Leaky Injector Seal - 2006 Honda Accord ICTDI (N22a1 Engine)

[accord_n22]

Hi Guys

Havent posted on here in quite a while as life is so busy with a new born and the Accord has been running fine until now.

I have just noticed a slight issue on the home commute on friday, one of the injectors is slightly leaking. (hissing)

I popped of the engine cover and grabbed a quick video.

See video and a few attached pics

The car still runs fine, and I only noticed the hissing sound today but it looks like it might have been leaking for a while.

I believe it’s just the copper seal that needs replacing, but I heard these injectors can be tricky to remove.

What are people's experience with these. I have contacted a few garages and they are hesitant to take the job on.
What issues will i face when trying to pull the injector out.
Will the injector break or snap? Would it need to drilled out, is that a complete head off job?

At 317k miles and 13 years of ownership - Would it be time to retire the Accord.
It is coming up to 20 years old now, but apart from the injector seal leak the car still runs beautifully

Thanks All

Unless you get a serious drop in the MPG I would ignore it.

Otherwise it is a can of cola overnight, and an hour to check the corrosion on the head surface once out to see if a copper seal will fix it.

Then there is the injector cleaning (scraping the stuff off the sides), re-fitting the clamp without cross threading or finding a helicoil is what the last owner didn't bother to do.

All while bending over the bonnet, another couple of nights of sleep deprivation

I done this on my sprinter van.
Get the engine temperature up to normal before attempting removal.
If you loosen the injector clamp bolt so the clamp is loose but can't break free,
then fire the engine up and the injector might pop loose.
If that fails you may need an extractor tool.
Then it's lots of cleaning deposits off as channel hopper said.
I bought some elongated soft wire brushes to fit in my cordless to clean the injector housing and some carb cleaner.

if you catch them early these don't tend to be that bad, the service interval is 50 000km anyway.
Just done 4 on gfs sedan and they all came out with a wiggle once the forks were out, though she did take it for a longish drive beforehand. didn't let the engine cool before disassembly

I know this works and have done it in the past but it can be risky with a little m6 if you don't know if the last guy working on it gave a **** or not, bolt could be outside service limit, or over torqued. 5nm and 90 deg doesn't leave you much wiggle room

I did not need to resort to 'engine management' to remoive after soaking in cola. The injectors were tight but not impossible to twist slightly then remove.

If you are thinking of it then put a few wet towels on top of the cylinder head before firing up.

Cheers guys for the advise and info

I could feel my back complaining just reading your post. Nowadays I build up a pile of towels and pillows so I can lean on the car and engine.
