Oil Filter cap conundrum

I bought a metal housing and realized that I had foolishly installed it incorrectly. I threw away all the components of the original plastic housing (tube, spring..). I’ve been running it for about 2 weeks and I want to remedy this.

I know my options are to buy an OEM plastic housing and either install it or swap the guts into the metal housing but my question is this -

should I bite the bullet and buy a $90 plastic housing from Toyota ($120 at my local dealership)

Or

is an

$75 Toyota Oil Filter Cap - 15620-0S010

aftermarket plastic housing suitable in this case. listing says it’s OEM, but it’s surely not, surely it can’t matter much. I even see plastic options for like $16.

I know that a strong argument can be made that the OEM composite material is best and that the tube won’t collapse etc etc but how can toyota themselves only charge like $30 for an OEM aluminum housing and $120 for a plastic/composite one?

I realize I made a dumb mistake, but does it have to be a $120 mistake or can I remedy this with <$50??

 

Why do you say it's not OEM? It list it on the description and if when you get it its not OEM then return it. Me personally I stuck to OEM when I did my aluminum oil cap. I actually stick to OEM on a lot of things. Lots of garbage out there these days.

 

It’s half price what the dealers charge, one reviewer said it’s not OEM, and Amazon is notorious for counterfeit products. Since I threw away the old one, I have to frame of reference for returning it :/

 

When I got my OEM aluminum from Amazon, it was legit. I mean you could try. Nothing to lose. You would be amazed at some of those reviewers and the stupid shit they say.

 

thanks for replying to my post btw. Do you think I’d have problems if I bought a cheap aftermarket plastic and put it in the OEM metal housing I have on currently?

 

The spring and tube are critical components. The spring is rated for a specific pressure and allows bypass if the filter begins to become clogged. With the wrong tube length, the filter can collapse. The filter housing material don't matter much.

 

I wouldn't buy an aftermarket one. I would buy the Amazon one since it says it OEM. Worse come to worse you return it if it's not OEM.

 

Yep, I became aware of this after I threw all that away. Has me worried. I was just wondering if an OEM plastic cap had to be the donor now, or if an aftermarket unit would suffice

 

Obviously you should use an OEM spring and tube because aftermarket tube could have a different number of holes or different size holes which would affect pressure and the spring is critical.

 

This is the exact answer I was looking for!! I hadn’t really thought of the fact that the aftermarket could be machined differently in the sense of the holes. You rock
