Coil pack won’t go all the way in? Help!

[Oxxa]

The caps are impossible to get out, do I use penetrating lube under the dust seals?

@Oxxa The search feature will help you with many questions.   Here's a thread that has extensive detail on spark plug removal and a mod to make subsequent plug changes easier.

I have studied that thread in detail and there is lack of info on pulling the coil pack. Some videos make it look easy and some recommend penetrating lube.

 

so i though i would post here it anyone had any experince on this issue?

 

i tried pulling it out with my hand but its impossible.

 

can penetrating lube cause any potenial damages?

Try the block of wood method I posted about or a wooden hammer handle noted on page 2 in a post above mine on the same page by loxsmith.  Lube wasn't necessary for mine as it's all about getting the right fulcrum to lever the caps out.

Does this mean that you placed a block of wood under the screwdriver and pushed down?

My method for getting the stuck coil packs out was to use a short 2x2 block of wood and a long screwdriver to gently lever them up

Place a block of wood on the cylinder head, place a long screwdriver on top of the block of wood, place the screwdriver tip under the coil pack ( arrow tip drawn in pic) and gently press down on the screwdriver to lift the coil pack up and out.

The block of wood is used as a pivot point - the screwdriver the lever

I doubt penetrating oil would be of any benefit. Just make everything a slick mess except what you're trying to unstick. The "stuck" portion is likely the rubber to sparkplug insulator interface and doubt you could get oil to it with them installed.   Using a lever sounds like a plan and something I've done in tight spaces before when pulling coils off plugs.  I haven't done the ones on my T7 but also give them a twist before lifting. It helps on some styles but not on others. 

 

Use Silicone on the boot when you put it back together to make it easier next time.

Any ideas for levers?

Just what was suggested. A screw driver levered via a pivot made of plastic or wood. Perhaps you could carefully drive a wedge of sorts under it instead? Don't forget to try to twist it first. I don't know if its the case with these but on many a twist will "unstick it" safely and then you don't have to use as much force to get it to lift out.

Worked perfectly. 
 

i finished the job and put the coil packs back in. The left one is all the way in but the right has this mico gap and wont go in any further. They are both lubed with silicone.
 

Should i be worried?

If you have the new sparkplug fully seated and that's as far as the coil wants to seat I'd say it's fine.  (From the safe distance of my PC...)

New Spark plug is torque wrenched at 13nm.

Also i have tried lubing it, levering it down with a screw driver, pushing on it from the top with a long metal bar, etc. it wont go in any further

Hello guys,

 

recently changed my spark plugs and the right coil pack has this gap and won’t go in any further, it is lubed with silicone grease and I have tried levering with a screwdriver and many other things but it won’t move any further down.

 

if it makes any difference, the spark plug is torque wrenched at 13nm

Well i need to solve it so give me a break

[Hibobb]

Can't tell from here, looks like you have to take it apart again to find the issue.

[AZJW]

Threads merged, same subject. 

[Oxxa]

Today I peaked again and it seems like both of the coil packs have the same gap.

 

could any of you guys confirm if you have this small gap too?

Regarding removal, not the current issue, I usually use angled needle nose pliers like this.  And maybe against a piece of wood or something.  However, not this exact one, I have a pair a bit larger.  I just pulled this up as an example.

This is even better than with a screwdriver, cool!

Before you go levering against delicate and expensive electrical components, there is a much easier way. There is a drain hole for the spark plug tunnels located under the header pipes on most models.

A squirt with an rubber tipped air gun and a gentle twist of the caps will free the most stubborn.

A small squirt of contact spray on the inside of the plug terminal and some silicone spray wiped on the outside makes installation a breeze.

I have seen a fair few damaged coil caps from levers in 20 years spannering.

[Lewie]

Maybe they fixed themselves?

[Oxxa]

In the beginning I played with the rubber caps putting my finger under them and such… turns oht they are in place but they lost their shape a little so that explains the gap.
