Engine Cooling problem
2000 Rover 45 4 cyl Front Wheel Drive Manual 169000 miles
I have found a small amount of creamy residue on the oil filler cap and a small sign of the creamy substance when I look inside. I also have very dirty/rusty/slightly oily water in the coolant resevior. I do not have any over-heating problems, or bad smells, no smoke, and no loss of coolant or oil. Why would the resevior be so dirty and why is there a slight creamy residue on filler cap? I have been advised to use K-Seal in case the head gasket is on its way out.
A slight amount of cream on the oil filler cap can be caused by condensation. But the other symptoms your describing do indeed point to headgasket beginning to fail

Even if I have no smoke or smells, no overheating, no loss of water or oil, and my heater still works. Would flushing the coolant, and adding a product such as K-Seal to repair gasket work?

Have a cylinder compression test carried out to check the headgasket for failure !! I have found that using a sealing agent very rarely works for long .. you could try flushing and adding ? ... I think ultimately the gasket will need replacing
