Startup smoke

Has anyone had success with seemingly endless valve seal failure and clouds of startup smoke by machining heads were seals seat to provide a much better surface for the seal to actually do it's job and last longer.

Valve stem seals, not valve seats, no?

Re: Startup smoke

Vavle stem seals should last more than 5 years if done correctly, so you should not be 'endlessly' doing them.

I assumed there was only one way... would failure be due to improper materials or?

Installing the spring retainers and locks after the valve seals could screw them up.
