OK.. this has been one helluva week with this.
After looking at it Monday, I could isolate the noise for the most part to the passenger side front of the engine. I took a "listening stick" (aka, a long thin piece of quarter-round.. basically a poor man's mechanic's stethiscope), and put it on the head just above the exhaust manifolds on both sides. LOUD noise at cylinder #1. Knew at that point it was internal and likely in the valvetrain area.
Took it to the Ford dealership and told the mechanic what I'd done/seen/heard. Just as I'm seeing on here more and more, it is likely a lifter on its way out. I don't think they needles have come out of it yet, but it's probably close.
So.... new short block, here I come. Should go in this week. I'll update on this thread since I'm sure that others will have the same issues..
