Model A oil blow by from oil filler tube cap
Howdy all! Had an oil blow by issue out of the oil filler tube cap of my 1928 open cab pick up. Saw some discussions on here and none of the solutions posited seemed to actually stop the issue, just redirected it to somewhere under the car. I found an inexpensive solution that actually keeps the oil in the tube. I bought a 64-72 Chevy flame arrestor online. If you invert the arrestor and place it in the tube, it catches all the blow by droplets and they drain back into the oil tube instead of coming out of the cap and onto your engine or water hose. The part is under $10 and works. See pic of fitment. Hope this solution helps you too…
