Hello everyone I noiticed a few months ago that my mk4 cortina with the 1600 pushrod engine is collecting white gunk in the top cover, especially near the oil filler cap. The engine is fitthed with dellortos side drafts and thus the breather hose goes to an oil catch and i'm thinking it is the culprit. Im not sure but I have not seen any noticable loss of water fromthe radiator an i dont know what else it can be. any help ?
