im having a few problems with the coolant, it seems when i put my foot down at times, too give it a little rag the cooolate bottle top seems too pop off an starts sprayin water everywhere.

ive heard diffrent things such as maybe headgasket, or air lock in rad system. but my mates done a sniffer test too check heasd gasket an seemed ok, an water seems too be in rad fine.

any ideas on what else it could be

im confused what it could be

thanks

If you've already changed the rad cap, then that confirms the cooling system is building excessive pressure. Where does the temperature gauge read when this problem occurs?

temp gauge is staying as normal, i know its working for sure as the other day, my bottom rad hose came off an leaked all water an the temp gauge rocketd up.

yea changed the cam as my original one was leaking. yea its deffinitly building up pressure.

mine did this buddy. go for a good blast with lots of boost, then do the sniffer test again, mine only showed up after a good raz!

In 90% of the cases I have seen it is a warped block, only slight, but enough so water gets pushed out under high boost

take rad cap off, and see if any bubbles come popping up.

that after a good blast?, as after a good rag it seems too lose the water via the overflow bottle when the cap on that pops off.

headgasket kit from toyota, head skimmed, but i would get the block done at the same time cause the blocks do warp easily on starlets.

headbolts,

so around 200quid matey.

Theres not much more you can do, the only thing is give it a proper blast, then do the test on the expansion tank, or the rad cap. take the cap off str8 after u drove it, get a rag when undoing it HOTHOT!!

this was only way telling mine for sure.

unfortunately most chances are for H/G failure..
It is not neccecary for the car to overheat, maybe you were experienced head lift which drive to H/G failure
