I have a fault with the coolant level dropping low after 50 to 100 miles drive. it also looks like a trace of oil is in the coolant what do I have to do or replace to sort this problem out
if you can`t see a leak then it must be using water internally,oil in cooling system could be an oil cooler fault,I think if you have cyl.head problems then it would be easier to drop the whole engine g/box out as a unit
