It cooled off this week and I got fed up with the crap cabin heating so I spent today swearing in the rain as I drained the system, replaced all the hoses, flushed it several times because jesus christ it was pretty filthy and then reloaded it with 10L of new coolant.
The system must of really badly needed a flush because the heater core works a hell of a lot better now and both the upper and lower radiator hoses were about to fail. I also located a leak in the radiator. The bottom of the upper radiator hose port has a hairline crack that needs to be brazed shut.
Also I'm
STILL finding oil in the air cleaner. It's not the PCV. The contamination is staying isolated to the cavity between the filter and the carb inlet.
