Hello BB'ers,

Over the last 9 years, I've accumulated four 93's one of which is gone, but not departed. The BB and its notables have been extremely helpful in providing sane and sensible advise in car repair and maintenance, and I am grateful.

Today I thought I'd canvass the BB for an opinion on whether I should replace the head gasket on red sedan and green sedan. Red sedan with some 330k has been leaking from a spot above/near #3 exhaust for at least 80k miles over the last 3 or 4 years. The leakage rate is about 1 ounce every 75 miles so I keep an eye on the coolant jug and regularly refill the lost coolant. There is no question as to the location of the leak. Similarly, green sedan with 200K has begun to leak at the exact same location and leaks about 1 ounce every 50 miles. Neither car has ever overheated. Both cars are probably worth about $1500 (of course more to me). Oddly green wagon with 282K doesn't leak AFAIK.

At this juncture, I wonder if I should:

1) Replace the head gasket only. I ponder if I need to check the head for flatness as it has never overheated.
2) Use a liquid leak stopper in the cooling system. If so what kind. Keep in mind that these are old cars, so this approach might be the most sensible.
3) Do nothing.

What's your opinion.
