Oil consumption is a bit over a quart every 200 miles. Lots of blue smoke at times.
Yea, Iv'e never pulled a spring with compressed air holding up the valves.
Using the leak down tester to keep pressure in the cylinder is supposed to work. I'm going to find out.
The builder is more than willing to work with me on anything. He has ordered high end Manley seals for me. Thing is, for him to work on the motor, it needs to be out of the truck and brought to him. He was prepared to clear his schedule to start working on it, but I really didn't want to pull the motor if I didn't have to.
As I worked to find the issue, I was talking to him and sending him pictures.
The valve seals that are commonly used are a steel press fit on to the head, and a viton (rubber, whatever) seal against the valve. These manley valves have a rubber seal where they push on to the head, and at the valve also. He says they are just a better seal. He said he has only ever had issues with the seals he uses one other time.
The motor tilts to the back, and with the high volume oil pump there is quite a bit more oil in the heads at times. With the engine tilt, the back valve seals get flooded and the oil control isn't there at the seals. That's why #4 (The back one) looks so bad. Probably #8 (The other back plug) will look really bad also. Dimas expects that all valve seals are doing the same thing, we just can't see it on the plugs because they are not being flooded with oil. Recommendation is to do all seals.#4 and #8, but I have it all apart anyway. I was also getting a random misfire check engine code. This is obviously that issue also.
