robthebob Posted September 17, 2017 Share Posted September 17, 2017 Hi, I have oil and water mixed up in engine due to a oil cooler fault. I now have all the circuit dirty with a dense black stuff as you can see in the pic. Ideas on how to clean the engine inside circuits? Thanks, Roberto Quote Link to comment Share on other sites More sharing options...

Do I have to refit all together and clean the system the way you suggest? Wouldn't be better to try and clean now? And which are the water channels and which the oil ones in the engine block?

L90-v8 Posted September 18, 2017 Share Posted September 18, 2017 you will need to run it with both methods but it wouldn't hurt using a steam cleaner or a hose pipe to remove as much as possible before refitting the components you should be able to tell water ways from oil ways as the water ways should be tarnished a brown an full of that horrible grey sludge an oil more black in colour Quote Link to comment Share on other sites More sharing options...
