Ok, I drained the rad fluid & tranny fluid, removed the cover. I see the O ring, but it doesn't seem damanged, I'll pick one up tomorrow to replace as well as new cover gasket. Another ??, Is the tube to move freely right now? I have some play there. By looking at the inside of the cover it looks like it would all pressure it together & keep from moving. Also, what adhesive are you guys using with the cover gasket. Thanks again.
