Hi guys I noticed yesterday that I had a coolant leak from the top radiator hose. As far as I could see it was just a slightly loose hose, so i tightened the jubilee clip and opened the header tank to top up the coolant. All I could see in the header tank was white foam/froth!I left off the header tank cover after i had refilled and started the engine. I then blipped the throttle a few times and with each blip water came surging into header tank form two off thehoses.

Im assuming that my headgasket has started leaking causing pressure in the cooling system and basically vapourising the coolant. I also checked the oil but there was no trace of water in the oil. Temp gauge is working fine and the temp stays in between hot and cold as always. Just wondering (hoping) if anyone has any ideas what else could be wrong if it wasn't the head gasket!?

Cheers, Blair

To confirm if it's head gasket have a coolant hydrocarbons test done. Checks if any exhaust gasses have leaked into coolant system. Takes about half hour and a local small garage should have the kit, no need for a subaru specialist. Drive it like a pensioner on sunday until you know what it is.

Cheers for the reply mate I went round to my garage today and the guy is goin to do a gas test on it tomrrow then I will know for sure. Was just wanting to know if anything else could be causing this. Its looking more and more like the gasket, not good!

I've just put mine in the garage today for a gas test as I'm suspecting head gasket failure
I did'nt have white froth though and my water seems fine as does the oil, but tones of white smoke/steam (either or both ) pouring from exhaust and sounds awfull engines wobbling like mad aswell
Hopefully find out for sure the problem tomorrow
So I know what your going through and it SUCKS
Good luck.

must be the season for it. Mine is just back on the road after getting repaired because of head gasket failure

got it gas tested today and the guy said there was no co in my coolant so the head gasket is sound. Delighted I thought I was goin to be well out of pocket!

Good news
So what's the result then - just a coolant airlock ?

Wish I could say the same.
I had a compression test done and there was no presure in the back (passenger side) cylinder whatsover so could be anything
all I know is that its gonna cost a small fortune

sorry to hear that mate. I had a leak in one of the back coolant hoses and was losing coolant. The foam/froth in the header tank was due to the coolant being roasted as it circulates the turbo to cool it, so turns out there was nothin to worry bout
