Pass on the cp.

From what we have seen so far they are blow by champions. 2 different engine builders, cp pistons...they like to spit oil and haze out of the breathers.

That won't anything to do with the pistons period.

That probably has more to do with how loose the PTW clearance was and what kind of rings more so than the piston them selves

Worst case throw Mahle rings on the Cp Pistons versus the cp rings.

piston to wall clearance and ring gaps are reasons #1 and #2 for that.

That won't work. Ring sizes are different.

Next go around it'll be mahle's for me.

I run them as well and don't like the blowby, it's the rings that are the problem IMO.

I guess I was mistaken when I was told that by other people.

Cannot switch the rings.

What rings do they send with these Pistons out of curious? Are they regular cast or moly faced ? i wouldn't think it would be a seating issue but sounds like ring gaps could be improved for sure

Most blow by problems come from either improper break in or improper cylinder wall finish. Most forged piston use 1/16, 1/16 and 3/16 rings. There are plenty if choices on rings.

I was told only CP rings will work with these.

I'm pretty sure they didn't do a one off ring design. The cost and other problems from astigma attached because of one ring design would keep them from selling. As long as the ring land height is the same as others and I believe it is you could use any manufacture offering those sizes. I run Seal Power with a gapless top ring. They looked excellent when I took it apart. I will be going back with the same rings except in their M2 top ring which us their best available ring. I had zero sign of combustion getting by the top ring.

The Pistons look good from what I can see. I run 1/16 rings and have never had a blowby problem. I also run more than most pw clearance. I also run a lot of end gap! To tight of end gap and I promise you will have blowby!

Cp Pistons have to use Cp rings, I've tried swapping to other rings since my motor is out and no other rings will work.

Agreed. There is more than likely an assembly issue causing blowby. Blaming thepiston and ring combo is a little near sighted imo!
