steve1979 Posted October 15, 2010 Report Share Posted October 15, 2010 While the oil is drained, take the water pump off by unscrewing the three alan screw's ( you don't need to drain the system) and check the water pump seal if there's signs of antifreeze leaking out it needs a new seal. If it does there's a vid on you tube showing how to do this. Also if it needs a seal check the condition of the turbine shaft. May not be the cause but worth a check to rule it out Quote Link to comment Share on other sites More sharing options...

May not be the cause but worth a check to rule it out The milkshake is emulsified oil and water. they will not mix at a chemical level so the froth is what you are left with. There is likely to be a pump issue as already mentioned or possibly a leak from the water jacket gaskets on the barrel. Pump seems to be most likely at this stage from collective experience. If you strip the top end have a gasket set ready. Quote Link to comment Share on other sites More sharing options...

andytheplumber Posted October 16, 2010 Author Report Share Posted October 16, 2010 ok thanks, I will have a look but it looks like there has been some movement there because the pump cover is very new looking, Quote Link to comment Share on other sites More sharing options...
sting32 Posted October 19, 2010 Report Share Posted October 19, 2010 Very possible that if someone replaced the seal, to have put it in backwards. Devil's in the details. Quote Link to comment Share on other sites More sharing options...

If you strip the top end have a gasket set ready. Generally the frothing will be only related to the W/P seal failure. The base gasket on the cylinder does not have a water passage (only in an old 90's JT 250 model that had a water jacket in the cases). A cylinder head inner o-ring failure will allow exhaust gases into the coolant system and result in coolant loss out the radiator cap, mimicing overheating but can happen when the coolant is not at boiling temperature. An outer o-ring failure head will allow seepage at the head/cylinder junction. Jon Quote Link to comment Share on other sites More sharing options...
