Rusty Parkplugs

Also, I see the OP is in Germany, and most of his posts are about issues with the CTR.

Are these pics from CTR's in Germany?

By chance are they running that crazy european tune by 7Mod for that supposed 500whp they claim with no modification to fuel delivery?

On Facebook one owner was in So Cal (high desert) and two other owners on the east coast.

One of the owners got the head replaced / Coils and plugs and Honda corporate asked for the parts sent to them for examination (the dealer also advised Honda was aware of a potential issue but no service bulletin or anything at this time). It seems that there is some sort of issue, maybe as simple as a batch of coil packs that don't seal as they should and cause condensation.

Another member (east coast) had the plugs and one coil pack replaced and then the symptoms came back and the same cylinder had water/condensation in it and was looking rusty/fouled. This owner sprayed water through the hood scoop to see if somehow, somewhere water somehow snuck down there and no matter what he did or the angle of spray no water was found anywhere in the bay.

sorry I don't recall names or any more facts, just wanted to update this post with what I did remember LOL!!!

well, then we should all check our sparks and coils often

Exactly my thoughts

There is much aluminum on the car. If “condensation” was such that the water/vapor had a particular Ph balance that would be acidic - then, there would be more parts and pieces of aluminum with similar outcome. That occurrance was isolated.
Believe nothing of what you hear and only half of what you see.

But it wasn't one occurance like you seem o suggest nor where they in the same location?

You also shouldn't just discount things without at least attempting to verify if the problem exists or not. Pulling a coil off a plug is simple and you would notice if there was an issue just by looking at the bottom of the coil pack without even pulling the plugs. I'm going to check mine every so often and if they are good that's great no worries, if you don't want to check yours that's up to you... id rather be safe than sorry though

In absence of any data, one’s choices are limited if the desire is to have no issues. If this indeed is easy to check for and has higher than 50% confidence (chance) of detecting the issue early then this is a prudent exercise - while also building up data. Only until there is sufficient open data can we ultimately make a confident and assertive descision without the bias of the manufacturer.

Maybe it’s once every 1k, or 3k miles.

Personally, I would not pull the coil packs that often. Check them once & if there is no issue/corrosion then they are sealing sufficiently and leave them be. If you are really concerned then have the dealer check them while you are there each time you get the oil changed. Definitely something to be aware of though, especially if the car is kept outside.

Finally took my R out of winter storage today - before I put on all the goodies I bought before putting her away, first thing was to check my oil dip stick and check out the coils and plugs. They looked sparking clean - what a relief, however it only has 250 miles and never seen a car wash yet. But i do plan on checking it once a year, probably before winter storage (any good reason to do it after winter storage though?) And I will report back next time i do it

Guys, just watched a youtube clip from FlyingGato about him finding minor corrosion in his spark plug area too. As he pointed out, the water should be coming down from the scoop, and I am wondering if there is any custom spark plug cover and can seal better or channel the water to the sides? Or, anything like that can be installed directly underneath the scoop for water channeling purpose?

I'm checking mine this weekend for sure. It's been a wet winter/spring in the Bay Area this year.

You really should - I took mine to a touch-free wash today, and there was soap water and even bubbles on my engine cover, and I could see the water was coming from those "holes" under the scoop. Then I wonder how the water got thru the solid cover into the spark plug area and looked carefully, and I found that there is a small square opening in above all the bolt openings on the cover. And, the 2nd and 3rd ones from the driver side would lead the water into the spark plugs!! So, this is a real issue as the water does come thru the scoop. I also wonder if this would happen when the car is parked in the rain? Has anyone done such validation before?

So, I am planning to cover those holes that sit above the engine and I think the best way is to take out the scoop and heat tape them from the top. Would it work? Any better idea?

Meanwhile, we should check out the engine bay every time after wash or raining.

Nice find!

I'll have to check mine as I take my Type R to the car wash several times a month. A weather stripping that can take heat may be the way to go. Something like this: https://www.amazon.com/Mr-Gasket-6323-Inferno-Reflective/dp/B000VTYPFG
