Cam Chain and Sprocket replacement

[PxMetro]

Hi All

I am about to embark on replacing the Cam chain and sprockets on my 4.6 Serpentine with the engine in situ. Has anyone done this lately, and are there any watch outs to advise? I have everything other than the sprockets stripped off the front of the engine in readiness. It’s just the timing I am a little concerned about.

Cheers
