Think I'm in a hard water area

Just changed the HBV after a prolonged leak, I thought it was kettles that suffered from limescale not Omegas.





Spot the difference.

At least I didn't have to change it myself. I got me an apprentice now.



Cheeky swine wants payin VX rates for changing it for me now.
Gotta be a forum member in the making 12 years old and better than a VX fitter already.

Has the car previously had an oil cooler failure?

Not that I'm aware of just me not knowing where the leak was for a while.

I think I would flush the cooling system judging by the amount of limescale in the pic

Just water?  :o - I'd get some anti-freeze in that quick, can't be doing the HG any good.

What effect does the mix have on the HG?

To be honest? No idea.

But i remember looking for project cars, and saw one that had a 'true HG fail' - laidback66 commented that i could be run on just water on the way back.

But for the HG to fail, the coolant system had to have been running on pure water for a long time. So i guess its not good. I assume the water freezing would't help....

On the HG itself - none. But the water is corrosive and will corrode alloy around the waterways in the head creating tiny cavities until the water meets an oil duct or just jumps the HG and goes straight into the cylinder. If you remove the head you will find the HG intact, but the mating surfaces on top of it will have a porous appearance. If not too bad, this can be fixed by skimming the head until level and then using a thicker HG (in order to not increase the compression ratio).
