That's what I heard too that they are a pain! But I gotta get it done, the one you posted will be about the same idea for the 98 correct? I probably will get the valve cover gasket set to change the valve cover and spark plug tube seal just looking around on weather to order oem or something from oriley and autozone will do.

 

I use an absorbent rag on a long rod with a handle (gun cleaning stuff) to remove any oil whenever I need to change plugs if my seals ever leak, that procedure is a crazy amount of work if some oil in the plug holes is the only reason you have to pull a valve cover!
