Hi all
When changing the plugs in my 2.2 i found that the 2 long bolts that hold down the coil pack rattled around, i pulled them out popped the coil pack out and found the was no thread for the bolts to screw down into just 2 large holes, is there meant to be something in them ? this is the first time i have looked under here so never noticed it before.
-
just noticed i put this in wrong area :D Doh
-
yes there should be a thread, you can just about see it in my cam cover guide:

-
mine hasn't got those so the coil pack has been rattling round for well since before i got the car.. wonder if i can devcon a nut over the hole that fits the thread?
-
Does it have a 2.0l head on it?
-
sounds like someone has stripped the thread? :o :-/
With the coil in the plug, its fairly secure, but not ideal. Maybe worth tapping a new thread?
-
can't tap a new thread as the holes are way to big, I was told it had some work done to the head before i got the car so could it be like said a 2.0 ltr rocker cover ?

Yup, sounds like its got a 2.0 top head on it, with 2.0 it was coil pack on the back, not coil per plug.
The bolts are only very lightly nipped up anyway, being a boding student i would just leave it ;D
-
are you saying the whole head is from a 2 ltr or just the cover ?

Whole head, the bolts for coil pack go into the head. The cam cover is just plastic...
-
I would never have thought a 2ltr head could go on a 2.2ltr lump, does this mean my car is a 2lr now not 2.2 ?

I've never had a proper look under the bonnet of a 2.0 or 2.2 car. If it did have a 2.0 head on it, then what would these stripped holes have been for if a 2.0 uses a separate DIS pack. ....unless someone drilled clearance holes instead of tapping holes in the replacement 2.0 head. :-/
-
Don't know maybe i should put a pic of the holes on here ?

The head cannot affect the displacement of the engine...

thats a shame might have been cheaper to insure ;D ;D ;D

You're playing with words Jamie ;) Of couse it wouldn't affect the displacement/swept volume, but the term displacement wasn't used. You could alter the engine size of an engine with a a bigger or smaller combustion chamber volume of a different head - I've no idea the differences between engines as to where the extra 200 cc came from. :y :y

If you're passing north Manchester I have some Time Certs you could use. Think Helicoil .... but better. :y :y :y

The question was, was it still a 2.2 with a 2.0l head. The reply is that changing the head cannot affect this.
In the case of 2.0/2.2, the difference is in the stroke.

A lot of expence then, new pistons & a crank just for the sake of 200cc ;)

indeed, but I suspect the changes were made to comply with emissions
-
So, the 2.0L has a single dis pack, I know because I have changed one, but the 2.2 has separate ones, I did not know that...... :-[ ::) ::)

I'm sure it's a single coil pack staright onto the spark plugs ie no HT leads. :y

Ok ;D heres some pics

as you can see no threads.

Definately a 2.0 head! :(

so why are there clearance holes in a 2.0 where there should be thread holes on a 2.2? :-/
Just curious. ;)

He has a 2.0 head with a 2.2 rocker cover fitted. The 2.0 rocker cover doesn't have the clearance holes ;)

Well im confused now so does that mean i have lost the 200cc :-?

No, as TB said up there ^ somewhere the difference is in the stroke of the pistons :y

Ok sorry to ask again but it was starting to make my brain hurt :D I wonder why whoever done the work put a 2.0 head on and not a 2.2 unless there alot cheaper if it was me i would have on there what SHOULD be on there saying that the one thats been put on is so clean it was new or repainted the only thing that looks horrid is the cover as it has lost most of the silver

Your guess is as good as mine, could have been down to price, availability etc. As for the rocker cover again could be they picked the head up without one so just re-used to original. As long as it runs ok with the coil pack pushed down firmly I wouldn't worry too much.

She runs like a dream even with the lamba sensor problem. On a long run like the one im doing tonight of 230 miles i get about 38-39 mpg saying that i don't know what is good mpg for the 2.2 estate as it has some weight to it Even more with me sitting in it ;D. As for the rocker cover i think i might just paint it as it looks crapola like it is.

that cam cover has seen better days!

To difficult to put in words what I'm asking ..... :-?
The 2.0 doesn't have any where to bolt the coil pack to, it doesn't need to. The 2.2 has threaded holes in the head for you to bolt the coil pack through clearance holes in the rocker/cam cover. If you put a 2.2 cam cover on a 2.0 head, then I'd have thought the bolts would have hit a solid 2.0 head with no holes in it :-? :-/ :-/ :-/

I know what you mean ;) The 2.0 has a virtually clear sunken section between the cams with the 4 plug wells in the bottom. The 2.2 has 2 built up towers with the threaded holes for the coilpack to bolt to. Try looking at the 2.2 cam cover HowTo and you'll see the towers :y
-
.... The 2.2 has 2 built up towers with the threaded holes for the coilpack to bolt to. .....
I see now! :y :y :y
so it just need the sunken bits filled with chemical metal and a threaded insert in there. :y

For clarification:-
2.0 = first pic:-

That's a lot of work. Easiest method would be to use a suitable sized one of these:-

a bit fiddly to fit. ;D

Nah :P Bolt through the coilpack, turn the nut on a turn or two, hold the bolt head down as you push the coilpack home then pull up the bolt to hold the butterfly agains the cam cover and nip up ;)
