Chris cheapest option replace thermostat, while at it do what ron surgested and check all hoses for splits or tightness to make sure you dont have air entering the system, mine had a tiny tiny hole in the heater matrix pipe, then if all good and no luck,
Could be cracked liner, cracked head one of 2, warped block so not sealing great, or just something really really simple, the worst ive mentioned i havnt seen on a scoob myself or heard off so dont panic.it really could be silly, have you got a plastic header tank as these get hairlines crack,
