Tiny little leak on head bolt - 200 Tdi

Noticed that there is a tiny little bit of moisture round the front head bolt on my 200 Tdi - drives fine, doesn't overheat, and the leak is practically insignificant - it's not losing coolant (well, it obviously is losing a tiny amount, but not enough to have made the level in the tank budge even a little in two months).

Is this a symptom of worse to come or can I just forget about it?

Fanks!

its most likely a sign that gaskets past best ,it would be worth thinking about changing it soon,15 years is a long time for a gasket

It's been replaced about five or six years ago according to all the receipts. Thanks for that, will keep an eye out.

no point in waiting till it gets worse ,as you might not get warning

Looking at things again, I'm being a bit of a dumbass with my terminology. It's the front valve cover bolt that has these symptoms, not a head bolt. Same diagnosis?

does rocker box have may inside under cap ,breathe heavy with cap removed

Sorry chief, can't quite deceipher that one... can you dumb it down a bit?

is there a mayonnaise looking paste inside /under filler cap ,does it blow smoke/steam or pressure out when cap removed
