Holy crap. :shocked:

Hate to say so, but that does look like part of a piston ring.

 

Looks like a ring...sucks

The local honda dealer that did my rings is no longer... They closed down two months ago. I need to track down the technician that worked on my bike and have a talk. Something tells me this is human error.

If its a ring i hope its an old original piece that had been in there for a while that is just now coming out.. if thats even possible.

It was slightly bent with a kink in it. I wiped the oil off and straightened it by hand to get a better idea of what it is.

 

Oh man! I think you have some problems. Since the dealer closed down, I think you are probably up a creek without a paddle.

 

I was not happy at all with some guy tearing into my honda built motor and "fixing it"
I asked them who will be doing this and they told me "our best guy" with 30 years experience.

Im thinking the operations in replacing piston rings leave plenty of room for shit to go wrong.

The good news is it didnt cost me anything as it was still under warranty at the time.

 

I tried to look at the initial post but cant focus with your avatar.

 

Is there a compression test or something a mechanic can look at to see how much shit im really in?

It runs good to me... maybe a dyno test? You think I lost power at all?

The dealer I plan to take it to is closed tomorrow, so I wont be able to get answers till tuesday.

I paid and signed up for 8 trackdays so far this year amd my first one is this friday may 4th

 

I am not 100% sure how the ring configuration is on this engine, but it could be part of the oil wiper ring, thus your compression would not be effected.

 

Is the oil wiper ring really thin? Because this piece is very thin and I can bend it by hand with ease.

 

Do a compression test. Your bike would run like absolute garbage with a broken ring and the amount of smoke would tell you everything you needed to know.

I have no idea what the PSI should be on one of these motors, but if you see any variance between cylinders greater than 3-5% (if it is a broken ring, that cylinder will be down an undeniable amount)...you should worry.

 

A leakdown test will tell you much more about the health of an engine than a compression test will.

 

+1 on this.

 

That's true, but if that is part of a ring, no need to go through the hassle of a leakdown test.

 

If it is indeed part of a piston ring, my guess is that it's an oil scraper. If a piece of compression ring broke off, how would it slip by the oil scraper below it? It is more likely to get caught between the piston and cylinder wall, or get blown out the exhaust. It might also wreck an exhaust valve on the way out.

Hope you can solve this case. I'm interested.

 

This makes sense. You're the second person to say oil scraper and a co-worker thinks this as well.

Thanks guys for all the feedback. My fingers are crossed. I'll let you know

 

Oil scrapper rings are alot thinner than compression rings. I assum since you stated that it was done under warranty it was done at a Honda Dealer? If so, even though that dealer closed there should be a full warranty on the work performed under said dealer through American Honda.
Old ring or new ring, it should not be coming out...I would no want anything floting around in there.
If it is piece of the oil control ring it should still cause a compression problem in that cylinder over time... the spot on the ring that is broken will wear unevenly and gouge/scratch the cyl walls over time.

Compression then leakdown test is order. I would move quick. How long ago did you have the work done?

 

Yes it was a Honda dealer and I have put about 4 thousand miles on the bike since warrant work was done.

All this above makes sense to me and I really was pushing to run test on my bike and he kept saying test wouldn't show anything... Compression would look fine. I was like really?
I'm no mechanic so Hell if I know. I asked what could happen? Burn more oil or seize up? He said really tough to say.

I didn't really get any answers except it a oil scraper ring

 

I am guessing you got your stuff done at rmc? I would take my bike to I90 motorsport in issaquah instead of taking in to hinshaws in auburn. tell them what happened and they should take care of you.

 

Yes, Rmc did the ring warranty work over a year ago.
Today I went to I90 motorsport, showed the piece to the service manager and he verified it being a scraper ring. He said no way to test it...compression and leakdown would show nothing for this problem. It would have to be taken apart to see what's really going on.

He took a picture of ring and sent it to Honda and waiting to hear back. Still a mystery...old or new ring....who knows. Its running pretty damn goo
d really.

 

If he sent that stuff to Honda, you are covered bro. Did he give you a copy of the notes they took? and what exactly they sent to Honda?

A typical piston has 2 compression rings and a oil scrapper. The oil scraper is made up of 2 rings, an upper and a lower and inbetween there is for a lack of better words a spring.

A compression check is going to check the condition of the cylinder, the compression rings, the piston, cylinder head, valves, valve seats, and head gasket. The leakdown test is going to show you what one of these is leaking. If it is a oil scrapper like a lot think, and i am one of them the compression test and the leak down test will not show anything; a tear down is going to be needed. you may be able to remove the oil pan and rotate each piston to BDC and see if you can see and damage, i don't think you will; but you never know. Your engine will need to be opened up and the pistons removed. At the least your looking at a new set of rings, maybe a piston if the ring. Biggest reason the ring failed is that it wasn't fully seated in the groove when the ring compressor was used. Or the ring wasn't in the compressor all the way and he just smacked the piston in. I gonna say it wasn't fully seated and he forced the compressor closed and did the damage that way. I've done it, but i replaced the ring i broke before i went any further. Stuff happens, but it should have been caught if the guy new what he was doing. I also like to know when they tear the engine down if they staggered the rings?

This....


Honda Has issues like this before it was a problem with the cbr. Google oil burning problems in the B18 and you will know what I mean.
