all at 55 lbs. from the get go then the head gasket is most likely going to need to be replaced. If not then there is a chance that torqueing the head will solve your troubles.
