Hello OK I'd say what most likley is the head gasket is leaking from its oil feed to the head and so travelling across to the water side either that or the head is cracked so whats worth trying before pulling the engine apart is a bottle of the block sealents that are available these days and can effect a reliable repair I can reccommned this onehttp://www.kseal.com/uk/?gclid=CPPhrayt4ckCFRW3Gwodm1MM7g

Hello well you said you had already replaced the oil cooler ? so i suggested the sealent as the next step
