how did you apply it, and where did you think the leak was ?

As mentioned in my previous post I've been driving the car for two weeks now and haven't seen a whiff of smoke. I will likely do the head gasket in summer, if I do I'll post some pics on this thread, I'm keen to see where the failure was and what the k-seal looks like inside the engine. Hopefully it won't create too much more work cleaning it all out... |

well the first mistake was putting it in the coolant bottle , there is no real circulation in there to carry the K seal around , I would advise take the top radiator hose off and pour it in there , that way it will stay there until the engine gets up to temperature then will rapidly circulate to all parts of the engine and system . The second mistake was not driving , the coolant flow is nowhere near fast enough when idling neither can it get hot enough ... a diesel generates very little heat when idling , a new thermostat is needed by the sound of it . from what you say above i would not be surprised if your problem was condensation in the exhaust , do you do plenty of short journeys? K seal consists of minute fibres of copper which are carried in suspension , and then settle in the crack , the other additive is a substance which hardens when it gets in contact with the air , so it solidifies around the copper fibres making a permanent repair . It is harmless and will fix any other leaks as time goes by , use a decent volvo coolant it is better quality and value than anything else .
