Hey Guys! So I have a 1953 CJ3-A with the original engine and tranny. For several years when I would be going up a grade at low speeds I would get this intermittent scraping sound from the engine bay. Like once every 20-30 seconds, it only last about 2-3 seconds. Now, I'm getting this noise more often and when I'm on level ground. Do I need new motor mounts or is there somewhere else I need to check? When I'm just at idle I don't get this noise. Thoughts???
