If the substance you are talking about on the coolant is WHITE, then that is just dried on coolant and is normal. If you ate looking oil mixing into the coolant it will be a horrible browny / creamy mayonnaise mixture in your coolant reservoir. This could be a sign of a head gasket leak. If your oil dipstick is dropping a few notches that would mean it burning about 1 litre of oil which is alot. So just be aware.Yeah I think where I’m loosing oil is the coolant as the cap has some wierd substance in it, and I don’t think I’m burning any as I haven’t had any smoke or whichever? And I’m only loosing a couple notches every couple weeks, after heavy use tho
