Help with engine issue

Hello,
I am a novice with car issues and need someone to help point me in the right direction. My Landrover free lander 2 has a few issues that might be related but not sure what the cause could be.

When I start my car I am getting white smoke on start up only and juddering, idling mostly noticeable prior to driving for a while then settles down and only slightly idles.

There is also oil making its way into the airflow pipe and leaking out where circled in the image below.



I opened the cap in the image below and noticed it had oil and also no filter if one should be there? just a rubber inside cap and spring.

So these are the questions I have as I don't want to take it to a garage and get ripped off with out checking out the smaller issues that could be a root cause.

1. Is this related to needing a oil change
2. An oil filter change
3. Could this be the cause of the juddering and white smoke

Any help you fantastic people can give me would be very much appreciated!!

Thanks
Sam

Hello & Welcome.
2 points.
1.That engine bay is far too clean.
2. All the answers and attention from Freelander 'sperts is in the Freelander section. Post this there for lots of help & attention.

Good Luck!

Thank you Dan, Wonder if I can move the post there without duplicating?

Yeah it is clean I had a leaking injector seal and after it was replaced (spent the winter with only heating on the seats due to diesel smell in the vents) I jet washed the engine..
