Working on my Kia Sephia

Yesterday I took my time, got a new valve head cover gasket, so I replaced that, and while I was at it I replaced my spark plugs. There were some american spark plugs in there, something one just does not put in a korean car. So I got some DENSO spark plugs:

Also, as I was removing the old spark plugs, my friend and I noticed that the spark plugs were in the engine VERY loose, which would have meant I would not have been getting such great compression. So after we got the new ones in, we went for a test ride. And WOW that made a difference. Ive got more power on the lower RPM's, it is guzzling down less fuel, and on the highway it is doing almost 500 RPM's less at the same speed. More MPG is better!

We also painted the Valve head cover, but we have to sand it down and redo it again some other time, as last night we did not have the time for it. It does not yet look as good as it could, so I am not going to be posting pictures yet.
