Hi there, I am seeking advise on a strange glove test result.


Symptoms (may or may not related):
Putting a rubber glove on the oil fill port results in a lightly inflated glove. When revving up, the glove collapses and it gets "sucked in".
There is visible smoke coming out from the oil fill port.
There is an audible "loudish" "cluck" noise coming out from the oil fill port when cap is removed. When pinching the vacuum hose to the vacuum pump, the "cluck" noise changes slightly, not much just a bit. Can't tell if the noise is louder than the typical D5 clunk.Oil level doesn't seem to change either direction after 1000 miles. see video under this link ( https://drive.google.com/drive/folde...KP?usp=sharing )
There is slight oil leak at cam shaft seal and probably around the timing belt side of the intake cover (hard to tell, hard to clean).
My wife drives it, she says lately it has lost a tiny bit of power and the fuel consumption went up a bit.


DTCs present:
ECM-3000 camshaft position sensor faulty signal. Comes up occasionally.
CEM-1F00 ECM, Software faulty signal. Yellow light, present, recently cloned CEM due to leak issue
ECM-7700 Engine control module - incorrect check sum (since I bought it it is there.. i thought this is due to potential mapping in the past. Can't tell if it has more power than the standard one. EGR is not blanked


Research, repair carried out:
Replaced the membrane on the PCV, cleaned the housing, pcv line in the engine block (was clean) and the pcv hoses.
Cleaned the throttle body, intake rubber hose but didn't clean the plastic intake housing on top of engine, above swirl flaps.


What do you think guys, is the glove test an initial sign of something going bad? Or is this fine?

Thank you.​
