OK, I have been trying to still figure this one out. In an effoert to try to avoid having to redo the heads I though a good induction cleaning would be in store. I did the Seafoam induction cleaning as per what I have found here and how Disco Mike said to so it. I also put some in the fuel along with a new fuel filter. I also put in new O2 sensors. It ran like crap afterwards and then sent searching other places for issues. Mike said to do a compression test and so I did. When I took out the fairly new plugs I noticed three that had a ton of carbon build up on them.

COmpression came out between 160-165 per cylinder. I replaced all the plugs and wires. I had a bad connection at the cap from the coil that I fixed with a new cap rotorand lead wire. Started it up and it ran much better, thought I was in the clear, still had valve noise but it calmed down a little. Took it on the freeway to check it all is OK and then it got even worse.

It feels as though it is only running on 4 cylinders. I can smell a bunch of fuel in the exhaust and there is no power when it comes to climbing a hill or even getting on the freeway. I figure I better take off the oil pan and check the pick up tube of the oil pump, eventhough I have had an oil pressure check that turned out to be normal.

I am now thinking that my heads are FUBAR'd so much that oil is not getting up there and I have frozen valves thus causing the massive headache the truck is becoming. If anyone thinks I am off base here let me know I am about to run this into a wall.
