Timing chain cover removal
 

I’m at the point of replacing my timing chain guides and tensioner. I’ve removed 17 bolts and two pins have been tapped forward from the back. A couple gentle swats with a soft faced hammer lead me to believe something is still holding this on tightly. Do you have to remove the AC bolts and or the PS pump bolts and or the woodruff key to get the cover off? I’m replacing the front seal as well.
I did not remove the oil pan since the cylinder head is off. Looking for direction from someone who has done this before. I’ve not done an m54 but have done other motors. 2001 3.0 m54.

Are there two longer bolts that hold the oil pan to the front cover ?

There are two such bolts on the rear cover

There are 4 bolts all the same length along the bottom of the timing cover on the right in the photo. The area looks like an oil slick from a grounded tanker. I have not loosened the AC bracket or the power steering pump yet.

In the broad daylight I found one more bolt. Cover is off, de-gooed and painted.
