Installed an extra O-ring inside the oil filter

That's weird, I've only ever got the one (larger) O-ring. Here's the part number for Toyota filter I'm using:

04152-YZZA6

You're probably ok. Seems like the smaller O-ring is meant to push onto that inner piece. That the perforated metal tube right?

If it's driving you nuts, removing the oil filter for a check or whatever, you'll only lose about 200 cc, what's hung up in the filter.

 

The first set of Toyota filters purchased didn't have the smaller "O" ring, or the plastic drainer.
The 2nd batch had the 2nd "O" ring.
WHY won't they include the drain plug seal???? WHY? WHY? WHYYYYYYYY?????

I don't remember which Toyota they are used on, maybe Corolla, Camry, and/or Avalon? Or for
their trucks, but I did use them to change the oil. You have to press the plastic piece in to allow the oil to drain.
I don't not believe they are used on the Prius.

It's cheaper and faster to package a 1 box for all then separate ones I guess.

 

Those are filters for the engine in the Scion iQ. The oil filter cap has a drain hole. You remove the tiny “cap” and that’s where the smaller one goes. The plastic piece depresses a valve in the hole to drain out some oil. It keeps from making it messy directly removing the large cap. The good news is that the filter is exactly the same size, the bad news is that the o-ring does not belong where you placed it.

I’ve actually been using a high performance filter designed for the Prius in the iQ, so I kept the old tool, but just remove the large cap on my iQ because that little o-ring is like $2 at the dealer. I have to clean up a little mess when I do so, but the first time I used an iQ specific filter I did not insert the tool so kind of wasted the effort, oil did not drain out and I ended up with a mess.

Thanks for asking about this. I bought the 10 pack of filters (with drain plug washer gaskets) that was posted not to long ago and they all came with that plastic tube. It made me think I missed something for the last couple years changing the oil when I saw those in the boxes.

So with that...any scion owners lurking that want a handful of o-rings and drain tube thingies??

That would be me. How much you want? The tool's honestly reusable (I think) but not the o-ring...

moto g(7) power ?

 

My Sienna oil filter set is like that, 2 o-rings and a plastic tool, 04152-YZZA1. Have you double check to see if you have received the correct filters?
