260 Rings$$$

**Flatlander** · 10-22-2021, 08:52 AM

I am getting ready to freshen up my 260 and looked into getting new rings for it. The last time I bought them they were around 400.00
This time they are upwards of 600.00!!! WTH....about fell on the floor!
I contacted an engine builder about possibly getting a discount on the TiN rings. He said he doesn't use those any longer and now uses chromoly black oxide coated rings
in nicasil bores. I thought I would get other peoples thoughts on using those rings. I trust the guy but have never heard of this done. They are much cheaper....

no one has heard of using these rings?

Years ago that’s all Gene Treichel used when building nikisel motors . Who is your engine builder ? Hf…

Ya be lucky to get anything..........

I usually do all my own motor work...I was just looking for a better price on gold rings and that is when I heard about the black oxide coated rings. I don't want to say who I heard this from...don't want to cause a pissing match. I never had good luck with Gene, so I'm not sure that helps my decision.

Yes.. Been in there 2 years. They Work Just Fine

260's originally came with moly rings, TiN rings came out in later 90's to address complaints of early ring replacement. Moly rings seat quicker are easier on cyl plating but do not last quite as long as gold rings.

Thank You guys! I figured they would be ok to use...but of course there had to be a downside to them. I was told they would go 100 hours, not bad. My current rings have 120 on them and still have some life left.
The big question?? Merc rings= $600.00 or Black Oxide rings $200

Mrzip, do you know how many hours are on the rings in your motor?

**Mrzip** · 10-26-2021, 02:25 PM

Quite a few... It's a fishing motor.. I checked compression other day.. No Problems.

Who sells these black oxide rings? Any adverse affects to nicasil?

**Stoker boy** · 10-26-2021, 04:19 PM

Are black oxide rings actually black?

**half fast** · 10-26-2021, 04:29 PM

Yes , they are black. Gene gave me the merc number to order and use but I can't find the part number we used then .I do remember I had to order 6 because they came 2 per pack. hf...

Only thing I’ve been told on the 260 that I’ve used, is chrome with titanium nitrate coating. I never heard of the inexpensive black rings. Are the black rings good for super high rpm motors?
