Hello All, I was hoping someone wouldn't mind being a guinea pig for a little tool i mocked up last night.

My Oil filter housing drain plug (Red Arrow) was stuck on at my last oil change and out of fear of cracking the plastic housing in a vice, i just left it on without changing the gasket under it(this time).

With that said, i made a model of a filter wrench with a through hole so in theory you should be able to hold the filter housing steady and crack loose the metal plug.

If someone is bored and has an oil change coming up i would appreciate and feedback on the design so that i works at my next change

When i do find the time to drop the skid plate and fit check the tool i'll update.

Looks like a great solution!

I have a 4th gen, with the “old fashioned” oil filter, so I can’t be your guinea pig.

This exactly why I love being able to do cost effective rapid prototyping! Twenty years ago it would have cost you over a thousand bucks and three weeks of waiting to make that.

Great idea. thankfully, I haven’t run into the issue. regardless, this is a perfect solution for it.

Or you can use the vise grip style oil filter pliers. Just saying.

I change my 4runner's oil every 5000 miles right in my driveway. Definitely don't want that drain bolt locked on so you can't get it off - or you strip something.

The filter should be hand tight and 1/4 turn further.

What you said is true for standard one-piece spin-on filters since the gasket has to be compressed enough to seal the oil in and not overly compressed that the gasket squishes out and leaks.

However, these cartridge filters have to be turned until they bottom out against the mating part... like a dead stop. Hand or wrench doesn't matter, but you turn to fully-bottomed condition vs. turning to the subjective tightness of a spin-on filters. The only reason I am pointing this out is with "hand tight + 1/4 turn" someone could think it's tight enough without it being fully rotated in and it could leak later.

And even though it's a simple concept, every dealer and quick change place will still over-torque these housings and make it almost impossible to take off without damaging or breaking them.

Or you could use an impact wrench, or you could use a strap wrench, or you could use 64.5(?) mm socket, or...

I respect your ingenuity.

That said, you don't have to drop the filter drain bolt. It's an extra step that maybe makes the job like 10% less messy.

I just unscrew the filter housing, leaving the drain bolt in place. Turn the filter housing upside down to let it drain.

I second the impact comment but suggest a butterfly impact.

What @00Sebby said.
And if you have the metal replacement housing it will be even more apparent that you will tighten until it bottoms out and it will not turn any more. The plastic ones will accept a little torque after being fully seated but not the metal ones.

I can almost remove my metal one by hand.
To make sure it stays in place when undoing the oil filter drain I hold the housing in place with big channel lock pliers.

Sometimes I do the @MeefZah method, it’s just a little more messy. But I bet that’s how the dealer oil changers do it, it’s faster.

Mine was stuck too. When I turned to get the nut loose, it loosen the the entire filter. Lol

Yep, that's how my Tech at the dealership does it. They don't mess around with the center plug.

Thats a great idea for a tool. Nice work.

I just put a wrench on the filter drain nut and hit it sharply with my hand and it broke free. If I tried to turn it the whole thing moved. This was from the factory on the first oil change.

Easylife45 I second the impact comment but suggest a butterfly impact.


Why Butterfly?

this is the 5th gen section captnsolo, they dont use canister type spin on filters like a 4th gen.... & the spin on filters are usually 3/4-1 full turn, not 1/4 turn.
