Well before I took the engine out I decided I better take the cam cover off for bank 1-3 to inspect.....glad I did.
Upon removal of the cam cover I immediately noticed a tremendous oil build up. It seems like this side of the engine was running a little hotter due to lack of lubrication. I am unsure if it has a clogged oil passage, or just the oil was so gummed up in the oil passages that it caused this side to run warmer. Anyway I checked the lifters for this side and sure enough two of them (one more than the other) could be collapsed almost by hand with a socket extension. I pumped them and dirt and oil came out that did not look healthy.
The cam cover for the 4-6 bank had maybe a slight discoloration. The underside was mostly a nice aluminum finish with maybe a slight golden hue- nothing I would call abnormal.
Now look at the cover for 1-3 and tell me what you think....
