The OP already stated he pretty much confirmed the noise is coming from the top end. engine restorer is junk, and STP is not the way to go.(sorry DV). STP will cause more probs. In the old days,LOL I rebuilt plenty of motors with that crap in it and it's a nightmare. Try the Rislone or some MMO in the oil to replace a quart of oil. If it's just a sticky lifter either one might work, but, not magically as soon as you put either one in. Give it some time.
So what do you think about Lucas oil Zman? I used to have the same or similar on a 318 and cured it with a 1/2 a bottle. Just asking since I use it in a couple motors and dont want to get a nightmare when I tear them out...

I have used lucas (4qts synthetic, 1 QT lucas) since I bought my truck in 2008 (2001). It was well maintained, and when I did my plenum gasket and roller rockers, the alvetrain was squeaky clean. But I think that is more because the oil change intervals were spot on for the life of the truck.
