Something else you may want to check is the oil return holes...Are the valve covers leaking oil ??.A possible sign of oil buildup....Take the valve covers off and see if the return holes in the head are plugged... If so, that allows the oil to fill up and leak past the valve seals... It's possible only the one side is clogged...Also, if you find a lot of crud under there, the oil hole to the timing chain could be clogged causing a worn out chain...If it's been a while since the covers have been removed I would replace the gaskets....If the bolt holes in the cover are streched down, peen them back ....... I wish you luck...

exhaust

A properly functioning manifold heat riser valve will block off one side of the exhaust manifold and force the exhaust thru a passage in the intake, when the engine is cold, in order to warm up the intake mixture. This helps the engine when it is cold by promoting fuel evaporation and preventing fuel puddling in the intake. When the engine warms up a little the heat riser valve opens, allowing exhaust to flow out both sides of your dual exhaust system.

When an engine is cold and in cold weather especially, the water vapor in the exhaust will condense and form the fog that you see coming out of the pipe. Just like you can see your own breath on a cold day. When the engine warms up the exhaust stream is hot enough that the water vapor does not condense in the exhaust stream until it is well past the end of the pipe and by that time the exhaust has also dispersed in the air so you won't see a fog.
