Snake Oil!

I've used Seafoam several times on older engines but only on the top side to clean out carbon. Allways worked great.

Motorpirate are you sure the seafoam is what plugged up your oil pickup? Or could it may have allready been mostly plugged up and the Seafoam loosened enough gunk to finish plugging it. If the engine had that much sludge in it seafoam probably wasn't the answer to all the problems anyway. Just a thought.
