Thank you Kornkurt for your rapid reply and the good news that I can use the dipstick in either engine! Since the oil pan was off the 8 I was able to see the dipstick Full Mark lining up approximately with the top of the oil cleaner rim. Later with the oil pan back on I added 5 quarts of oil and noticed the dipstick was at the full Mark like it should be. Thanks again for this valuable Flathead Forum
I have a 1937 six cylinder and a 1949 Straight eight but only one dipstick and I do not remember which engine it came from.. Could it be the same for either engine? This is my first attempt to try using this forum hopefully I have submitted my information properly. I do not have either car just the engines with transmissions which are in running condition thanks!
