Re: Valve seals
Well, have a couple more updates on the valve seal replacement job. Seems like the previous owner did the valves for the left head with positive seals on both intake and exhaust and the right head with the fel-pro black umbrella type. Also the right head has completely different looking machining on it, which looks a bit strange to me (photo attached). Finally when going to do the 7th, cylinder, I realized that the spring was broken (pic attached), so I just ordered a whole set and will redo them all.
Should I worry about the different machining on both heads? I wonder if the broken spring has something to do with the truck dying at every stop, or the vacuum gauge jumping around when testing.
