Oily deposit in radiator water

[Tapitha]

I checked my coolant level today and found that the water had a brown oily sludge in suspension. This has not happened before and I wonder where the oil has come from. Oil level on dipstick is OK and doesn't seem diluted by water. Any suggestions?
Thanks,
Mike

I wouldn't worry about it too much.. Just keep an eye on the level.

Is there any anti-freeze in the water?

[Tapitha]

There is anti-freeze in the water. Fairly strong as Tapitha lives outside. The Minor has been laid up over the winter and I did wonder if the anti-freeze chemicals had loosened sludge in the radiator.

It may be wise to flush the cooling system, heater and the radiator.

"Lives outside....over winter".... oh dear. Hopefully you have run the engine regularly to make sure it's well lubricated - and the clutch not seized...
