When mine got messy, it looked like mayonnaise.

Headgaskets had gone.

To the OP: when was the last time you had tyhe collant changed? The stuff in it that makes it work, stops it corroding your engine, well that deteriorates.

HEAD GASKETS HAVENT GONE ,, IT WAS THE ORIGINAL FLUID BAR 1 ,, ON 22000 MLS , IF THE GASKETS HAD GONE WOULD HAVE SPOTTED ON RAMP AS JUST HAD HEADERS PLUGS FITTED + MAPPED ,, THEN THIS MORN WOULD OF SHOWED SIGHNS IN THE COOLANT ? HOWEVER IM NOT DISREGARDING YOUR THEORY JUST YET , IV CLEANED & STEAMED THE TANK SPOTLESS NOW , IT WAS A LITTLE OILY IN TEXTURE BUT MORE MOULD HARD BLACK,GREEN GOO WOULD BE THE WAY I DESCRIBE IT ,, WASNT NICE THO , EITHER WAY

dont know how you would tell if head gaskets wer away just by it bein on a ramp mate if theres oil in your expansion tank its gettin in there somehow ie past the head gasket just keep eye on your blowers if they stop blowin hot air and temp is up then youl know for sure hopefully its just the coolant breaking down as said
