head gaskets or worse
I was replacing my water pump today and on the top ports the coolant was more brownish. The bottom ports on each side the coolant is a nice green colour.
Does this mean I need head gaskets or is it worse? Oil on dipstick looks fine.
When I replaced the coolant a couple of months ago I don`t remember seeing anything weird in it.
The coolant is also a brownish colour but I don`t really see oil in nor does it seem to be separating in the jug.
I was replacing the water pump because it was leaking from the weep hole
The engine is a 5.3 with at least 150 k miles on it. I replaced the red/orange coolant with the green one when I swapped the engine in my 1987 Brougham.
Here are two pictures of the ports and the oil on the dipstick.

I'll get the hex keys tomorrow for the plugs on the block. But I am not sure I would be able to remove the one besides the starter because I already tried and rounded it off.
I am hoping to be able to remove all the sludge so it won`t come back.
By the way mods, feel free to move this thread to the GEN III Internal forum.
Thanks
Coolant was a nice green colour so it did mix on that side at least. Good chance it mixed properly on the starter side.
