Hi guys and girls, ive got a 94 wrx import not had it long the problem ive got is that every now and again it chucks water back out the overflow pipe from the bottle that sits inside the passenger wing. Ive searched on here and cant find anything ive even had weston performance check headgaskets and all is fine there, there is no oil in the water or vice versa. If you look into that bottle after a run you can see the water bubbling up like its boiling and if you rev the engine the water drops off then comes back up and although im losing the water if i check the header tank when cold the level is fine
if anyone knows what my problem is or has any ideas ill be happy to hear from you

try xspec is hinckley his name is graham hes a wizard lol

 

Sounds to me like you have air locked in the system

 

how do you get rid of the air though, ive ran the engine up with the cap off and heater on full untill no bubbles come out the header tank

 

 

specky ive got a subaru mechanic who works on subarus 4 a living whats ya number and ile get him to fone u hes based in brum

 

would imagine it to be one of the following:


bad rad cap (not sealing properly or opening too early)
check for leaks
stuck closed thermostat
gasket failure (only apparent on boost)
