best buy replacement radiator

It needed a rad last year and your only just thinking of replacing it and now your shocked that you found oil in the coolant?

Dump a litre of water in your oil and drive 100 miles. Unless the breathers are clocked you probably wont find any sludge in the filler cap.

Modern engines are much better at burning off the deposits and feeding it into the combustion chamber to burn them.

No, if you can read, it needed 150ml a month, so even if London ignored it for a year, if would have lost 1.8 litres, which is about the header tank on my car, so stop being a complete d*ck with the doom and gloom as in all your posts. I doubt he ignored it, as he posted what he topped up with. It's far more likely it's a mixture of the cr*p stirred up, and any chemicals in the new rad to stop it oxidising. I usually flush through with water, clean the header out, fill it up, do a run to heat the engine up, let it cool and then dump the water, then top up with anti freeze mix.
Just keep an eye an it, and it should be fine.

Thanks, I knew it was losing 150ml a month because that was what I was topping up to fill to expansion tank to the max line. Every week I checked levels and filled up if necessary. When the weather picked up and I had a saturday to kill I changed the rad.

the oil in the expansion tank is just a tiny bit on the surface. It's not even a layer, just fragmented "islands" of grease on top of the coolant. if it was a head gastket leak I would have much more accumulated oil by now and I would have seen oil in the bucket when I drained the radiator. It is almost certainly just protective grease from the new rad.
