S8 d3 v10 2007 engine torque settings

[audis8tui]

Hi all, Could anybody tell me where to find torque settings and sequence for bolts of the V10. I have striped the engine down to replace number 8 piston which has broken and I am trying to get all the information I need to reassemble while waiting for the delivery. I have tried web searching and found details on every other engine but the V10 seems not to exist. I could do with figures for the head, sump, crank guard, lower block and gearbox. Thankyou

Wow that was quick, thankyou very much gents. I will download the pictures off my camera tonight and put on here. I am still puzzled as to how the piston had a part knocked off. I bought the car cheap with a known knocking noise which I found out from service records has had for 2 years. The dealers had no clue. Last week I dropped the sump to check the oil pump and found two bits of piston which now the piston is out fit perfectly so at least I know there is no more bits of metal left in the block.

Wow they knew about it for two years

Anyway result for you, I look forward to seeing your pictures, I too have an S8 so have a keen interest to see more of the inside the beast.

This is a mixture of removal and trip down, the last picture is the aircon compressor, wondered why it wasn't working.

In some ways i'm envious, i love pulling stuff apart and getting to know its inner workings.

What kind of mileage does it have on her and have you seen anything like wear on things like the timing chains, guides etc, camshaft lobes, big ends etc.

Just try to get an idea of the longevity for these engines

[Delboy]

Are you going to change them o2 sensors before she goes back in, would imagine they are next to impossible to get at when its in

Oh and whats the inlet ports like, much carbon build up? and hows the change over flaps in the plenum?

[Mechcanico Lee]

Is there tell tail marks on the crank web , has the web been clipping the bottom of that piston skirt
Has the engine ingested water , has the engine had a valve to piston bash at some point

It's only done 74,000 and I cant find wear anywhere, the chains and guides are all good. Apart from the metal knocking noise the engine was fine, no smoke noise or leaks
