Wow! No, not TMI! This is all good & useful information! Thank you everyone! Yes Bart, I am inquisitive, always have been and always will be! So thanks for taking the time to go into detail to explain the TDC markings and how the engine relates to them. To be honest, I never thought much about engines before now. I’m sure it’s a “girl thing”. We just turn the key and go! Lol We women rely on the men in our lives to rescue us when engines go bad. My dad, who passed away October 2020 from cancer, was the quintessential “fix it” guy. I could always count on him to fix anything for me - from cars to dishwashers - and he was happy to do it. He did this not only for me, but for our whole family. We all depended on dad. About 4 years ago my car broke down on I78 just south of Memphis, dad drove all the way from Oxford and back (3.5 hrs) to fix it. Through the years, I can recall at least 5 other times dad rescued me on the side of the road. Also, Steve and I own rental property and dad was always willing to repair things for us, free of charge (“you pay for the part, that’s all.”) Steve unfortunately doesn’t have the”fix it” gene, at least not to the extent my dad did. He used to say, “I don’t know what we’re going to do when your dad is no longer here.” Well now we are there and we PAY for someone to repair things for us. We don’t mind, but it only reinforces how much dad helped us out, a true gesture of love on his part. So that’s why this has been so exciting for me! To be so interested in this at this time of my life and to be learning so much from everyone on this forum, is truly invaluable. I only wish dad was here to share it with me! He died before we bought the ‘49. When my mom saw it for the first time she said my dad’s father, my grandfather, owned one just like it! She told me she and dad dated in it! How I’d love to have that truck! â¤ï¸
