Oil Leak and Head intake runners cleaning ???

[gurucomputers]

I just pulled all three cam seals and the front main out. I am thinking that the major leak was from the rear cam seal cause the sensor was full of oil. I just need an educated opinion... By looking at the photo would you consider some of the leak from the rear valve cover. Also the other photos are of the intake runners on the heads. There is probably a 32nd to a 16th inch of sludge built up in there. I wiped the upper inch of one out with a rag. What it the best way to clean these out all the way down to the valve.

On my engines I first tried using a rubber gloved finger wrapped in a shop towel and soaked in Berryman's Chemtool B-12. This worked but was ******* the fingers of this old man. Then I came up with using a B-12 soaked rag wrapped around a long drill bill in a cordless drill. That cut the majority of the crud. I then cut q-tip swabbs in half and inserted the stick end into a short piece of brake line tubing, soaked the cotton end in B-12 and finished up. Worked great.

Wear safety glasses when using the drill and spread old towels arround on parts that you don't want to fling B-12 onto. (Aren't prepositions a terrible thing to end a sentence with? )
