i guess a better way to check if he has bad seals is to do a compression test and a blow down test afterwards if compression is low

hope you find out what is going on shovelman

Compression test won't show bad valve seals. A leak down test won't either.

He as a couple of worn valve seals. Nothing more.

White smoke on start up. Water in the exhaust. Condensation.
White smoke when running. Water in the combustion somewhere.
Blue smoke when letting off of throttle. Valve seals.
Blue smoke when taking off. Most likely rings.
Black smoke. Fuel mixture issues.

Pretty much what I was thinking.

Problem is that it's quite the ordeal to get to the intake valve seals...

I wouldn't worry about it unless you are loosing more then normal amount of oil.

Yeah, might just experiment with different oils to minimize it.

At least you're not a crop-duster.
