oil overfilling issue
Ok, i got a new problem with the car...
i did my oil change last week and i overfilled the the engine... I've read here and there, that it was really a minor issue usually. But i've had a big oil leak.
so basically i overfilled and the flat part of the dipstick was almost completely covered. i've nearly put 5l of oil instead of 4.7 (from what i read in the faq). i've drove a little with it since then and i've had, amongst other issue, a loss of oil pressure. I've looked under the hood, and the sandwich plate where the oil filter is installed was dirty. The loss of pressure happens when the engine is warm. When i warming up the car, the oil pressure start at a little above 4 bars (sorry for the units) then it decrease up to 1 bar but in an heratic ways instead of the smooth decrease of before.
the other symptoms is that it's more difficult to start the engine. From what i heard it's due to the spark plug that might be covered with oiled. Moreover that when the engine finally start, i have a little of smoke.
the other thing that happened at the same times is that i've tried to remove my air pump without success. i've still remove the BAC valve and blocked the hole on the engine with the block off plate and capped the outlet on the intercooler piping. when doing so i've been surprise that the inside of the piping was dirty. I heard it could be due to the overfill of the engine.
next issue, i don't know if it can be related but my boost pressure has changed. Before i was going from -0.4 to +0.6 bar and now it's more like -0.8 to 0.5bar. I wonder if the oil present in the intake or the oil pressure loss could affect the boost pressure.
my plan for the moment, i've ordered a new oil filter, i hope it will not leak anymore. I'll clean the spark plugs and rev a little with the spark plugs off and the fuel pump off to clean the chambers. And i will drain the coolant to check if there is oil in it.
Does it sounds like what i should do ? sorry if that's a bit long, but this oil pressure loss is really scarrying me.

I would think your BAC delete has more to do with your hard start than your oil pressure. Personally, I'd ditch the air pump and ACV, but keep the BAC for driveability.
Your oil pressure "issue" could just be the sender going out or you could have a legit oil pressure issue, I'd test the sender first to be sure though. Are you using an aftermarket gauge?
As for your boost change, I would say a leak, except I wouldn't think you would pull MORE vacuum with a leak.

i took of the BAC cause the hose from the intercooler to the bac was broken and i had the block off plate.
for the oil pressure i have both the original and aftermarket gauge, and both give the same readings. what do you call the sender ?
For the boost i don't know... maybe the the increased vacuum is just because my idle is lower.
