dude99: The ALDA was wet inside with what looked like motor oil. After reviewing how it works I think the bad ALDA gasket allowed oil to be pushed in from the intake (think blow-by).
shertex: Check your PM
JamesDean: That's a good point! This is a tricky one to locate because the intake manifold hampers visibility.
I always appreciate all the ideas and feedback from the forum, thanks to everyone!
