prob just condensation from been sat about, even if you wiped it ,
maybe a bit of condensation on the underside of the rocker cover, keep a keen eye on temps and oil etc and just see what comes about

I wouldn't worry about it to be honest.

Time it worry is when either the dipstick is covered in mayonaise or your rear view mirror is filled with smoke.

As a precaution just keep your eye on oil/coolant levels and coolant temperature.

Unlucky.  :(

Rocker covers leaking isn't uncommon though, sometime they leak past the 3 nuts if the washers have not been replaced.

Also, if the rocker cover is overtightened the sides can bow outwards, so it doesn't seal very well at all onto the cylinder head.

UPDATE

right the engine is going to be taking a different route now instead of me getting the head done straight away, im being patient and im currently negotiating a nice fully ported head with uprated springs from CGB Motorsport and to compliment this ill be adding a 285 cam and vernier iv also got my eyes on a front grill mounted intercooler which will then allow me to position the air filter in a much better place. now i know ill get slated for this over on the RTOC but im also toying with the idea of getting a tubular manifold and doing back to back tests and seeing just what is the diff if any would be interesting to know for sure.

All the above added to the 2.5" downpipe and GT Motorsport turbo elbow should get all the air/gass flow to its maximum which can only be a good thing ill prob stick the hybrid t25/t2 turbo i have on at the same time as well run at about 18psi

my new investment thought it was rude not too as id reckon my cylinder head wont be much good as its at least gone twice before plus this will go with the spec im going for

http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 3D1&_rdc=1

just watching and bidding on a t28 off a 200sx s14 now all ill have to do is change the rear housing to a .49 as the .64 will make it too much of a lag monster, with the .49 i believe ill be getting full 22psi boost at 4k

Interesting, the area around the base of the valve springs is clearly very different.

You will need adaptors for the compressor housing. See how the pipework is bolted on instead of using just jubilee clips.

They should be easy enough to find.
