Default My brand new Fumoto valve is leaking

I've had the fumoto valve on my car for about a week now, and noticed it leaks (almost positive) from the opening in which the lever moves around.

I called (whatever the company is called who makes/sells these) and he insisted that this was impossible, because the chamber that the lever is in does not connect with the valve chamber when closed. He said that I must have misdiagnosed where the leak was coming from or overtightened the valve. I read that some people have leakage issues with the fumoto valve and some don't.

Maybe I got a bad one? The guy on the phone said he would send me a new one... but couldn't understand the conditions in which he would do so. (a bit foreign...)

Any pointers? I really don't like the minor convinience during oil changes if the time in between, I'm dripping oil when the engine is warm.

Also, if/when I replace the fumoto valve with the stock oil drain plug, or even a different fumoto valve, how do I not drain most of the oil I just put in with my very very limited budget???? Should I just live with the slow drip? I'm assuming it will have an negative effect on the amount of oil eventually.

Help would be much appreciated.

You will most likely make a mess hoping to keep most oil in the pan while hot swapping to another valve or drain plug. I imagine you put high buck synthetic in. You can use a small amount of thread sealer on a FEW threads to help prevent leaks like permatex # 56750

More then likely, you are the culprit of the leak, but I highly doubt Fumoto has never made a defective product, so who knows. You can overtighting and distort the gasket to cause a leak. You should not use the crush gasket with the Fumoto valve.

take a picture of it leaking and send it to them, it is some thing that would be very hard for some one to install improperly. They will probably send you a new one if it is a manufactures defect and not some thing like being cross threaded. If it was cross threaded it would be evident on the threads when you pull it out.

Fumoto valves are really just a 1/4 turn ball valve that locks in place. There are only 2-3 seals in them to leak. However being in the environment they are in it doesn't take much dirt in the seal are to make them leak.

I would leave it in and just watch the oil level until the next oil change and then put a regular plug back in. using a wrench is not that tuff to remove/install a drain plug.

When I had mine installed I notched the threaded end so that the notch faced the bottom of the pan and spaced it out with an extra gasket to get the best drain. Probably silly on my part, but it made me feel better and more importantly it never leaked. I prefer the old fashioned change though and went back to a plug.
To the OP, I'm not sure what your leak is, but remember that it is notoriously difficult to find the source of a fluid leak especially in turbulent conditions - such as the undercarriage of a moving car. Maybe you can open and close the valve once over a pan just to make sure the lever is seated well, dry it all off, and then watch for a fresh leak?

Hello all,

I have just purchase this hardware and its soon to be installed. The products looks tough!! Holding it in my hand I had many questions and doubts (i tend to be critical) which eventually lead to WHAT IF THIS VALVE MALFUNCTIONS?

The nightmare of the valve giving way somehow and leaving your engine oil for the poor drivers behind then your engine... o poor engine. The valve is distributed world wide so i doubt this to be reality for anyone? But better to be safe than sorry.

I am curious as to find out if anyone can confirm using the valve for many years without issues? Or if anyone has experienced this extravagant nightmare? - hope not

I'll bet it leaking from the pan not the valve, and that the oils i pooling in an area that makes it look like the valve part.

I had the same thing on mine when first installed, I gave it another 1/16 of a turn to tighten it.

No problems since.

Been using mine for... probably 7 years now, no problems at all. The only issue I had was when I put on a skid plate and then plate was touching the valve which caused some marks on the plate, but some washers solved that problem. Other than that, not a drop. Just ordered 2 more for my other cars.

I had the same problem when I installed the aluminum Rally Armor skid plate. I just took a ball peen hammer and put a little "bowl" in the skid plate to clear the fumoto valve.

I don't think I would feel comfortable installing this valve without having some protection around it. Even though it has a "lift and turn" lever, its possible something could hit it, and it would open up.

As far as the leak, I would agree with a lot of other posters, I think its coming from the threaded connection to the oil pan.

I want to run one on my car but I'd probably shear it off. Lowered car + no under panel = exposed valve = bad.

I have the Fumoto oil drain valve and have no problems.

I installed it using a Subaru crush washer and not the fiber one that was supplied.

I got the one with the nipple and so I use a vaccum cap to cover the nipple.

I also installed the Carbing underpanel, but since I have a 2006, I had to shim the rear Carbing bracket to make it work and so the Carbing underpanel is about 1/4" away from the end of the nipple.

It's always possible that the valve could have a leak.

But if you double stacked the washers to "notch" the placement of the lever, then this may be your problem.

Perhaps you should reinstall it using only one washer and see if this makes a difference?

I use a zip tie on mine to make sure the lever will never lift up and turn. I have had it about 2 years and its great!

How did you set that up? Does the zip tie block where the lever moves up out of its little detent?
