That if you didn't need to replace the clamping ring life would be easier but I have a sneaking supicion that you have to pull that upper tube out to knock out the valve.
I can pick up the pan gasket ina day from Phil and I am definately more worried about my dealer parts guy getting the parts.

Personally I'm not too concerned aboput just blocking it off other than having to dump the oil seperator every few hundred miles or so. I was thinking tht if I can get a used drain tube at the wreckers then I will cut itoff and rig up a bottle to the end so I cna leave it conencted and then just dump the botle occasionally.

Anyway, I can wait to see what this part is made up like...
