Hi,

Can anyone recomend me a book or location to find various torque settings for things like spark plugs etc? I've got a MkII V6 if that makes any difference!

Haynes no good then

Go buy dinner for your local stealer

I use Autodata, what specific info do you need?

Well I'm a bit of a noob so please forgive my poor grasp on technical lingo...

I've got a misfire on what I believe to be cylinder 3 - (This is assuming the 3rd cylinder is the same on the old v6 and the mechanic who did the plugso n that one marked them up right. He marked the left hand cylinder as III for some reason, seems odd to not mark that as I unless he had a reason!)

So anyway...I'd like to remove the coil and the spark plug with a more proficient pal of mine who has a torque wrench, but I have no numbers. Specificaly, the torque settings for the spark plug and also this bolt marked with the yellow circle, which I think is the only retaining bolt for the coil (what I hope is the coil anyway!! The black cylinder it's obviously securing...)



Foruatenly I have 2 identicle motors, so my plan was to swap parts from one to the other and see if I can get the knackered one working with known working parts (i.e. the coil)

I'm fairly sure it's that cylinder because I unplugged the lead connected the other 2 and it made the engine very unhappy...but that one made no difference!

Yes, that's the ignition coil for the plug, you sound like you have ID'd the problem correctly, just to be certain, you could swap the possible duff coil for the next cylinder coil, if the misfire transfers to that cylinder, you are certain then.....this is my prefered method.As regards torque setting for that screw, I don't think there is one listed, but i'll check, usually, it is best to tighten those with a 3/8th drive socket and ratchet, then carefully tighten it just past nipped up.I would call it "spanner tight."


Edit, Spark plugs are 25nm (newton metres).The coil bolt is about 6nm, going off an ABS sensor torque setting, a fuel rail bolt is 9nm.
