Oil Drain Valve (UPDATE)

[Jay2004]

I bought and tested this drain valve today at the dealership. It's a no go! My service guy tells me it's super tight to put in. The size is right, but the threading is not really is off a little and if you force it, it can strip it completely. Don't buy yet! I'll still look around for another one. I'll try reaching out to fumoto to ask them if this right or not.

Got mine today! I will let you know when the car gets back fro the shop and change oil.

Did you get around to installing the valve ?

It couldn't be done without risking stripping the thread.

@Jay2004 , was this the F-139 model (M12x1.5mm) or the F-133 (M12x1.25mm)?

 

[Jay2004]

It was the F-133 model.

as stated in an earlier post, the correct oil pan thread is M12 x 1.5 (F139 model).

The one you bought is the wrong thread pitch. Mycarworx.com has the wrong info

Thanks for the heads up. I'll buy and test that one out.

Wouldn't you just get a BMW one that fits BMW B58 models?

I attempted to install the F-139 drain valve yesterday and it looked like it would be a good length for fitment above the splash shield, but on the last turn or two it began touching the pans protective lip around the plug. I tried with the supplied washer and then an OEM crush washer and neither provided enough clearance. I sent an email to the Fumoto support describing the issue and asking for any recommendations.
I am extra cautious when it comes to brake fluid lines and anywhere oil needs to be sealed in. The only options I see possible are 1. notching the valve where it touches (but it might compromise the structure of the expanding and contracting valve due to heat cycles) 2. grinding down the lip (personally never an option) 3. double up washers to make up the gap (probably can work but prefer something else) 4. make a 3 or 4mm threaded spacer of the same metal, slightly larger in diameter than the crush washer, and loctite onto the valve and use an oem crush washer. The only option of those Id be remotely willing to do would be 4, but even then...still would lean towards not using it.
We'll see what Fumoto says and if they have any proven methods. If their initial recommendation is something like 4 or they have an adapter, I will try it, but with 100% skepticism leaving the splash shield drain cover off and inspecting for leaks often for the first few weeks.

this is looking like a better option based on how it is shaped

I'm a big fan of Fumoto drain valves. I have them on most of my cars. (3 to be exact) With that said, I chose not to pursue putting a Fumoto on the Supra because the plug points straight down. Adding the height of the valve at that orientation could potentially be an danger point if you run over something substantial or case the vehicle over a bump.

I'm using this and currently have no issues.

Also, there is a cover underneath the plug, so I don't see an immediate danger with Fumoto or this design. If you're unlucky that a stone gets in there and knocks it down, well, then you're unlucky ?

I was of the same mindset when I saw how low the drain pointed down. My initial reaction was thinking it's basically like a big bolt an unexpected speed bump is gonna hammer into my pan. Looking at the orientation and location in relation to the wheels, the suspension would have to travel well beyond the bumpstop to allow the pan to contact the ground. If the object was big enough to be able to hit it, but not let the wheels lift the car up to roll over it, it would have to pass through a bumper and quite a few things before it hit the pan at its height. I would categorize a situation like that as the same kind of freak occurrence that can damage the pan regardless of what drain it's using. But I get it. It's not THAT big of a convenience to trade piece of mind for.

How long have to had the valve type installed on the Supra?

In my 2013 FR-S, I was on the freeway and I unavoidably drove over a chunk of concrete (imagine Chipotle burrito sized). The chunk was tumbling and went straight down the center underneath my car. It surprisingly didn't leave one scratch on the front bumper lip or engine skid plate, but completely hammered the living $hit out of my exhaust and floor panels. It literally looked like someone took 3 swings with a sledge hammer to the bottom of my car.

I agree, highly unlikely something would damage that particular point on the underbody, but stuff happens.
