I did all of these jobs last year with the engine still in the car. New full Camshaft chain adjuster units. Very expensive for the two, approx £1500 for the two plus £100 for 2 new chains, and that's just for parts. I know that we can just replace the pads but my pads were fine. The adjuster itself on the drivers side was not functioning correctly. It was extremely rettly until the engine warmed up. There is a theory that the detent pin that holds the tensioner in the start position fails and so the tensioner is free to rattle on first startup until engine oil pressure builds up. For me, the rattle was just unacceptable.
The most difficult and frustrating job I did at the same time (with the engine in place) was the plastic oil cooler pipe. Access is really tight. I generally enjoy working on my car but I hope I never have to do that job again.
I have no idea of how long the job took though I'm afraid. I never rush my repairs as its a bit of a hobby so I spread it over a few weekends.
