Gday peeps, I have a 2004 SV6 I’ve just replaced the timing chains and just got it going again. The code that came after a few minutes of running was Ignition coil cylinder 6 circuit malfunction. I have new sparkplugs and new coils in place. It’s a little disappointing but I guess it’s only 1 code compared with many before the new timing chains replacement.
any ideas appreciate. Cheers

Did you have the CYL 6 error prior you doing the chains ?

If not,
One would assume its something that hasn't been refitted back in place correctly,
Injector plug ?
Coil Plug ? (check the pins)
Coil (check its not split)
Spark Plug needs cleaning re-gapping ?
Check the multipin connector at the back of the manifold ?

Not that code, no, it just seems it will never be code free

What Code is it ?

Could be a simple as a sensor not operating, as its out of spec.

Unless we know the code,
its needle in a hay stack, and anyone's guess.

Ok the code is P0356-00. I checked the brand new spark plug in cylinder 6 and it appeared to have a crack in the ceramic base and changed to another plug. I deleted the code and started up again went for a drive and the code came back after about 20mins. I,m beginning to doubt myself with the replacing of the timing chains as it was 1st and last attempt. It’s running but a little rough for my liking. Anyone else done the timing chains?

Yes, I have done it twice on my LY7, not because it was out of sync,
But I will fess up, the first set was a from CrapBay,
lasted 10,000 k's :(

The Second set was from Repco, that was 35,000+ k's ago, idles & drives perfectly.

For what's its worth,
Maybe pull it down and get a set of CAM Locking tools,
Best kit for your kit !
under $20 from Mace.

Just make sure you order the correct ones for your engine.

Yes I used a Mace kit with the locking tools, did the stage 1 and 2 deal. I’m pretty sure I did it right just unfortunately I have a new code. I have a good quality reader, so I might have a crack and isolate each ignition coils. Also i might try a auto sparki.

With the tools,
you don’t need to do the Stage 1 & then stage 2 rotations.
When the cams are locked,
It’s all straight forward from there.

MHA -
Rotate the crank to stage 2,
Fit the cam locks,
And remove the chains & guides/tensioners,
Replace the oil pump while it’s pulled down,
Fit bank 2 chains and tensioner,
Then Crank chain and tensioner,
Then bank 1 chain and tensioner,

May need to jiggle one/two of the cams with a 19mm open ender,
And the rest is re-assembly of the hardware.
Replace the oil & filter, as it will possibly have coolant in the sump.

Then fire it up, hopefully it will idle a bit better.

I know you have already done the chains,
But just explaining the process to make it easier if you wish to full it down and check the chains.
