Integra Sucks anti-freeze.

My friend has a 1997 acura integra 1.8l that goes through about 2 gallons a month. Its very odd because I can't see any leaks anywhere, and the hoses seem to be tight. Are there any other things that could be causing this?
Feel free to ask questions if yopu need any more info.


Thanks in advance: G-man422

Anyone?

It's probably being burnt up. Is there a lot of white smoke coming from the exhaust pipe all the time (not just on start up)? Is the engine old and tired? Does the exhaust smell sweet? Is there a loss of compression?

So how can that be fixed?

head gasket.

Ok, thanks.
