Sorry for the late response, hope you're enjoying the new year as much as I am! Except for the going back to work part lol! The lash adjusters looked okay, unless there was something I could have missed upon inspection, but 300 miles since I "fixed" the truck and they are still going. Compression for all cylinders is 140-150 psi for all 8 cylinders. Keeping in mind that I had 0 compression on two cylinders (2 + 4) both dry and wet.

Thanks Dave for your response. I ended up replacing the two fallen intake rocker arms and my truck purrs like a kitten now! With a slight popping in the exhaust, which maybe dirty exhaust valve. Hopefully dirty and not damaged.

I just took off my intake manifold on my 1999 5.4 f150. Two of my intake ports were not black and oily as the rest, they were clean and rusty. Does that indicate that indeed I need to replace my head gaskets? Thanks in advance.
