I want to change the piston rings on my revup to fix the oil problem. Should I go new OEM or what is a good piston ring set that can fix the issue?
edit: my engine has 136k miles.. would it be cheaper to buy a new engine? (PS: Im not doing any of this work myself, im planning on paying a shop)

 

Not exactly a cost effective repair to pay a shop to tear down the motor when you're doing it ONLY to fix oil consumption.

At very least I would do a compression test to see how healthy the motor is before spending a few thousand dollars on OC.

 

Oil is cheap!
On my previous 06 G35 6speed I kept it for 171796 miles and traded it in for a 2012 G37 because it needed work.. I just kept adding oil as sometimes it used 1 qt/1000 miles.
I think the op would be just wasting money to replace rings
Just add oil when needed and check it frequently.

Just my $.02

 

Like the other guys said, unless you're prepared to spend a couple grand to fix this issue, it's much more cost effective to just deal with the added maintenance. A replacement engine will probably have similar levels of oil consumption. Only reason to tear the engine open is if you're planning on swapping in forged parts and adding displacement and/or going forced induction.

 

On most engines that we have rebuilt we use cheap rings. The SR20's we use $35 set of Eve rings and ran as much as 26 pounds of boost. Never had an engine fail from cheap rings yet (knock on wood). I built a bulletproof 2AZFE a couple years back and they eat oil worse than any Nissan. From what I have seen most engines that eat a lot of oil either have new style low tension weird design rings that don't last very long or if the engine has standard rings probably hasn't had regular oil changes and the oil control rings are gummed up so bad they don't even work. Sometimes if ran long enough the piston ring relief holes will be totally clogged and need to be reamed out too. A simple dingle ball hone job, piston clean up, head gaskets, and rering job will fix her up good. Doesn't cost much to DIY just a ton of time!
