Ummm but many are replacing oem rings because they were crap, stuck and led to the burning issue to begin with... Why would one go with oem a second time? Perhaps Toyota corrected them, or perhaps early 8th gens received a bad batch?
I'm close to re-ringing my 2001 1ZZFE Prizm. Just wanted to see what rings other people are using or recommending? (and where to buy them).
Nippons seem readily available at the usual places, any good?
Thanks, Randy
Just curious, someone mentioned that there are tiny holes in 8th gen. pistons that carbon up easily.
When you get one of them out could you clarify if the holes are in the crown? the ring grooves or the skirt.

Much appreciated.
its in side the ring groves for the bottom ring ( the oil controll ring) this is why they have the problem of burning up, it causes the rings to stick and not properly wear/controll oil on the cylinder walls, leading to buring the oil.

Thanks man, I'll be seafoaming the engine shortly and wanted to know exactly where to target. I'm going to squirt about 2 ozs into each spark plug hole on a warm [not hot] engine, let it soak about 8 hours replace the plugs with a cheaper new set of Bosch Platinums burn off the crap. Finally I'll pull the Platiinums and reinstall the Iridiums. What do you think?

not bad idea. i dont know if seafoam wil break it all lose. i would also try cranking the engine over by hand with the plugs out. crank it over slowly so you just a couple of revolutions to get the seafoam down all the way to the rings.
i have heard of a similar process but they used marvel mystery oil. it was on an old farm tractor that had not run in about 10+ years. they poured marvel in it, let it sit for a day, cranked it over by hand, put more in. they repeted this process a few times to free the rusted pistons. about the 3rd day or so, they went to start the tractor. and it started right up, like it had run the day before, but with a bit of smoke from the marvel.
have you ever run seafoam as an induction clean thru an iv style drip?

No, yet i've searched the site etc and I bet soaking the rings and grooves is probably the best, short of an engine job.
This is the only product that actually has proven to clean an engine. It takes time, but is a proven fluid.

I'll look for it but that seafoam is going in first.
Thanks

The 4afe/7afe are plagued with this as well. The 20v I rebuilt had several oil holes plugged up, so I had to clean up the pistons and clean all the oil passages on each piston with a pick and a ring groove cleaner. Lots came out as the previous owner wasn't religious on oil changes.
