Socks Posted July 4, 2011 Share Posted July 4, 2011 its ether a gunge build up in the water system...try a flush with a new thermostat (like £7 new)if it still does it, headgasket.. or at least the start of it... Quote Link to post Share on other sites
QUADLIGHT GT Posted July 4, 2011 Author Share Posted July 4, 2011 is it worth doin a compression test.. ? only does it on a proper motorway blast other wise the its totally fine not had a single prob with the car. Quote Link to post Share on other sites

ktl Posted July 5, 2011 Share Posted July 5, 2011 mine does this every now and again, if it was headgasket wouldnt there be milky oily shit on the oil cap?its not oil and water mixing its exhaust and water causing it to pressurise. thermo was changed 4/5 months ago Sniffer test it to find out 100%..... but you need to go for a blast around the block before doing it.

Spuddy Posted July 6, 2011 Share Posted July 6, 2011 Try a differerent radiator cap. Quote Link to post Share on other sites
lukEp Posted July 6, 2011 Share Posted July 6, 2011 Try a differerent radiator cap.X2 if it's excessive but that's what that bottle is there for, it will dump excess water into it when hot and as it cools it will suck it back in. Quote Link to post Share on other sites
