Head Gasket, Leaking Fuel Injector, What Could It Be

[WogsRus]

Ok so an update.

Replaced all the exhaust manifold studs and new gaskets, all on the turbo side, cat seals and so forth, exhaust is leak proof.

The car still does it DAM IT. This morning it sounded like it was going to stall. I think it is fuel related. I recon a leaking fuel injector, going to have to pull them out and get checked. MORE MONEY.

I don't think it is a head gasket, as the collant we took out was clean as, and the new one is fine.

There was no oil in the water.

The hunt continues.

ALSO found with the new coolant, the car is running cooler, and there is more white froth on top of the water, but it's froth, like soap suds, and it disapears quickly. It only appeares when the car is very hot. If i take the radiator cap off, you can see the froth arround the cap, but if you turn the engine off it disapeares quickly.

DOES radiator coolant froth a bit. My dad ensures me it's not a head gasket. I have had no coolant loos or anything. LOL. Paranoid again.

Forgot to add, the car hasn't used any watter or anything, the exhaust doesn't smell sweet or anything. The car doesn't buble when hot or cold or anything like that. This only happens when the car is hot, above 80 degC. if you open the radiator cap, you can see fine bubles going past in the water, but the bubles are not air, as the radiator overflow, does not buble and the system does not get pressurised with air or anything.

Is it possible that there is some air still somwhere in the system?

I KNOW i know, stop asking so many questions.

HELP PLEASE SOMONE ANWSER ME.
