Please keep this to a standard format so that it is clear. Do not add other text or asking to test drive other ppl's car. It makes the thread cluttered. This thread is ONLY FOR DATA COLLECTION. Use the CU2 pinging thread if you want to organise test drives.

I know that this thread is for data purposes and the mods can feel free to delete this post but I thought I would throw something up for you all to think about.

I am not a mechanical engineer or engineer of any sort, so don't shoot me down, but this is just a thought;

A conventional gasoline engine usually has say a alloy head and cast iron exhaust manifold that is sometimes connected flush to the heat without a gasket, sometimes with a gasket in between, no doubt these two have different properties in the way they are made up and in there molecule structure and have different heating/cooling characteristics....

I was informed that the head and the exhaust manifold are actually one piece on these motors now, despite being a carry over from the previous model.

The point I am trying to get to is, could it be possible that as it is ALL the same piece of alloy, could some of the heat that is meant to exit through the exhaust system be transferred back into the area of the head around the cylinder chamber and be causing the pre-ignition? I remember years ago coming across a crysler/mitsubishi motor that would develop a hot spot in the head and this would cause pre-ignition and even running on to an extend.

Again, I could be completely off track here, but these engines have that many sensors that if it had been a computer/software problem surely it would be able to rectify it....

Let me just say that all 2006 on FD1 & FD2 Civics have the Exhaust Manifold cast into to Cyl Head the same as the the current K24Z3 in the CU2, yet no such problems exist in the Civic. Mind you, they do not run 11:1 compression ratio.
Post combustion ignition within the Exhaust manifold is nothing new. There have been several model cars over the years that have had this problem occurring.
In my belief if this was the actual problem All K24Z3 engines would be effected, not just a few which is the case. I could use the same argument & suggest that if it was an actual pinging problem in theory it would be more pronounced on vehicles with a manual transmission as owners would tend to labour the engine more (not downshifting soon enough) which would place more load on the engine, subsequently increasing the chance of pinging. Pre Ignition has usually been associated with high load / low RPM.
I still believe it is a problem associated with the timing chain / tensioner, but again if this was the case one has to ask why Manual Transmission vehicles don't appear to be effected? Could it possibly be something within the Torque Converter or an Auto Trans problem?
All we can do is wait for Honda HQ to find the problem so that effected vehicles can be rectified.
I have no such problem in my CU2 Auto, & 2 others that I know of personally are not effected either. It will be interesting to find out what the problem is eventually.

I have had a number of discussions with Fair trading in NSW, it seems that whilst everyone here is happy to have a whinge and wait, no one is willing to step up to the plate.

Fair Trading require anyone that has this problem to report it, so that they can exert some pressure.

If you are serious about getting your car fixed, take the right steps!

If you had read through the posts in the other thread that you've posted this comment in as well you would see that most have had the fix done and are quite satisfied.

I did read the other thread, and yes a number of people have had "the fix", but a number of those people still report the problem occuring.

Putting it simply, in my eye's unless the problem is completely rectified, it is still a problem...

It is unacceptable that we pay $$$ and get treated the way we do.

As I mentioned in my post, I have had numerous conversations with a representative from Fair Trading, they are reluctant to take it on with only one formal complaint recorded.

We have 50+ pages on here of people complaining about the problem, and to report it to fair trading is just a matter of filing out a online form, it doesn't even cost you anything to do.

[denot]

All they will do is to set a due date for honda to come up with an "update" status of this issue. This will still continue fo a while but the diff is that honda will have to report the stAtus to the fair trading. Note that they cant or wont make honda somehow magically fix the problem straight away.

Ps: i've said this bcoz it happens to my workplace before. We have report a problem woth our one of our supplier 2 yrs ago. But till todAy it hasnt been resolved.

[blk_shadow]

this pinging noise, Honda refers it as "pre-combustion noise", caused by over sensitive knock sensor

Most people who drive their Euros hard will hardly get this problem compared to the ones who drive it softly.

If you go to Honda now, they will replace your knock sensor and intake manifold gaskets. that will solve the problem.

[blk_shadow]

Dealer says it's extremely unlikely that the knock sensor is faulty without even looking at it. Drive 3 full tanks and come back later....

when did you ask the dealer about this?

Honda has resolved the issue, and the problem is the knock sensor being over sensitive. Honda has sent knock sensor replacement together with intake manifold gaskets for Euros with this issue.

I'm sick to death dealing with the Brisbane dealer here..The dealer I bought with (near a major highway) completely ignore my concern..complain to HA, no reply..went to a different service dept near city, and they say they will get me a knock sensor but have to wait..

Its ashame the experienceI have dealing with Honda after owning several Honda for the last 2 decade...Sad to say this is my last Honda for sure..never buy another 1 again.
