Broken piece of engine?!

My engine's been making a rattling noise so I decided to investigate.

I removed the plastic engine cover, and found underneath 4 squareish boxes with cable going into them, like this:

Problem is, the 3rd one along seems to have totally sheered off.

What are they, is it something I can replace myself, and what are the consequences of having a broken one?!?!

Re: Broken piece of engine?!

Those are the individual power packs (coil packs) for the spark plugs - if one is broken then are all 4 cylinders firing?

I have seen complete sets on ebay.....

Hi there,

As Pascs said its one of the coil packs broken.
The bit broken off is for the second spark, so only 7 plugs are firing.
The other spark will more than likely be shorting to earth on the engine, best to get it sorted right away.

The best thing for now would to be wrapping the broken coil pack with electical instulating tape to help stop it shorting.

Hope this helps

Ok, so not a tricky fix if I can get a replacement coil pack?

What are the effects of only having 7 plugs firing? I've probably been driving around like this for months since the last time reg vardy's messed around under there

Na, not a tricky fix, just buy one coil pack.

There won't be to much of an effect as most cars only have 4 plugs, and the bit that is broken on yours is for the secondary spark and not the main.

Thats p++s poor of them to leave it like that, I would go back and have a moan, its worth a try, if only if they give you a discount on the part.

Re: Broken piece of engine?!

I've now got my new coil pack, but I think I'm missing something trying to fit it.
There's the 2 bolts that hold each one in place, so I undid those thinking it might just lift out - of course it doesnt.
So I then undid the 5 bolts which secure the plate with all the coil packs on, thinking they would then all lift out - it wouldnt budge.
What do you have to do to remove the coil pack?

Re: Broken piece of engine?!

Take the whole plate out with all the packs attached. There should be some hex bolts that hold the plate on ... one with a brown earth wire. (From your pictures there are two in the centre and one at the top edge at each end ... so 4?)

It takes a bit of pulling as you are disconnecting the packs from the plugs and they have long rubber covers which grip ....

You may also need to gently pull the 2nd plug lead off as you go as these aren't attached to the late.

Swap the busted pack(s). The coil packs are held in place by the round-headed hex bolts.

And put it all back in one piece. Don't forget that earth wire!

cheers, Gary
