Source for metal oil filter housing replacement?

This was a failed design that Toyota bailed on once they realized the liability issues. Basically, the design creates a situation where the oil change person can use an impact driver to get it loose and then they dumbly use an impact drive to tighten again because its the closest tool at hand, which ends up eventually destroying it. I got a long list of all the design failures in early Gen3 Prius. A total disgrace really. Most of these "advancements" on the list were removed from Gen4 design.

Anyways, your best bet is to buy an adapter, that converts the oil filter back to standard store bought oil filter in its own can. You can also replace part that the crappy plastic canister screws into with the one that uses standard oil filter in its own can. That way idiots with impact drivers can't be tempted to be an idiot. Of course the only way to idiot proof an oil change is to do it yourself!

 

I purchased one on Amazon last year to replace my plastic oil filter cap. The one I purchased is not available, but if you do a search with "oil filter housing cap assembly 15620-40030 with oil plug 15643-31050" you will find some on Amazon. It is good for the 2010 to 2014 Prius and other Toyota models.

I installed mine in October 2021 and it has worked out very well.

There's a link in my signature, what I purchased. Very cheap through Amayama, I think cheaper than US owners purchasing through US online dealerships.

Earlier in the aforementioned thread, a bit more info:

Spin on oil filter | PriusChat

My costs in CDN dollars, in 2019, through Amayama (ignore the wiper blades). No extra charges incurred:



Roughly $90 CDN, all-in.

To circumvent Amayama's propensity to only show you the "correct" parts, I said my vehicle was 2018 model year (which has the spin-on style oil filter)..

 

Searched all over ebay and Amazon, don't know why they are so hard to find now.

This is the little cap that screws on the end.

This is the oil filter housing, but based on the delivery date, I'm guessing it is coming from China and not a US based seller. Note that the Prius is not listed, but the Matrix, Corolla, Scion IQ, Yaris, and Auris are listed. The Prius takes the same oil filter housing as these vehicles.

I don't believe you need the cap. There is a special tool you screw into the cap to drain the oil from
the filter housing. I think it pushes a spring loaded plate so the oil can be released.

 

there is a spin on adapter which looks very robust from BAXTER PERFORMANCE it is number TS-401-BK, it looks great and is $250 dollars. The device was highlighted on the "Two Guys Garage" show on Motortrend TV.

 

??? You can drain the original filter housing by partially unscrewing the original plastic cap, stopping when the drain slot in the threads is at the bottom. Nothing screws into the cap.

 

You didn't read everything...
I was talking about the aluminum filter housing that some use as a replacement to the
plastic on. The one they are talking about has a round flat piece that screws into the top,
or actually, the bottom, that you remove and incert the plastic drain into, that has an "O" ring
so you can drain the filter. So when you remove it the oil doesn't spread all over.

It is not "needed" on the Prius becaus it is sideways and just loosening it will allow the oil to
drain and not making a mess.

 

Did this work as a replacement for the plastic oil filter housing cap?

 

Yes it did. I have installed them on three different vehicles so far (2011 Prius, 2014 Corolla, 2016 Corolla) with no problems.

They basically look similar to the OEM metal oil filter housing on our 2010 Camry V6, only smaller. Those are the ones that pop up when you search eBay, and will fit the ubiquitous Toyota/Lexus V6 vehicles.
