c20xe water problem

[corsa_valver]

ive got a valver corsa, and was jus doin mi daily oil and water checks yesterday, and when i took off the water cap, there was som capucino style froth on the inside of the bottle neck, what could it be, head gasket, porous head, the guy who i bought it iff said it had been rebuilt, and it looks like it has, from the outside anyway! and the mile counter was at 900 and he said thats what its dun since rebuild!

Probably head cracked ('porous' head mate)
Oil in water = head

Water in oil = gasket

Generally speaking.

It may be worth refreshing the water and seeing if it get contaminated agian. I'm guessing that this is the first time you have looked at the water. So I think it would be a good idea to double check.
