Sludge was the problem, I think the seafoam knocked some other stuff loose from the nooks and crannies. I dropped the pan and cleaned the sludge out of the pick up. Started up with GREAT pressure like 70-80 on a cold start that settled to 30psi idle when hot. Drove for the weekend and had to drop the pan and clean the pick up again. Looks like it may take a few oil changes to have it all cleared up.
When this first started to happen I removed the intake and valve covers to manually clean what i could, what i saw was like a scene from a horror movie. I wouldn't be surprised in the least bit if there's more crap hiding in there somewhere.
