MERCEDES BENZ 300E CHECK ENGINE LIGHT PROBLEM

1991 Mercedes Benz 300e • 225,000 miles

What does it mean if the oil is NOT milky and the car runs great, no check engine light but there is gray sludge in the coolant reservoir on a 91 mercedes 300 E?

Sounds like sealer was added which is a problem as it causes more issues and cures nothing.

Have the system power flushed and start there.

Thank you very much for your reply. Im worried its a head gasket and am really mad at myself for not noticing it earlier. So thank you for your help.
