yeah, but it could also be blocked rad :)

do a leak dye test would be best.

it's a blue fluid, and you but it in place of the rad cap, get the engine upto temp, if it stays blue all is well, if it goes green or yellow, it's the head gasket :)

Yes although the HG may not be leaking into the waterways when the car is at idle and may not show up on a dye tester.

I had this problem when I first got my GT almost 5 years ago and I tried everything before I done the HG, odds are if your thermostat is ok and your rad cap is ok, but after you give it some sustained boost like up a long hill you get water being spat out of the overflow on the expansion bottle then it will 99% be the HG.

90% likely the headgasket!

Like Turbodave, when i first got my GT years ago i had this problem, done everything first hoping it wasnt HG. Then of course it decided to finally let go properly.

90% certain its HG, if its HG, 90% certain its cylinder 3 pressurising the water system ;)

BTW, HG is yes 35-40 ish bu thats the HG alone from toyota. Full kit is a lot more. Its the valve stem seals that are SILLY money! i paid about £130-135 for a full kit from toyota, 165 i think with new headbolts. This was about 4 years ago mind.
