Chewing seals

Car is 2008 e90 320i man on 150k. Cover off at 2pm on a Friday. On the drive home lots of magic smoke began its escape from the bonnet. So I went straight to the garage to investigate.
Tappet cover off and voila. A section of seal all minced up.

Is this damage from over tightening or just a manufacturing defect? Can one really over tighten a tappet cover to squash the seal so?

On the plus side, the engine is pretty clean for 150k.

Big ups to Multi-Tech Auto for doing the job as I type this.

So, anyone? Can a tappet cover be over tightened to the point of rupturing the seal? Really curious here...

No doubt that seal was pinched upon installation.


Did they reuse the original tappet cover seal?
