I've not seen the car, he took it to a friend of his who wanted £550 to replace head gasket, car only worth about £600 tops so not worth it on those numbers...
The K series engine in all it's guises is prone to CHG failure . There is no permanent remedy although fitting the later MLS headgasket, steel locating dowels,replacing the thermostat with the current grey item and then repositioning the thermostat housing helps considerably.
Some also suggest new oil rail and bolts but these aren't obligatory.
Regarding the quote of £550 thats a reasonable price providing that No 1 piston hasn't melted as is common.
Just google K series and you'll see the horror stories that abound on these engines.
I speak as an owner of a K series engined Freelander. I wanted to replace the CHG prior to it occuring to ensure the car was up to the current spec of engine mods and was quoted the equivelent of £1900 sterling. Most garages either price it high to avoid doing the job or cover their asses by again pricing for returns.
I tried to PX mine but NO dealer will touch a car with these engines down here.
