head re skim?

[CJ_Derv]

Does seem strange though how is the water pump?? i know a friend who had similar problem but not on a 306 and he got away with changing the water pump and it solved the problem as the coolant wasnt being pushed around efficiently

Also another thing to check is your heater matrix take pipes off and put a hose to one side and see how the flow if through as as per Ruans thread of 'DO NOT BYPASS HEATER MATRIX' i had several headgaskets when i didnt realise the heater matrix was blocked so bad it kept causing head problems

Worth a check
let us know what you find
