Type R Fail. #Submitted #Denied #Unknown

[MoTeC R]

could it have been over revved a few times first?

I’m not sure how the rev limiter works on the canned tunes. It’s a daily driver He’s had it 2 years and 3 months and has 24k on it. He really doesn’t beat on it. He’s barely modded so he doesn’t drive it like a hot rod. I mean he’s barely below the 12k average per year. I obviously don’t ride with him on the daily so I can’t confirm that but I don’t see throwing a piston thru the floor breaking your timing chain. It would make more sense that the timing chain broke 1st to me.

I think the only way to tell whats really happened is when the engine is stripped down and inspected to determine the cause, its all speculation until then.

I agree to that point. I would think the ECU would house the event codes also. It’s just very odd that there’s not anyone else to experience this. Is it true that a broken timing chain would blow up your engine? That doesn’t make sense to me either you would think there would be something in the ECU to prevent that.

If a timing chain snaps the chances are the pistons ans valves will make contact leading to chatarophic failiure. As I said only a strip down will reveal the true cause of what has happened internally and something along the lines of a timing chain breakage will not necessarily be recorded on the ecu .

Looks like a computer glitch.

Couldn't it really be caused by almost anything at this point? Abuse, factory defect, money shift etc...

Hard to be definitive from looking at the aftermath pics. Hopefully we can find the actual culprit behind this at some point.

get this torn down asap and let us know what they find. the biggest impact point appears to be where the chain is but its hard to imagine the chain breaking causing that much damage. unless he's spinning this thing out at some ungodly rpm when it happened. very curious to see what the internals look like.

You have a ton of Honda blue coolant on the bottom of the pan and inside on the oil pump. This 100% involves a thrown rod or broken rotating assembly, cracking a cooling jacket in addition to exploding the pan. The pan is cast aluminum so it doesn’t take much to pop it once things go wrong.

How much oil was in the engine? Honda engines don't just fail, especially after 24,xxx miles. Abuse.

Without pulling the motor and checking the datalogs everything is just speculation. you said it yourself, you dont ride with your buddy all the time. What are his driving habits like when hes on his own? Couldve been low oil, couldve been overreved, couldve just been plain bad luck.

Get the motor pulled apart and have it inspected by a shop to determine what went wrong. Take a look at the datalogs to see if theres anything irregular.

Good luck to your buddy.

He’s dropping off today. I’ll let you know what I find out. The dealership said Honda may want to have a look since this is so uncommon. They tune vehicles all the time with common bolt ons and K Tuner or Hondata so I’m interested as well since nothing is out there similar I could find. The only other driver is his wife and she puts about half the miles on and is most definitely not banging off the rev limiter or hammering down.

Yeah probably a warranty issue. Unless the owner was abusing it and I mean REALLY abusing it by launching, money shifting, revving the nuts off of it while it's cold etc. And even then on a car like the type R which is meant to be driven hard shouldn't blow up especially with basic mods like that, so I don't really think it's abuse.

Looks like a computer glitch.

Anything is possible I am really interested to know myself.

A couple of points.

1. You can tell the vehicle was stopped quickly at the time of the failure. The fluids are all over the ground at the tow site.

2. Odd that the ECU wouldn’t throw a 0341 (I think) is the code for timing belt/chain slip, stretch fails.

3. There were no check engine lights or issues leading up to the fail.

4. So they strapped this monster down to the dyno like it was about to climb the dyno like King Kong up the Empire State Building and it pulls a dominant 0whp/0wtq!

5. Just joking about the dyno but I’ll be sure to keep everyone updated. I’m sure many are just as interested in this one as me.

My guess is LSPI. What oil/fuel was he using? Now SN and SN+ are already old; there are API SP tests for oil.
These guys are trying to talk about LSPI mixed with some some chemistry "show and tell" here, even mention timing chain wear somehow.
The question is whether the chain broke first, or a big detonation, which can also cause the chain to fail.

Aftermarket oil filter and wrong oil is what went wrong most likely.
