Since the exhaust valves aren't under pressure, the exhaust seals often are a bit looser to allow adequate lubrication to the hot valve. Better seals aren't necessarily better for the exhaust valve. But if it was smoking, I'd say it was getting lubed plenty good. [img]tongue.gif[/img]
If you're going to build your own pressurizer, take a look at plug defowlers for your home made fitting. I know a guy who tried to knock the ceramic out of a plug to make a TDC tool. He was a amazed at how difficult it was. The defowlers are pretty cheap and most auto parts stores have them.
