Crack up Upper Timing Chain
First, I can confirm that it is possible to access the upper timing chain bottom bolt on a 2004 545i with active steering. Photo attached.
As stated in other threads:
- Lossen Serpentine Belt
- Remove top bolt
- Loosen bottom and slide to right.
Upon removing the gasket, I noticed what seems like a crack, and not sure if it is significant. If not, do I simply apply a little gasket sealant over it?
Thanks
