For those of you that have replaced the Valve Cover Gasket...

How was it? Did you find keeping the new gasket in place and mounting it on the block difficult? Its really up against the firewall on our cars. Any helpful tips? I plan to do this in one upcoming weekend.

Thanks!!

I have a few tips as of right now from researching and asking around FWIW

-remove the oil cap and use that hole to gain leverage to remove the valve cover.

-use a spray adhesive to tack the gasket down so it won't move when installing. I'm just using some light loctite general spray adhesive. Something that doesn't clump and is thin, just mask the channel and spray inside. I don't plan on spraying the entire thing, just the 4 corners of the big gasket.

-when removing the two middle strut bolts, pull toward you so you don't smash your windshield with whatever tool you use.

This wasn't that fun of a job, very annoying at times, but I got it done in 4.5 hours. There's a few things us 2 series owners will want/need to move in addition to guides you'll see elsewhere. Getting the valve cover back on was surprisingly easy, the adhesive made the gasket stay on just fine and I checked it with a mirror and all looks good.

About 30 mins driving and the mating surfaces look clean so I think the leak is solved, still some residual oil burning off that I couldn't wipe up that I'll have to deal with, and a little fuel smell, but that's probably residual as nothing seems to be leaking from the lines and considering the pressure they are under I think I would notice it!

Feel free to ask me any questions or for any advice!

When I start mine up, 2014 M235i, I get a slight whiff of oil. Like a drop and the smell goes away quickly. Can't actually see any leak and at 6000 miles after the last change the oil still reads totally full.

So, where do they usually leak and I hear some of the valve covers actually warp. How common is that as if I start the job with just the gasket, I really don't want to have to wait for a valve cover if I could actually see if it is warped.

Any advice appreciated.

Rich your never going to see the warp until its off the car and you use a straight edge and feeler gauge. My advice to you if you are worried about it and plan to keep the car is to order the valve cover and gasket set so you have both. Then when you do the job you can check the cover if it's not warped don't change it and keep the cover or return it

Undertaking this project next week. Would appreciate any F22 tips as all the videos online are showing the replacement on different models. Thanks!

Had to change mine at 57k miles. This really is on the early side. It did not leak much so probably could have gone longer - but it was enough that I could smell the burning oil once in a while.

Job is a bit of a PIA. Not super hard, but there is a lot of stuff to remove. I didn't use any kind of spray adhesive but others have and if (or when) it is time to do this again I'll give it a try. Definitely use a mirror to check to make sure that the gasket is in place properly before tightening it down.

Mine was at 64,000m 2014 M235I. I did the repair but there is still a lot of oil smell coming from the engine compatment. I am hoping it's just residual burning off.
