I finnished the engine a few years ago, but never liked the way it ran. I was getting a lot of excessive blow by on the valves, and wasnt sure if they were even closing all the way. I was so disgusted I decided to shelve the project and build another engine just to get my mind right. Well now it is time to re-visit the Corliss. Upon investigation, I believe that where I went wrong was to cut the notches in yhe valve too deep. Im getting ready to re-make the valves , and was wondering if anyone who has built this engine has pictures of their finnished valves, and any advice would also be welcomed.
