All done from under neath and pretty easy, might well do a maintenance guide shortly as I need to to replace the lambda sensor on my estate (its stuck so needs the front pipe removing to gain extra access).

Two bolts from the centre section to the cat (note, these can sheer so get new bolts, its worth grinding the protruding thread off and applying some penetrating to aid removal).

Two nuts at the front pipe to manifold join.

And a single bolt securing it to the gearbox mount plate.

This will probably seem like a daft question (but at least its in keeping with most of my previous posts!).

What would be the best way to raise the front of the car? Use of a trolley jack and then axle stands? Ramps? (although the front of the car looks too low to get it up on to ramps).

If so, what capacity trolley jack and axle stands do i need to get?

Jamie,

Just as a note...

When i took the old plugs out, 5 of the 6 plugs were definitely dry. (Although the ends were very black)

The plug in cylinder 4 though did have some oil on the thread. Should this be cause for concern?

Oil on the thread probably means a small puddle in the well from the cam cover gasket leaking.

If the plug well had started to fill up with oil, that may have helped the coil pack to fail.  Any sign that that side coil pack had been removed by dealer?

That side coil pack had DEFINITELY not been removed by the dealer. The bank 1 side came out fairly easily, the passenger side took ALOT of effort.

It wasn't loads. It was only really when i noticed the stripy lines it left on my fingers that i realised there was oil on it.

..or it could come from the combustion chamber, which would be very bad news...

If you look at the coil pack, you will see it has a rubber seal all around - this will have to be broken for oil to go down the plug wells.

It is MUCH more likely to be fuel in the bore has mixed with a bit of carbon on the piston crowns and wicked up the spark plug thread, remember that the gas tight seal on a spark plug is the washer that mates on the outside of the head.

Nicely points towards the failing coil pack though.

OK, I guess I need to see one of the DBW engines.  I don't understand why people talk about two separate coil packs, one for each side, and then also talk like it is an individual coil-on-plug setup.

Fairly simple, each plug has a coil (unlike the DIS system where one coil drives two plugs) and the coils are housed in a coil pack (3 for a v6 two off, one per bank and 4 in a 2.2)

I get it, it functions like an individual coil-on-plug setup, but they decided to use more plastic and join them into one block.
