I also found milkshake oil in the TB, dipstick tube, top of oil cap, and the catch can was 3/4's full. Drained some oil out of the pan and it looked ok, no milk shake.




This is what I mean by milkshake, lol ^^^^

are you driving your car long enough to allow it to reach it's operating temperature? Say around 15-30 minutes? The milkshake stuff, from what I've been told is pretty in those areas because that's the coldest place the engine oil reaches causing condensation, and the formation of that gooey stuff.

I don't know what that is but it's NASTY! I had some orange-ish stuff in the radiator of my old Camaro but it all went away with a good flush.

usally when you are burning coolant whichever cyclinder is burning it appears to be really clean it is like steam cleaning the piston and valve area, that doesnt look like a coolant burning in that cyclinder but i am not a expert just have a lil knowledge on burning coolant

That is correct, if it were burning coolant, the piston would be clean. I wouldnt worry about the deposits on the piston, it looks like normal combustion.
I would look closely at the head gaskets, to see if one has been leaking water into the oil. You can usually notice a trail from the water hole to the oil return. I have seen this plenty of times on the LS1 engines.

to the top

Also someone told me you can tell by the oil pattern on the top of the piston whether an oil ring is bad or the valve guides are bad. Oil on the outside of the piston= bad ring, oil in the center, bad guide. Is this true?
