All I needed was what came with the new valve cover.

Squealing is gone on MAP 5; or any MAP for that matter. Took it out for some adaptation runs, got it to temp; it's all good now!

Thank you for this DIY. I'm going to test tomorrow if its my PCV valve. I already replaced the serpentine belt/tensioner/idler pulley and to my dismay, it didn't fix anything LOL

I was having this same exact problem on my 11' n55 335i since last october and finally had my valve cover replaced a few days ago and the squeal is all gone and car runs like new now. For me even after I turned off JB4 by setting it to map 0, I was starting to have the squeal too. So glad this is fixed now!

Hey vespa, thanks for the excellent write-up. I've just used it to replace a leaky valve cover seal on my RHD 2012 E91. I don't know if it's due to having the steering wheel on the right side of the car, or it being an E91, but I did a couple of things differently:

Best to have a friend hold the socket/u-joint while you work the wrench. Try not to drop the socket, it's very difficult to find stuff in that part of the belly pan. This bolt alone could be a 30 minute job depending on how many times you drop the wrench.
I'm glad to say that with a 6" wobble extension, I didn't have any issues trying to get this bolt out.

Dirt will rain from the bending cowl onto the #6 injector and you won't even be able to keep track of the trauma faced by the other injectors. Don't force anything -- find a way to get it off gently and then remember how you did it so that you can reinstall in the same manner.
I got a bit carried away and removed both wipers, the cowl that attaches to the base of the windscreen, and the right-hand black vertical panel that segregates the wiper assembly from the engine bay. Removing this panel meant that I could lift the valve cover straight up & off the engine without having to worry about it fouling anything. This also meant that it was much easier to refit the valve cover while dodging that super-sharp camshaft bracket.
Refitting the windscreen base cowl did involve a bit of swearing though...

Thanks for the feedback fasterer. I can certainly imagine how completely removing the windshield base makes everything else much easier and it probably isn't much more effort than just partially loosening it as I did. Even the partial loosening involves swearing as that thing just does not want to go back into place.

I haven't heard of leaky gaskets on the N55, did you find the cause?

My cover seems to be on very tightly and doesn't want to budge. Any tips for getting it off or should it slide right out if all the screws are loose? 2011 n55 x-drive e92

edit: Got it, and my project completed

How did you diagnose this problem? I smell burning oil pretty much every time I drive. I noticed a bunch of oil and dirt at the front of my engine (circled in red in the photo). Would the valve cover leak be noticeable near the exhaust (circled in blue). Any help would be appreciated!

Guys, I desperately need your help.
I did this - all was going well - too good to be true. But when torquing up my valve cover, the bolts suddenly went loose as I was tightening (bolt 1 - and it feels like 2 is the same).

Is this normal or have a stripped the thread? I was using a torque wrench but 6 ft/lb is very low and I'm worried my wrench isn't accurate and has over torqued them.

What are my options?

Thanks.

Edit. And now a bolt has snapped

Does anyone know if the VC gasket number is 11-12-7-587-804?

This DIY is positively OUTSTANDING!! only a couple minor tweaks did the trick on my 2012 F30 motor. My stealership quotes $1000 for this. Pelican parts had a $25 gasket. 1/2 a day later, it's FIXED!!

the injector wiring connector advice is priceless.

many thanks...regards, Dan
