I doubt that you have a timing chain issue
Look who came back
I doubt that you have a timing chain issue
The areas you have marked are where the chains and guides/tensioners are located. There was a good thread a couple of years ago by someone who changed those parts. He did it in the car. I'd drop the engine out to do the work. Probably the same degree of effort, but not the sort that requires a whole lot of turning fasteners a sixteenth at a time due to lack of room.
