[QUOTE="Buzzgun, post: 2099238, member: 4715"] With 174K on the clock, I wouldn't worry about it. It really won't hurt anything. If you can't stand the smoke, the seals can be changed without pulling the heads, either by using compressed air to hold the valves closed, or by feeding a clean rope into the cylinder through the spark plug hole and then carefully rotating the engine to bring the piston up far enough to push the rope against the valves. I have been where you are, I have the tools and experience to replace the seals, I left them alone. [/QUOTE]
