In 1964 had a brand new Ford 4000. It did that on hot days plowing. Seemed like it did it when I was plowing one field in particular that had a lot of clay and was working hard. Just had to set under a shade tree for a while. It was brand spanking new and did it. Not sure why. Sounded like the gas was boiling like you mentioned. I was only 13-14 years old and I know it scared me!
