Hello Guys, i have 2012 civic and need rubber on the top of coil plug hole, seals or whatever they called (marked in picture below) i did search a lot internet and cannot find where to buy only those rubber, any idea where to buy or give me some correct name for it to make another search?

 

[Fantastical_]

You sure you don't have to buy that whole thing?

ya, i was in service and all plastic parts and top electric things are all good, only rubbers are damaged and need replacement, i did search local market physically, all over the internet and everywhere i do find whole things and i don`t need whole things and trying to find only rubber to save some $$$...

Sometimes you just have to bite the bullet and buy an assembly when you only need part of the assembly. I see this every day.

Highly doubt the piece your looking for is sold on its own.

sad

You need the whole Coil pack. The rubber seal isn’t sold separate. If you really want to save money, buy an aftermarket one, swap it.

what is aftermarket one? like something not original?

 

[Fantastical_]

Aftermarket means a non factory (OEM/Honda) product or part.

Ya, as i thought, i was offered rubber that fits phisically to my coil plug holes but i didnot brought , was hoping to get oem rubbers... seems like I'll go and get those

Thanks guys.

I agree it looks like it's not sold separately, need to buy the whole coil, unless you're talking about the other rubber, marked 3 in the image.

nah, sadly not that...the one on the top of coil itself as marked in picture.
----------------

I did brought non Honda rubbers that just fit in size with my coil and changed them. i`m not sure but seems it helped, car was vibrating at low RPM and today it was all fine without vibration.
just need to pray those non Honda rubbers will not damage fast and will be normal quality

 

[Fantastical_]

The whole car was vibrating? What led you to believe this piece was causing it?

on my own i do not have knowledge and understanding of cars, i was in service and after checking and diagnostic technician told me to in first place replace those rubbers, they "leak electricity to walls of that hole (as i understood, something like that)" and pistons wasn't working properly, when car not moves it vibrates even now, and that is some other part need to change, TRANSMISSION MOUNT SET or something like that English name, but when it was vibrating during drive on low RPM technician told me that those rubbers MAY help as they are damaged (as i explained above)... idk i hope he knew what he was talking

 

[Fantastical_]

Oh ok. I hope he inspected the spark plugs too. If the porcelain/ceramic insulator is cracked, electricity can leak out the side and cause cylinders to misfire and make the engine less balanced.

ya, he removed and did check spark plugs too and told they are in good contidion, also guy from whom i brought car told that sparks are are new
Thank you.

Sometimes an old or rotting muffler or it's securing bolts if they are loose can make the whole car feel like it's vibrating. I'd get under there and check it, just for sh!ts and giggles.

will take a look on that too, thanks

 

[Fantastical_]

It's probably misfiring.
Change all 4 coil packs.
They're cheap these days.

Thanks.

-------
What problem can cause misfiring? (except slight vibration i already know)
what kind of problems can occur if not change and run car that way?

 

[Fantastical_]

The rubber insulator all cracked can not give enough spark and therefore misfire.

You can replace all 4 but a misfire would easily show itself with a flashing cel under acceleration.

I dont understand
what problems it causes to the car? will it blow up engine or some major damage can occur if left as it is? lets say if i`ll drive in that condition around 2000 km?

 

[Fantastical_]

A misfire can result in unburned fuel to that cylinder, resulting in oil dilution from that cylinder down to the oil in the crankcase. This causes excessive wear to the rest of the engine.

A bad coil doesn't necessarily present as a seat-of-the-pants misfire. Sometimes it's just reduced performance and gas mileage.

thanks

Hey guys,
I decide to remove all plugs and clean with some special connector cleaner all the connectors, coil plug holes, spark plugs, wires that connect to them... maybe something like rust or dirt is there (simplest option to do i think), but i`m confused is there any connector at the bottom of the spark plug inside engine? or that part just sit`s down without conecting something at the bottom?

and if yes how do i clean that part in the engine? without dismantling engine of course

 

[Fantastical_]

If you are talking about cleaning the part in the red square, just unscrew it and pull it out. Should be an 18mm socket.

That's the part that makes the spark that ignites the air/fuel mixture. It can be cleaned in a small variety of ways. I've used some fine emery cloth followed by a shot of brake parts cleaner to remove residue. Careful of your eyes. And wear gloves.

Be careful threading the spark plugs back in. Don't cross-thread them. Very bad.

Do it by hand, or with just the socket, and possibly an extension, on them and no handle. If they thread in that way with no resistance they can then be tightened up with the handle. If you don't have a torque wrench, tighten them until they seat, and then about another eighth of a turn. But get a torque wrench.

Did I say to get a torque wrench?

I did clear those parts and gonna leave that out of car for all night to "drain" all the liquid if some left inside just to be safe

+ the cable in the engine that plugs in that connector i did also cleared

I got this cleaner special for contacts cleaning

and gonna use that as well on the spark plugs,
i did buy special spark plug removing wrench today, so i think remove and install wont be any problem, also I`m disconnecting the battery before removing anything

maybe i wrote something incorrectly,
do this part in red square touches something inside engine? is there some connector or it just "hangs in the air" down there and it not connects to anything?

 

[Fantastical_]

No, it should definitely not touch anything. A spark jumps across the gap and ignites the air/fuel mixture.

Check the gap while you're at it. Spark plug gapping tools usually have a gauge built in. I don't have the spec handy at the moment.

That is good if no connector on other end, thank you.

ya, gaping tool i saw in some videos as well and forget to buy that thing... i will try to check just with some normal rulers and carefully increase/decrease with some plaiers if gap is big/small

Thank you Scotty, you are very helpful

 

[Fantastical_]

Thank you.

Buy a gauge. A ruler won't be nearly as accurate.

There are other types, but I prefer this one.
