Well, I replaced the Valve Cover gaskets at the last oil change, and will replace the lower (sump) oil pan gasket at the next one. I'll try just redoing the clamps first on the ps line. When you spoke of replacing the O-Rings on the Oil Sending Unit, is that something that must be done with the entire crankcase oil pan removed or just the sump? Or must you remove the crankcase pan to get the sump off

?
Thanks, Dave.
