Hey all, I have a 94 NA that sometime this winter started blowing white smoke at startup. It smokes for 5-10 seconds and then stops, seems to smoke worse the colder it is, or the longer that the car has sat. It did overheat last year when one of the hoses rotted, changed the hose and it seemed fine, it didn't start smoking until this winter. I thought that a head gasket would smoke all the time. I changed the oil and didn't see anything strange in it. What do you think it might be??
