Fumoto Oil Change Valve

[Big Dawg]

I purchased a Fumoto oil change valve for my new truck and paid $22. 50 for it. It is basically a brass, lever actuated, ball valve that screws into the bottom of your oil pan replacing the standard drain plug. I had used this plug years ago on a Buick I used to own. It always worked well and never had any problems. The model that I purchased for my new truck was "F104". Some people have claimed that holes or slots have to be cut into the threads of the valve in order for all of the oil to drain out. I don't know if they had the same model and/or type of valve I have or not. Anyway, I let all of the oil drain fom the vehicle via the Fumoto valve. I was curious if I took the valve out if more oil would come out as others had said. I took out the valve and no oil came out. I was on level ground with an absolutely stock 2002 H. O. Cummins. I am not disagreeing with anyone, I'm just stating what my experience was. The threaded area of the valve is shorter than the threaded area of the drain plug and perhaps this is why it drains completely. See photo for comparison.

Any chance they changed the design and made the threaded area shorter?

BD. . you have the new version

FJ40 and Willys lover... .



You may be right. The valves are really nice though and I highly recommend them from my previous experience with them. They don't drain as fast as taking out the drain plug but then again if I take out the drain plug, my oil catcher will overflow. It's just one more thing to make the oil change more simple.

Mine has a constant leak. Not real serious, but always wet. I haven't decided what to do about it yet.

I have one of the old ones with the long threads... I did the same test as you, then drilled some holes in the threaded portion to let the last of the oil out.



I love the valve, it makes chaing the oil easy... and I never miss the bucket like I used to...

I drilled the holes in mine. I'm happy with it.

Anybody know the actual length of the threads on the new valve?

 

[Big Dawg]

Reddog1,



I think they have lifetime warranties on them. The dealer I bought mine from said they rarely get them back but did replace them when they did. It might just need a new washer or a little tightening.

The 01 drains don't fit the 02's. the 02's use the same threads as they did back in 93 & prior. Why the switch? I don't know, but I do know that a buddy of mine is geting one for free (the one I took off my 01 before I traded it in) Never had a leak on any of them over the years & 3 different trucks. Sure makes changing the oil lots easier.

What safety mechanism do they have to keep valve from opening by accident. Can something hit it and open it?

Thanks

Anyone know the length of the thread of the old vs. new. I have one that I bought from Geno's about 3 months ago, and have not installed it yet. It is at my parents house right now so I can't measure the thread. I think I might have the newer one.

johnryan,



There is no safety mechanism, specifically. The valve is basically just a ball valve. The lever must be pushed back to clear it's "locking" indentation, then rotated 90 degrees to open.



One owner here drilled a hole in the lever and put a safety wire through it to keep it closed. Not sure that is needed.



My only concern would be hitting it with a big rock going off-road. It sticks down a bit and is brass. I'd put my stock plug back in, or get the one that uses the screw-on hose - which is lower profile, if I was going 4-wheeling much.

FJ... don't know the actual length. . however the old valve is about 1. 5 to 2 times as long as this one shown [on the threaded portion]

 

[Big Dawg]

Cullyguy...



You're right that the '01's and the 02's are different but I cannot tell you why.



Johnryan...



Some people I have heard use a piece of wire or a small plastic tie as added insurance or piece of mind. This might not be a bad idea if you are a serious offroader. Additionally, some have added an extra washer in order to get lever placement facing the rear of the truck as opposed to the front. Mine just naturally ended up facing the rear. The valve I had on my Buick a few years back never had any problem in over 100,000 miles. Of course my Buick didn't see much off road use either. I'm guessing that the valve (no nipple model) protrudes beyond the bottom of the oil pan maybe 1. 0 or 1. 25 inches but that is just a guess. Like the website says... "It takes two distinct movements to open. " However... You never want to forget about Murphy's law...

I got my Fumoto valve from Geno's garage almost 2 years ago, I never drilled it around the threads. I did drill the handle and I use safety wire just as extra insurance. Mine has never leaked a single drop. I change oil at 5000 mile intervals. Started with Delo 400 (dino) and have used Amsoil for the last 20K miles. I don't have a picture of my safety wiring, but would be happy to post one if anyone is interested.

Put one in mine a couple oil changes ago. No leaks. Makes oil changes cleaner and easier. The info that came with it said it would not interfere with draining all the oil. It's good to know it's true. Thanks, Big Dawg.

Thanks. Unfortunately, the girl outside the truck was wantin' some money. Hmmm... . kinda like the girl inside sometimes... :-laf

I posted about drilling the holes in the Fumoto drain plug. Finger Touch Drain Plug with Holes These holes have allowed all of the oil to drain from my oil pan.



On my 99 CTD the oil pan is constructed like this cut-a-way picture:

99 CTD Oil Pan Oil drains out of the baffle below the threads.



The oil pan must be different on the 02's.
