Got an idiotic problem.
There is oil comming out on engine tap, not in big quantity but it is noticeable.
Since I only recently bough th car I have no idea what couold be the problem.
There is also small quantity of oil coming in front of the engine near starter motor but I'm guessing this is only a gasket problem.
Have no idea why is it comming out on engine tap.
Car has around 110 000 miles on the clock (hd last five years checked in MOT office before I bough it and mileage seems true).
Front shocks are dead so there is lot of movement on bumps but cannot see this being the reason for oil on tap.
New shocks are ordered but still havent arrived.
Also outside temp sensor is acting like a drunk person and sometimes it works ok sometimes shows like I'm in Siberia (cannot see this being related to engine tap).
Oil was replaced some 500 km ago and is already quite black 
But the engine works like a charm (appart from lift pump which sometimes causes problems and will need to be replaced in near future or thoroughly cleaned again).
Does anyone have an idea what is the problem?
Is it possible the mechanic put too much oil in and is now getting out?
The tap itself is buggered?
I know there ere several topics related to engine flush or better said against it, but Is this tap leak related to too much gunk in the engine and if it is what could be the best action to take?

C'mon guys I cannot believe nobody has any suggestions?
Maybe I wasn't clear, it is yellow engine tap on the engine top

Do you mean the oil filler cap? You take this off to put oil in the engine yes?

[martin42]

you mean the oil filler cap
have you changed it for a new 1 as the seal could be perished,if it isnt tho you have some very high oil pressure issues
got beat to this post,must be getting old

[SIR Philbutt]

It is possible to put them on incorrectly and oil "spits out" (i've actually done it). Take off, check seal and make sure back on ok.

[mathewst]

I've tried removing it and putting it back on several times but it doesnt help
Yes it is oil filler cap sorry my mistake.

[bootie]

have you changed it for a new 1 as the seal could be perished,if it isnt tho you have some very high oil pressure issues

as Martin already said, get a new one and try that first.

[mathewst]

Thanks guys will try to source a new one first.

But I forgot still remains the question of engne flushing or quick oil changes due to oil getting black pretty quickly.
I'm guessing previous owner didn't know about 3000 miles interval

[bootie]

Diesels do get black pretty quickly anyway. Once you start doing regular oil chages you will see this for yourself.

Plenty of debate about flushing. It will be your choice in the end.

Some will say don't do it, some will say it's fine and just what you need.

My opinion is, if you don't know the history of the engine and it appears to run fine at the moment then just change the oil regularly, if you flush now you may well stir up a lot of old deposits which could block oil flow..... again, this is only my opinion.

Spent a better part of the afternoon going through topics on engine flush (got the time since being unemployed. fu... recesion).
I agree with you bootie and wont go with engine flush since I dont know the service history.
Will try some extra oil changes after the financial situation improves.
