Oil filler cap, Is this normal?

[ADMT]

Hi all, I have the issue where I keep having to top the coolant up, it’s very few and far between at this stage and the system releases pressure when I open the coolant reservoir. I’ve had this issue since I brought the van second hand a few months ago, I’ve had it service and recently had the cam belt and water pump changed. The van runs well…….but I’m paranoid about where the coolant water is going.

Looking at the oil filler cap, is this milky residue normal or does it point to an issue with the head gasket?

Any advise is welcome

I’d agree it’s normal, just keep your eye on the coolant level and it should find its own level somewhere lower than you think is normal.

When cold mine sits way below the seam in the header tank but it never goes below and I haven’t put a drop in over the last 30k miles.

My filler is the same if not worse than your picture.
