So i changed my D17 piston rings almost a year ago or a year ago now and i just found out that the rings didn't space properly. I didn't put the gep at the right location where they need to be. I should be able to just take off the head and reuse the same rings and put them in the right order?
also i didn't break in the rings either because i didn't know that they required a breaking in process..

Piston rings are cheap. Even if they looked okay, I wouldn't run the risk of compromising your engine over it.

It's better to spend the money while the engine's apart than it is to have to reassemble the engine, realize the rings are shot and have to rip it out again.

ok, well,the rings are new from honda when i put them in. They cost me a lot of money to. But since its just a year since i put them in i was weighing my mind if i should reuse them.. It will cost me about $180 for the set of 4.

That's ultimately up to you. Like I said, it's not worth the risk to me. You may change your mind after you start disassembling.

yeah. You think you rings on eBay or worth the risk of buying.? I dont trust some price on eBay parts. They said genuine honda parts but the price to cheap sometimes.

 
Rep Power: 125

eBay's okay for aftermarket stuff but I wouldn't do it for OEM. Buying aftermarket rings isn't necessarily a bad option either.

Take a look at this. I think I have the EX selected here but it gives you a better idea of price.

standard sized set (p/n 13011-PMM-A01) is like $42/set plus shipping at majestic honda if you wanna go truly OEM. Oversized sets are cheaper (like $37-38/set)

edit: prices.

yeah, i rother OEM. Majestic honda or (Honda parts now). They have price difference. Thanks though.
since you wouldn't reuse the rings, lets get new once.

Is it consuming oil?

 
Rep Power: 0

no its not but i got the book after i changed the rings. what the book shows me on how to gap the rings, its different from how i gap them and i dont think i have the compression that i had before. I didn't know nothing about break in rings either so that wasn't done also.
and i didn't know that i should put the rings down in the cylinder check the gap with the feeler gauge before i installed them. And one last thing, its the same feeler gauge that use to do valve adjustments is use to check the ring gap? I just want to do it right. And when i was doing the rings noticed a slight burn in about 2 of the rod bearings so i might just change those to.

It said general engine overall but Those this illustration works for SOHC and DOHC as well.? . Its just rings gaping I'm talking about mainly.

If you're not burning oil do a compression check. If it's within spec I wouldn't worry about it. Redoing piston rings is a lot of work.

-Yes you put the ring the cylinder first to check the end gap using a feeler gauge.
-Yes you should have orientated the rings like in the picture.
-Lots of people have different opinions on ring break-in procedures. Some say none is needed, just don't use synthetic oil at first. Others say you must use break-in oil and drive a certain way after startup.

so i found these on eBay if you dont mind tell me if you think its good choice. Also, most of the ring set i found are 75.00mm and my bore is 75mm. Is 75.00mm can be use?.

and please let me know if 75.00mm rings can work instead of 75mm.

75mm and 75.00mm are the same measurement...............
you need to file them for proper clearance anyway. Ffs

if you think that the informations that im trying accomplished are too much for you then you dont need to reply to any of them.. The forum was created for questions and answers..

If you need a forum to tell you that 75.00 and 75 are the same thing, I’ve got some news for you.

I wouldn’t buy the rings you linked. Riceboy’s linked genuine Honda ones. You already said you wanted genuine Honda.

i read some people questions and they make no sense so if you or colin think thats a foolish question well, search the forums. Thanks in return.

I'm sorry, that post was meant to be in jest. I say that to everyone, in person and online. I'm a huge smartass, admittedly

"if it makes sense, we don't do it" is something I say pretty much on a daily basis

edit: to add some real answers to this thread, OE bore is 75mm. Honda also sells .25 and .5 over bore (75.25 and 75.5mm). I've never had to use bigger than OE, but I'd imagine over time, plus repeated reconditioning of cylinders, you're gonna lose material, thus warranting the need for stuff meant for larger bores. Need a visual for .5mm? Pencil lead, my dude. now cut that in half and that's the increase in radius. It's not much, but tells you what tolerances you're working with

ok..it wasn't you that used the word. It was colin42 but its kool.i will just get the rings from honda. Its 42 bucks for each cylinder. And they seem to be carbon steel which should be the best.

If you can find the correct place to post first...
I had to yet again move your other thread out of the DIY section.
Yet. Again.
Mathematically, 75 mm and 75.00 are exactly the same thing, number wise. Makes difference in Engineering expression, numerically they are the same. Physically as well.

Also, everyone answering you here are either moderators or administrators of the forums. Keep this in mind.

i already know someone answered. I'm done with that 75-75.00mm thing. It was one guy replied with some frase that i didn't like.
