So I've got oil all down the side of my block, and I'm hoping it's just what the desert sun has done to my valve cover gasket. I'm gabbing a new one this weekend and I figure while I have the cover off I might as well attempt a valve lashing. I've read a bunch of articles, but I'm learning as I go, and honestly this is the deepest I will have ever gone into an engine. I'm hoping to do it while the engine is running. I looks like it would be much easier/quicker, but for my level it's also a little intimidating. Any pointers???
