Does D16 engine piston ring alignment work for B16A engine too?

Or should I use this pattern?



Thanks

If you don't have a FSM, you shouldn't be screwing around inside the engine.

However, I'll throw you a bone:

Also - I don't know where you got that pattern originally posted, but it's just dead wrong for B-series as well.

the pattern posted above works very well actually. When the engine starts up for the first time the rings will move around alot anyways. AS long as you don't stack the first and second rings then you will be good. The pattern posted above makes alot of sense, similar to the pattern I used in alot of builds in the past.

OK. You are against TWO other?

OK. So I think Im gonna go with with the pattern on the picture?!

Someone else has oppinions?

If you mean by FSM a manual. Yes I have!

And Yes i've seen that picture on the link like year ago...

**** i didnt even know that existed..i just had all the gaps aligned away from each other

Spacing is not critical.As was said already the rings in a healthy engine spin on the pistons.If they didn't they would wear unevenly on the thrust side (like on a two stroke that has pins to locate the rings) .Pressure is not dependent on line of site so it makes no sense that there would be any compression loss from the gaps lining up.With that said I just evenly stagger the gaps.

B e v - T e c h I n c.

I would start with the two compression rings opposite each other, but they will spin around.

He's saying that it's not the official Honda configuration, and he's right.

You're also supposed to keep the ring ends away from the thrust sides so they don't gouge the walls during break-in.

From what I understand, the idea is to keep the ends away from the thrust side during BREAK-IN. The rings will not spin around within the first 10 miles of break-in when the rings seat.

That is definitely incorrect. It's not about pressure, it's about flow. Do you think it's easier for blowby to flow through a straight shot opening (gaps aligned) or through a series of 90* turns (gaps staggered)?

It definitely matters. That's pretty much the whole theory behind tubular manifolds outflowing turbulent-prone log manifolds.

OK, Im gonna go the pattern that I posted the picture!?

Couldn't decide by your conversations

got a question, the new sets of rings I bought, the top ring has a groove, does this groove face up or face down?
