External Corrosion
I am getting some external corrosion around the water jacket cover and thermostat. I was talking tosomeone at the boat yard about it and he questioned me about changing the zincs. I was not aware of zincs on or in the motor. He showed me one that looked like a plug. Does the A4 have these?

not that I know of, although there may be somewhere you could insert one, I'd be a bit leery of that given you'll also have to change them.

The zinc recommended by the salesman at the baotyard, showed a zinc with a plug threaded on the end. He said it would go in the exhaust manifold drain plug. The corrosion I am seeing is almost like electrolisis,kinda greenish/blue. Its not bad, themotor is clean, and has paint. I am thinking I'll just clean it off and repaint????

you could always do both, plug in the zinc, wirebrush like a banshee and see what happens, eh?

Iam thinking that will be the best. The zinc can't hurt. Is it possible the motor isnot properly grounded?
