I have a stream of tiny little bubbles coming from the top pipe on my header tank on the saph cossie putting say an inch of pure white foam on top of the water with maybe a slight pressuring if anything, not really using any water, no mixing in the oil and no condensation out the back do you think it is head gasket failure ? the bubbles or foam go after about ten mins of it being switched off

If the turbo is very hot it could be the turbo retun feed which boils as the turbo heats it ?

The only thing ive done is top up the anti freeze, so would a strong antifreeze mix make it foamy at all ? or maybe ive used a watering can in the past that had screenwash or soap in it as the foam is only sitting on top of the water level not filling the header tank up and is pure white not your normal dirty brown gunk ?

The only way to say for certain it to check for combustion gasses (co2) in the cooling system using a combustion leak detector.

Paranoid???

Hope Im not getting the blame for this.

Stop worrying, if it's not using water, and performance is ok nothing is wrong.
The car may have had a flush used in the past, these can cause pure white effect as you describe and last for ages.
Depending on where any headgsket has blown, if it has blown outwards it would not show up on a sniffer test, as no gasses would be present in the coolant.

well i think i must of used the same watering can to mix some screen wash in and i must of left a bit in the bottom and then used it a while later to top the header tank up with

left bottle is water out my header tank and the right is fresh antifreeze with fresh water




this after they have both had a good shake, so i think i defo have some soap in the water system

Flush your coolant system with clean water a couple of time and all will be ok

BigErn

Agreed, give it a good flush and see how it is from there.

I've done that with screenwash in the header tank, came out of an umarked bottle that I though was diluted antifreeze I always write on them now
