Well I hope it stays that way.
I cleaned all my coolant system through a few days ago as I believe my head is going or is porous. I had small white bits of oil floating in the coolant, so I emptied it out, flushed it all through a few times, filled with water and a little washing up liquid and drove for a while.
When I got back, I re emptied, flushed and filled with new coolant and water, and since then I cant say that the oil has returned in the header tank.What I would like to know is, is it ok to do what I did with the washing up liquid, and if it does come back, how long shall I leave it before I get it fixed, seeing as it only shows a little oil in the water. Is there any other way that oil could get in there?
