"? take I do this fk the apart How"



I am trying to replace my coils and haven't got a clue where to start.
Tried undoing a nut and it wouldn't budge so the injectors started leaking.
Are any of these nuts left-handed ?
Can I just 'pull' the cables off the injectors or is there a retaining clip or is there a twist ?

Ta for any time you can spare ?

Sorry, nothing helpful to offer i'm afraid, but couldn't help but notice that little bit of yellow pasta you have tangled up and hanging between your bulkhead an engine. You should get rid of that. I hide my snacks in the drivers door pocket,

Should have bought a 4.2

Ha ha, Simon. Sorry but I love my Tagliatelli fresh, with a hint of Mobil 1

You can remove the coil packs without removing the fuel rail, the problem comes when the rivnuts spin on the aluminium plate that they are mounted too. Long reach Allen keys or bits on a ratchet.

[Shanksy87]

Remove the fuel feed, smaller hex. Pull the rail off by pulling a 45 degree angle from one side to release 4 injectors then the other side should come. You can do it so all injectors stay attached to the rail comeplete with wiring.

Then you can start your argument with the rivnuts holding the coils in place. Would be worth looking at the oil pressure sensor underneath whilst it's out and also the alternator belt. New HT leads also. And new injector o rings. Slippery but necessary slope to go down, in my opinion.

[NuddyRap]

I agree.

Make sure you have a couple of rags to hand in case of any fuel leakage. Stuff them under the fuel rail as you lift it in case one injector is a bit loose.

And try to move the X piece at the end of the fuel rail deliberately rather than as a consequence of moving something else. They are very brittle and snap easily.

Check your big fuse whilst all of that is out of the way too. A bit easier to get to if you have big hands.

Don't pull the fuel rail until you have bought replacement injector seals.

It is technically possible to remove the coil packs with both still attached to the mounting plate (assuming not all six of the plate mounting bolts have been used), but it is far from easy. So the obvious route is to remove the fuel rail first.

However I guarantee you will destroy seals when refitting, so best get plenty of new ones beforehand.

I replaced the coil packs without removing the fuel rail. Just use extensions etc. I undid the throttle linkage to create a little more room though.
Before you begin either way, make sure you label the HT leads and take a few photos of routing etc. Label all other relevant stuff as well.
One of my coil pack screws spun but I found it relatively ok to get long nose pliers underneath to hold it. Obviously I replaced and sorted out the plate once off so that it would not happen again.
As ever with the 4.5, take your time as it is possible!

Thanks for all your suggestions, lads. 'Cept twinkam's

Shanksy, do you mean that once the two fuel rail securing straps are off that everything is push-fit on ?

Cheers Paul, I started to "think about doing this job" yonks ago but was put-off by not being able to find an accurate quote for a source for seal replacements. Got any hints ?

Ta !

Injector seals

Nitrile 70 Rubber O-Rings 3.5mm Diameter C/S Sizes 7mm ID - £3.95 inc P&P for pack of 25

The fuel rail is only held on by the straps. Pretty common approach for a low pressure system to be fair.

The injector seals I chose are correct size made from viton, lots of very similar stuff out there but these seem happier than most with our new higher ethanol content petrol.

Not sure if it was this kit but the guy sorted me with something that worked nicely a few years back.

[Mr Cerbera]

Thanks Guys.

You are STARS !!

(Dirty great big fk-off Crowbar just purchased)

I think 15mm are too large for the fuel rail, you may find they get pinched too easily, I think 14mm are a better fit.

However, no harm in getting both sizes and using the ones that work best for you.

Paul, given that I am the worst Dullo in the known Universe, I can't seem to find a parameter to set the OD (to 14 or 15mm) on the Website address that you kindly provided.

Any hints ?

Ta v.m.

I know they maybe a bit more expensive but for a few extra quid why not support one of our independent suppliers?? Peace of mind, and very helpfull guys on the end of the phone!!!
If we don't use them they will dissapear!! You know it will fit!!

Cheers Simon - just a bit too late - I've ordered two sets from separate sources.

RaceTech did well out of me anyway. I bought the full price Coli Packs from them anyway

Haha, yeah you've got to watch 'em! Sometimes their mark-ups seem insane, so i can understand why people go elsewhere.... myself included. But it's also important to give these guys some business. Not just Racetech, but all of the others too. Look what happened to Clever Trevor and Racing Green! If we are not carefull we will end up with only one specialist and that worries me!!!!!
I'm sure i'm not telling you anything you don't already know Paul, glad you didn't take it the wrong way!
But everyone needs to consider this.

The ones I recommend have a 7mm inside diameter with a cross section of 3.5mm, which means the outside diameter is 14mm.

I have no problem supporting the TVR specialists either, but I'm mainly going to reserve that for specialist items - yesterday I spent £22 on four valve shims, I wonder what the markup is on those. Although there must be stocking costs, them don't take up much room!
