Island Time 1,239 Posted May 9, 2018 Author Share Posted May 9, 2018 OK, I got a couple of hours today to have a further look. I drained the coolant, put a whole can of degreaser into it, refilled, ran it 10 mins, drained and flushed. The I used a holts coolant flush, ran that for 40 mins, flushed, refilled with coolant. Now I've just run the engine in gear at the wharf, 2000 rpm for 50 mins, and the coolant is clear!! So, it appears as if the issue was the head gasket, but there was sufficient oil remaining in the cooling galleries to make it appear as if the fault was still there after replacing it. The one final test is to go out and run the engine at full speed for maybe an hour, but I don't have the time for that right now.To say I'm relieved is certainly an understatement! 3 Quote Link to post Share on other sites

ballystick 73 Posted May 9, 2018 Share Posted May 9, 2018 I once replaced the head gaskets of an Alfasud Veloce Sprint, after running it for a while there was a massive fog bank gathering behind the vehicle on it's first road test as the coolant vapourised. I was in shock, however, I persevered as I thought my job was completed correctly so I took it for a half hour road test and finally the fog disappeared and the vehicle was returned to the owner. It had me worried for a while though and mainly through an experienced service manager backing me meant that I didn't disassemble it again. Quote Link to post Share on other sites

Island Time 1,239 Posted May 10, 2018 Author Share Posted May 10, 2018 Oil is supposed to be in the sump! I guess you mean water? Water in the oil is far more common than oil in the water... Quote Link to post Share on other sites
