At some point in the near future I will need to do mine. I have heard opposing arguments on this issue.

1- The steam seals are not the cause, but a result of the guides wearing internally due to valve actuation not along the centerline. The original seals may be hard an brittle, but the smoke will return over time after new seals installation.( not sure how long).

2- the steam seals were not of the correct rubber material, as a result they become brittle and hard, thus leaking and smoking.
