Valve Seals

[theintimidator3]

1986 GMC C 1500 Shortbox
305 w/ 200267 km
Is there any way of stopping the valve seals from leaking before I replace them? Does any of the lubricants actually work?

Sorry there is no easy fix.

With one little puff of smoke after sitting for a couple days...how long does my 305 have to live ? And what are some good habits to use so I can slow the death of my motor ?
