Checking coolant for dissolved CO is a sure test though.

Suggestion
Have you determined via a chemical test of the water that the head gasket has gone?

Mine is using water (not to much though) and there is a slight milkeyness in the oil filler tube, cannot see any leaking coolant on the garage floor.....
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi has anyone had to replace the headgasket on their 996 ?
If so is it a big job and how hard is it to do ???

Pressure test may or may not throw up a problem. Checking coolant for dissolved CO is a sure test though.
Slight coolant loss is much more likely to be a radiator begining to rot out. Mayo in the oil tube is "normal" for a 996 and nothing to worry about.
I'd put money on it just being the old mayo in the oil filler pipe scenario. I nearly passed out when I first saw mine - but later found out that it's just normal - especially during colder weather. As the engine gets hotter the hot air passes up into the oil filler pipe and mixes with tiny amounts of condensed water - thus forming the Dijon-like deposit. I reckon that you've just paid more attention to your water level than you normally would have and noticed that she's used a bit.
I must admit, I've been amazed by some of the horror stories that you get on these pages regarding engine (and other) problems with 996's but I don't think that I ever heard of someone with a cylinder head gasket gone (Yet[8|])
Hi, 99% sure its not your head gasket.
Use a combustion leak tester, to determine if you have exhaust gases in your cooling system.
If the test is positive then you will probably have a cracked cylinder liner.
Ps: pull the oil dip stick out and make sure there is no sign of coolant on it.
