willem 0 Posted January 30, 2008 Author Report Share Posted January 30, 2008 Cheers, will check that out first. Is it likely to be a blown head gasket though? Link to post Share on other sites

willem 0 Posted January 31, 2008 Author Report Share Posted January 31, 2008 115,00 miles, actually the rad remains icecold even after half an hour. All tubes are hot. Boils over when revved. Engine keeps power though and doesn't sound off. Link to post Share on other sites
