Is an 06 CDI less susceptible to black death than an 05?
 

When I bought my 06 CDI, the PO made the remark that, compared to the 05, there was an updated injector bolt design that made the 06 less susceptible to black death. Does anyone know for certain whether or not this is the case? I'd be glad to compare photos with someone who has an 05 if there's any interest.

Just a data point...no black death experienced on either of my '05s. One has 281k, the other 204k. Let me know if you want any pics, and what specifically.

Post the pic and I'll try to take a pic of the same part on my '05.

I just happened to be in the EPC when I saw this question.

Not sure if I can shed any light on the 05 vs 06 issue but there appears to be a couple of variations on both the bolt that holds down the bracket and the actual bracket the holds down the injector.

The VIN I used to access the EPC was from an 06 CDI and according to the EPC the part number for the bolt is 000 990 29 07 - the EPC calls this bolt 'Capscrew with hexal drive' when I turn off the model year filters for 06 there is another part number that also appears 004 990 28 12 and its simply called a 'bolt'.

There are 3 different versions of the clamping bracket listed, the most recent appears to be 611 017 05 39 and there are two earlier versions 611 017 02 39 and 611 016 07 38. The most recent and 2nd most recent version are labeled 'Clamping bracket - forged version' and the first version is simply labeled
'bracket'

So it would appear that there were a couple of updates to both the bracket and bolt. As they say in Mythbusters... I'd call it plausible.

That's helpful, Tim. Thanks.

IIRC another area of improvement is the EGR valve.

Here is what I see.

05 E320 CDI Injector seals
 

I just bought an 05 and it has a problem with the #1 injector blow by. I found that the hold down bolt was loose for some reason. So I bought all the necessary components to do a complete change of the seals on all of them. Even though the audio is bad, I made a youtube video of my experience, still have more videos to go. I saw one online resource advise that the hold down forks should be replaced as well. I did not order those, but did order new screws and also special ordered Honda washers instead of the mercedes ones because they're supposed to be better suited for this. Would appreciate any advice on this issue I will make more videos as I progress ..Doug

My '06 has Black Death

Didn't you sell your CDI or you bought another one afterwards? I looked at 2 CDI's (can't remember 05 or 06) about 1.5 years ago and they both had black death.

Autocorrect is annoying

I sold it and bought a Honda Element.

If it didn't give me Black Death I would have kept it but it was not going to be a cheap fix. Mine was so bad I'm sure all of the bolts would have snapped off and all injectors would be damaged during. Removal

Did you buy it with black death or did it develop while you owned it? What kind of fuel Economy you get on the Element. I hear it has a timing chain, never need timing belt job. All cars should have timing chains or gear IMO. No more $700 to 1000 timing belt job every 80K miles.

The Honda K24 engine used in the Element, later Accords, and CRV's have a chain. No more belt at the expense that you get some "chain whine". Small price to pay IMHO.

My 2011 Accord has this engine with the iVTEC head and no variable displacement (full-time 4 banger) and does ~25mpg in town driving, ~36mpg highway, ~26mpg combined. My manual Civic I had before it did 30/38mpg. Pretty impressive economy from a car as big as the Accord with a slushbox.

I have an 06 and I take the cover and foam piece off 2 to 3 times a year to do an inspection and so far no black death. It takes only a couple of minutes for peace of mind.

I get the impression it is easier to fix if you catch it early before you deeply erode the seat.

I would think that one could smell the heated up cooking oil upon shutdown, as to identifying a developing oil leak?

The K24 is a sweet little engine. It powers our 04 CR-V. The only complaint I have about it, and I'm spoiled now working on MBs, is the oil filter is a spin on type. That wouldn't be so bad except it's mounted horizontally. And it's right over the exhaust pipe.

So you can't do an oil change from the top. You have to raise it, get underneath, try not to get burnt by the hot exhaust pipe, and keep from getting hot oil pouring down your arm as you remove the filter. Then your car smells like it needs a ring job or valve seals for the next 500 miles as it burns the oil off the outside of the pipe.

Other than that, it is a great engine. I had a 85 Civic that blew the water pump and took out the timing belt, learned the hard way about interference engines on I-285 in Atlanta. The water pump started squeaking and I was actually on my way to the Honda place to get the WP replaced but did not make it.

In the meantime we owned about 5 or 6 Hondas between us over the next 20 years, so I had gotten some serious religion about changing the timing belt at 100k. I was pleasantly surprised when I took the CR-V in for its 100k service and was prepared to be separated from the better part of a $1000 for a timing belt job. The advisor laughed and said, no belt on this engine, it's a chain.
