We're still driving it but the cylinder head is cracked or something coolant is showing up in the oil (milky) I thought our radiator was leaking but no it's a bit more serious than that.
I have some fond memories in our little suzuki grand vitara we've gone some interesting places in her...
Hope it's just the head gasket as Don said. A new head won't be cheap, but still a lot cheaper than a whole engine. If it's just the gasket, shouldn't be too bad a repair. But, if it has overhead cam(s), well, the whole front's coming off the engine too to take the timing belts off. If it's a V6 or V8, better do both heads or you'll be right back at the mechanic's in no time. A lotta R&R on parts that only need to be removed once if you do both heads at one time on a V6 or V8.
