What type rings y'all recommend?

Regarding ring material, what do you all run? Just reading on another forum a discussion of break in procedures on rebuilt engines.


using moly rings you should be broken in about 30 minutes after the engine is fired . If you are using chrome rings then you'll need a LOT more break in time if it ever fully seats the rings that is. Cast iron will break in as soon as its fired .


And that got me to thinking, I've never heard anyone discuss ring material in their turbo engines.

I'm using the rings that came with my pistons. The 2.5 is running Moly rings, and the TIII will be running cast iron rings(just standard replacement units).

I personally don't have a preference unless it will be used in a very dirty/dusty enironment which I've heard chrome rings are well suited for.

Moly, I always buy hastings. They seat right NOW

I use the replacement perfect circle.

Moly of any brand, Hastings, Sealed Power, Perfect Circle, OEM etc are all good. Cast can't take the heat and will melt or shatter with detonation.

+1 to Simon- Must use at least Moly in a turbo engine. Cast will not last
+1 to Ken- Hastings seat NOW if not very very quickly.

Ditto on chrome for dune buggys, dirt bikes, tractors, and D9s.

Moly or iron for me.

I've seen chrome flake off of ring faces, leaving a low spot in the ring (loss of compression) and then work its way past the oil ring, get stuck in the relatively soft aluminum of the thrust face of the piston, and then cut/polish a low spot in the cylinder wall. The flaking may relate to poor pre-plating metal prep or from the plating's embrittlement of the underlying ring material.
