Went to get the paper and came back blowing like a kettle! 6 mile round trip, couple of small hills. Radiator is a bit leaky, but holds a level about 1/2 "above the gills. The overflow pipe is a bit loose and that determines the level I think
Problem is I think, that recent activity has stirred uo 40 years of sludge despite flushing, back flushing etc. I have taken the side manifold off (easy with a new manifold with ss studs, as it's was the quickest way to get the*** bottom hose off. Sure enough loads of crud in the "gallery" that I flushed & scraped out. A small magnet on a telescopic handle picked up some solid flakes too. I used this through the lower rad inlet and got a lot out of there. However the salient point is that although the radiator was boiling merrily, the side outlet to radiator hos was only just warm. The radiator usually has felt warm all over in the past....cooler at the bottom of course.
Any thoughts??
