Trouble timing a 4.6 or 5.4? TIME THIS!


(Audi B6 - B7 S4)

Just Google "Images for Audi A7 cam timing chain replacement"

 

No problem

 

Looks like the inners of a Swiss Watch!

 

What the hell is that all about???

 

That looks way above my pay grade! lol

 

I'm still trying to figure out HOW MANY chains it has. Looks like 4? One chain driving each of the two heads with dual cams on each (Looks like one cam on each head has a phaser??). And one chain from the crank driving the two 'intermediate' cam sprockets?. And one chain from the crank driving something right above the crank and something else way down at lower left? (what's all that, the oil pump?). Plenty of plastic tensioners to wear out!
