I topped up my oil yesterday and noticed that the inside of the filler cap had a creamy coloured film on it

any suggestions :question

[Grumpy]

Unless you're getting other symptoms, such as overheating engine or unexplained
coolant loss, I wouldn't worry about it.

You often get condensation forming inside the cambox, and if you don't run the
engine hot and long enough to burn it off then you get a slight emulsifying effect
with the oil at the extremities.

have an oil leak from somewhere but im damned if i can find it

I would suggest that an oil and filter change be done,clean the filler cap and take it on a nice long run to get the new oil all through the system.then repeat at intervals of about 3,000/4,000milesesp if the car does lots of short runs.

Do you mean that your oil level is going down but you can't see any sign
of leakage?

Or that you can see oil around/ underneath engine but can't trace it?

[Markie]

this is normal on omegas - dont worry.

Condensation mixes with the oil on short runs to give impression of mayo - many people panice thinking Head failure etc it is not.

2 ways to fix it - take the omega on a long vigerous run - it will clear. And regulas oil changes particularly if you do short journeys.

I rest my case mlord.

mine does quite a few short journeys and usually has a bit of mayo on the filler if i top it up!

Take a spark plug out and have a good look at it make sure its not covered in oil

Would I be right in thinking cam cover gaskets

[Grumpy]

At least you're leaking it and not using it. It's a lot cheaper to fix a leak than
repair a worn engine and/ or valve guide seals.  

If it's smoking then sounds like it's dripping onto the exhaust which would
suggest cam cover seals. If it is this, then ensure you clean the breather system
prior to replacing the seals. If you don't eradicate the cause then the new seals
will just blow again.
Plenty of info and genned up folk on this forum that will talk you through it.

Clean up any  external oil to aid identifying the leakage point and then run the engine
again to spot the leak. Don't just look at where it's dripping off the engine, that may not
be where the leak is originating from.
Same as a leaky house roof, where you spot the leak entering your house is normally
yards away from it's entry point through the roof.

in spark plug wells, yes. Do them both and nly use genuine vx gaskets
