N18 Engine Hissing Sound and Weird noise (Video inside)
#26
Updates, So I didn't have time to fix it yet. I've driven around 400miles, Both city and urban. And this morning when I was about to merge onto the main road my car sputtered and struggle to move. It then had a really rough idle. I have tons of white smoke comming out the exhaust. The OBD2 says Cylinder 1 Misfire...
I'll get it towed next week... :( sounds expensive to me.. You guys should really get it fixed before this happens!

The misfire could just be a crazy coincidence.

Oh yes! It was sucking air like crazy. I could barley get the cap off!! It appeared to be original as it had all the original stickers. After I replaced it everything seemed back to normal. I spoke with a service adviser at mini when I bought it, he was super cool, I asked him about my intermittent cel. He then started asking me what I was installing and I said a valve cover. He said to expect lower oil consumption, I hope he's right. my R56 drinks oil like its going oil of style..........

Yep. Yeah, I didn't get too excited when he said that. It does use less with the new cover though... I drove 25+ miles with the screwed up valve cover and chewed through 1/2 quart of oil! Service guy said when cover is messed up like that is blows oil straight out exhaust and i believe it! Also said that condition can contribute to carbon build up?

Due to time constraints I bought my cover from the dealer and it came with the gasket installed on the cover and a new filler cap. Driven about 400 miles since installing the new cover and no codes and running great.

I have the exact same sound coming from the second video posted. Just wondering how you found out it was the valve cover and what part on the cover failed? How's it holding up?

I'm still trying to figure out how a PCV valve ended up in an oil pan on someone's car. I ordered a new valve cover for my exe's 2010 R56 Base and the PCV valve is enclosed. I have sprayed the valve on the car with cleaner and the issue went away, so I'm not sure the PCV valve is actually bad.
Is there a suggested timeframe or mileage for replacing the valve cover since you can't replace the PCV valve on it's own? I had P2414 codes for awhile and replaced both O2 sensors. The code was still there so I sprayed the valve and the code never came back. I just don't know if removing the valve cover and cleaning it out really well will correct the issue for the long term or should I just replace it while I have the new cover? Since you can't actually see the PCV valve it's difficult to tell if it is in need of replacing. Her car has around 65K on it now. Any suggestions?
Cheers to all.

Temp solution: drill hole?
A big hello to everyone, my very first post in these forums!
I have the exact same problem as the original poster. I am ordering a valve cover and it will come in a few days......but meanwhile I need to drive the Mini around town, just a few miles at low speed. (Wife needs to pick up the kids from school while I am at work with the other car).
As a temporary solution...I was wondering if I could drill a hole through the oil filler cap, maybe a 10 mm hole. It should relieve the pressure and stop the whistling noise as heard in the second video. That I have confirmed by starting the engine and let it run for a minute without the oil filler cap.
The new valve cover comes with a new oil filler cap.
What do you say about this crazy idea? :-)
