Hard time getting valve cover off

Like the title says. Removed all the bolts but just can't peel the cover off. Previous owner did the job also and it looks like the mechanic went crazy with rvt sealant. Seems like it's hard to lift up from the center where the spark plug gaskets are. Just don't want to crack the valve cover and add extra money to this job. Any ideas?

Get a thin blade under the edge and slowly and carefully cut it loose until will come loose the rest of the way. Work around it being careful not to nick up the mating surfaces.

a lot times people forget the 10mm bolt in the center under vvt motor because sometimes it be covered in oil. Double check all the bolts are loose then insert a flat head betweeen valve cover and block and just keep wiggling it around

Thanks got the 10mm loose just hanging in the cover. It's a 2008 328xi with 160000 kilometers on it. My dad suggested tapping with a rubber malet. So he's coming over so I can pry and he works the rubber malet. The worst case scenario is I buy a new valve cover in the process.

Forget to mention where the 3 gaskets are for the spark plugs are. That where the cover doesn't want to lift from. I think the mechanic used a whole tube of rvt in that area.

This "mechanic" sounds like a complete hack. He should not be using rtv on this at all.

+1

and also make sure you unbolt the two bolts, one near plug#1 and the other near plug#6. You need a deep socket. (if your engine is N52)

Blade works, but patience is what you need. Try using a flat head screw driver, and slowly and gently lift up the cover. Start from the front end. It is far easier than what it looks.

I just did this job a week ago.


So some people don't use RTV, and they are fine. using a very small amount of RTV is not bad at all. It helps you during the gasket installation by keeping the gasket in place.
Especially the small spark plug gaskets. you do NOT want to perform this job AGAIN!!! I recommend using a 2 mm bead RTV on the new gasket. I did it the first time, It came of very easily and never had any leak.
I did it again on the second time I removed the cover for sensor replacement.

Good luck.

Finally got it off. Forgot a 10mm bolt in between the spark plugs.

Bought all 3 original bmw gaskets for the job. Eccentric shaft and valvetronic sensor and valve cover gasket.

From pics, already there. As a PM - 328i valve covers go bad - I'd replace it.

Now the clean-up. Do NOT get RTV bits in your engine!

I thought his 2008 328xi (N52KP) had steel Valve Cover bolts which are reusable? Bentley VCG Install procedure is attached. Since you have NO metal/metal seams (such as timing cover), RTV only creates problems, preventing gasket from fitting snugly into grooves in cover. Clean (remove ALL RTV) thoroughly and make sure new gaskets seat snugly in cover grooves.

I used this video for replacing the valve cover gasket. He also talks about how to get it out when stuck. The part of the sealant is also nice. He talks about on how much sealant should be on the gasket and where.
