Buick Turbo V6 Engine Build - Buick Power Part 3
Here's another interesting Buick tidbit: the factory Buick exhaust valve (on the right) has an oil scraper step on the valve stem. This cost-saving measure was adopted in lieu of a valve seal and sometimes caused problems with visible smoke on start-up. In fact, a common warranty solution was to pull the valves and install straight-stemmed replacements. The valve Merkel uses (on left) has no step and requires the factory valve guide to be cut down so a regular oil-control seal can be used. Note that retainer-to-guide interference becomes a problem when lift exceeds about .420-inch if the valve guide is unmodified. View Related Article
