How to remove N52 valve cover

Big_CG · 09-08-2014, 11:47 PM

In the process of doing the gasket, have the valvetronic motor and everything off. The damn ignition wiring harness plastic guide that holds all the wires is in the way. I removed the ECU box cover. Still cant get the back of the valve cover to clear that wire harness plastic piece. Any secret that Im missing?

It was a long time ago, but I recall when I did my VCG, the back of the valve cover was getting hung up on some piece (close to the windshield) so I got out my handy dremel tool and notched out a small 1-2 inch section of plastic that the weather stripping fits over and I was able to wiggle the cover out... Hope this helps.

that whole harness piece comes off pretty easily. the instructions are in the guides for changing your spark plugs if you search for that.

Ahhh I remember this job. I used this forum posting, it helped a lot. Someone made a video which was helpful.

It's a major pain in the A. You just have to keep angling it and wiggling it until it works it's way out. Have fun putting it back in while keeping the gasket in place too.

Good luck.

Won't that cause leaks.......

It comes out without modifying your car.

MBP0202 · 09-10-2014, 02:23 PM

Haven't noticed any leaks, it's just a plastic outline for which the weather stripping just fits over. Maybe the stripping is absorbing some extra water, but I've never noticed any leakage that has landed on the top of the engine cover from where I made the notch...

It just made it easier to get the VC off and a heck of a lot easier to get it back on without having to worry if the new gasket was staying in place while I put the valve cover back on.

Lucky the N52 (non KP) uses a metal type gasket, and not the rubber groove type that the 2007+ 328i uses.

Big_CG · 09-11-2014, 12:46 PM

Ended up getting it off. Best way is to remove the plastic ignition harness cover so its just the wires hanging there, then the VC comes off

iDriveanXi · 09-12-2014, 09:01 AM

I did mine the other day and it was a bitch to get off too. Hope installation went well for you and no more leaks.

Taskmaster · 09-12-2014, 11:13 AM

Is it really that bad? Tell me that it's the worst part of the Eccentric shaft removal, and it's a 3 hour job, and I'll be fine.

Big_CG · 09-12-2014, 03:34 PM

Its fine. Just be sure to remove those plastic upper and lower covers of the ignition wire harnesses. I struggled with that when it was connected. Not bad once you get that off.

Be sure to torque the bolts back up evenly and to the proper 63 in lb+90 degrees in a criss cross order

Taskmaster · 09-12-2014, 04:15 PM

I don't have a torque wrench. This will be fun.

hassmaschine · 09-12-2014, 04:36 PM

63 in/lb is finger tight anyway. the point of using one in this case is so you don't overtorque them.

alternatively, the HF torque wrenches are actually pretty nice, and usually you can get one for under $20.

have a link?

Actually, I'm all ears for a reasonably priced tool set.

I didn't torque my bolts and have no leaks. 7 ft lbs is not much at all just use your head when tightening. If you hear cracking plastic then you know to back off on the others haha. You'll be fine, good luck.

When you say criss cross, do you mean corner to diagonally opposite corner like wheel torquing or do you mean from one side to the other side alternating like a "Z"

**** CAPTAIN SECRETS IS HERE ****

Drop the subframe and let it hang on the middle 2 bolts (long ones) it will give you about 2 inches of clearance and makes the job a piece of cake

simpleM3 · 10-07-2014, 04:32 PM

When installing the gasket, are any sealants or lubricants necessary for this job?

bernard54321 · 10-07-2014, 04:41 PM

No use only the gasket, and make sure both mating surfaces are dry

You may use something to hold the gasket in place while you move the valve cover but dont use to excess

simpleM3 · 10-08-2014, 12:00 PM

Thanks. Do you know what the torque specs are for the VC bolts?

bernard54321 · 10-08-2014, 01:51 PM

Not off the top of my head, but to be honest i dont think ive ever torqued vc bolts.. just tighten untill they stop and turn 45-90°

Maybe ive done enough of them that i know the "feel" of a tight bolt... if u feel unsure about the torque, i can get you the exact number but it will be later on today?
