Help!!! Expansion tank is leaking and collant inside
is like Mud...Anyone had this problem before?
I suspect the expansion cover is loose and created some leak on the drain port but coolant seems mixed with oil.
HELP..

As s4master1 suggested...
Muddy looking coolant is indeed oil mixed in with the coolant. There is an oil cooler (oil filter mounts right on the oil cooler) which is the primary source of oil and water mixing in these cars.
Head gaskets can cause this issue, as well as more severe problems...but that's rarely the case in these cars. Get the oil cooler replaced, and see if that addresses the issue.

Err, coolant mixed with oil in the coolant side tends to be the oil 'cooler' failing..
it's that little silver box between teh filter and the block.. It's either that, or something like a blown head gasket, or cracked block..
