Leaks are never easy to trace. Your most valuable tool is your eyes and an inquisitive nature.

The level in my expansion tank used to vary regularly by a small amount. This stopped after I renewed the cap seals. Have you done that?

Some time ago I saw a 1.8 where the coolant pipe running from the thermostat housing hadn't been screwed back to the side of the block. The subsequent movement had caused a leak at the joint which eventually gave way. You could check that on your engine.

There's no easy diagnosis. It will take time and involve crawling around under the engine and taking a few things off. But one thing is certain; the answer is not to put gluey substances in the coolant and hope for the best.

Good luck with it Vinnie.
