Help me identify these on my B5254T engine, 850AWD 1997

Hello everyone, please help me find the reason for the oil drops ( not a leak but anoying drops) - I took a picture and I need someon who can tell me the name of the parts 1, 2 and 3 and if they can be the reason for the oil drops?

Another problem - please, look at this picture and tell me if the direction of the airflow is correct as I am not sure it the valves (The round white objects attached to the vacuum lines) are attached as they are supossed to do so?

Thank you in advance,

Ivo

In the bottom pic, 1 and 2 are check valves, 1 goes over and connects at the exhaust manifold, 2 connects to fresh air pipe.

As for the oil leaks, tough to tell- I would thoroughly clean and observe seepage or splatter It looks like the bottom of the Turbo and may be the oil like leaking. Just a guess on this one.

Rhag1128, thank you for your thoughts. I still wonder if the directions of the check valves air flow is corrcet - on the picture I put an arrow pinting the direction right now and I would like to know if it is correct or not?
Any ideas?
By the way - #1 is attaching to the engine next to the throttle body and # 2 is gonog to the fresh air intake at the end of it before the turbo.

Regards,

Ivo

Thats right I meant to sat intake manifold... Its not uncommon to have a few drips of oil on the bottom of the TC

One way to confirm flow direction is to remove check valve and suck or blow on the end which ever way it closes is the direction of flow.

Ivo,
It appears that your turbo oil return O ring needs to be replaced. That is the cause for the leak.
