I am getting some drips out of the dipstick tube. Is this too much blowby, lack of evacuation or is it just a bad seal on the tube itself?

Check the end of the draft tube, if it's not plugged somehow, work your way up. I believe there's some kind of filter/mesh something or other where the draft tube connects to the block. Might be gummed up. Check to see that the crankcase is indeed venting. Do a search on blowby and you should be able to find the correct procedure for determining what is acceptable. I had a similar problem, smoke from the draft tube, dipstick, and oil fill. Turned out I replaced a perfectly good head gasket because I was using Rotella T......

Well I did check and it was venting but I am not sure if it is properly.

It is quite common to get some blowby from the dipstick tube. If you have oil consumption along with the blowby, you might consider a blowby test, otherwise, it's just the poor job of sealing from the factory dipstick and tube.
The dipstick has been a source of embarrassment to the factory for years. > They have, in recent times, built a much better design. Unfortunately, it has yet to descend to the automotive group. The marine guys have it! :P

No oil consumtion over here, should I seal it better with an oring or something of that nature?

You can try, but the problem is usually that the dipstick can and does blow off the seat of the tube, letting oily gasses past it. They condense when they hit the cooler underhood air, making oil drops. Some have put a small bungee on the dipstick handle to keep it seated. That might help. An o-ring might help. You have nothing to lose. Give it a whirl!

I think I may try the o-ring , see how that works 8)
