I did a 4v conversion a bit ago and have driven the car maybe 20 miles. I pulled her out this weekend to clean her up and take her for a spin, found a dead battery so when it was out I noticed what you see in the last picture below. Certainly missing a line but wondering if it was just an overflow line or something. I did take it out just around the block and didn't notice any coolant on the car or even under it when I idled it, but I didn't want to drive it anymore than that and risk it. Any of you tech guys if you know what it is I super appreciate it. Also just throwing up a pic or two of her cleaned up. It has taken me 18 years since I bought it new off of the showroom floor to get it to this point lol. Did some Braum seats a bit ago and thought I'd post a pic of them as well for anyone maybe looking at seats. Obviously I don't have a lot of seat time but for the time I have been in the car they are really super comfy and look great.
