Where do you engine builders place your piston rings? Do you use the Honda factory placement, the piston manufacturer's placement (for aftermarket pistons), or your own tried and true placement? Just curious.

 

I use honda placement

 

I used JE's ring placement, and I had oil control issues. I changed to the Honda ring placement, and it got better, but it was still unacceptable. I then tried what I thought would work best, and oil control is no longer a problem. I was just wondering what everyone else's experience was, and what worked for them.

 

Would you mind sharing what worked best for you.

I've built 5 or 6 N/A motors with b16a and b16b pistons running the Honda placement and really tight wall clearances and its always worked out great. I'm building a motor with Wiseco pistons tomorrow and am curios to see what worked well for you.

 

With OEM Honda pistons, stock bore or 0.25mm over bore, the Honda piston ring placement worked fine. With my sleeved GSR blocks, running only JE pistons, I have had varying degrees of oil consumption with JE's and Honda's ring placement. So I took my pistons out and repositioned the rings as follows: say the exhaust side of the piston at the most forward point is 12:00. The top ring gap is at 7:30. The second ring gap is 180 degrees away at 1:30. The top oil ring gap is at 10:30, the spacer is at 7:30, and the bottom oil ring gap is at 4:30.
Before, if I revved the engine, I would get some blue smoke. Now, even when revving the **** out of it, zero smoke. I have another engine that I am freshening up, and I am going to use this ring placement, and see how it works out.
By the way, the ARP funnel type piston ring compressor is one of the best tools ever made

 

thanks for the info

 

what are these guys talking about here in this conversation. Im not completely new, I do know about basic engine theory. It just that I plan on building the bottom end of a b18a (obd1) and this sounds important ttt

They are talking about the piston ring gap placement.

 

oem pr3's and i used the Honda placement. daily driver with no consumption.

 

Nippon Racing P28 pistons, NPR rings, .020" over, OEM ring placement, and it seems to be doing well.
