i have a 64 f-100 with the 223 six. i have noticed a lot of hot steam comimg from the oil breather cap. i checked the engine oil and doesnt seem to be burning any oil. my dads 64 with the same engine, does have some steam, but not as much as my 64. i know its supposed to have steam come out, but my 64 has a little bit more than normal. My 64 sometimes stalls on the road, i definatley think its the gas tank, but am now also thinking maybe of a vapor lock, with this steam. is there a way to fix this?? please help!!!!!!!!!!!!

Travis; Does this so-called "Steam" come out in a steady stream as soon as you start it up or within a minute?? What color.

Sounds to me as if you have a PRE-PCV engine with a road tube set up and the road tube is blocked, letting the blowby gases blow out the cap. Blow by gases, depending on how much oil vapor is in them can be anywhere from clear to medium gray in color. Once you start getting a lot of gray then you need to start looking at a ring job in the near future. Make sure the road tube is clear.
