Leaky Fumoto Valve

I recently installed a Fumoto valve and noticed that it leaks -- a few drops overnight. I tightened it down as far as I could without breaking it and used a new drain plug gasket. I believe the leak is coming from the gasket area, not the valve itself, although I'm not certain. A couple of questions:

1. Should I attempt to re-install the valve or go back to using to the drain plug screw?
2. Since the oil is less than 2 weeks old, can I re-use the oil or use new oil?

Thanks.

 

That sucks!
Do something to make it easier on your self and damm!
I’d personally get new oil but leave the filter. I’d also go back to the original drain plug.
Clean area well check that there is only 1 crush washer.

 

Has the oil pan warped at all or been hit??

 

Had a similar issue when I first installed mine, would start to weep a little once the oil got hot. I tightened it down a bit more and havent noticed another leak since. I felt sketched out tightening down by hand "tighter" than I thought I needed to but I guess I don't have a good feel and am too used to relying on a torque wrench? If you're comfortable, try to tighten her down a hair more and you could be in business.

 

Post some pictures.

I’ve had mine for about 5 years now and it’s never leaked. At first I thought it leaked but it was residual from the final oil change I did prior to installing the fumoto valve. Once I wiped that up, I’ve been all good.

 

Nope.

 

I'll try this again in the morning and see what happens.

 

Put a vacuum cleaner on the filler neck. When you pull the plug, the vacuum will keep the oil from pouring out

 

Throw a little Teflon tape on the threads as well as a new gasket

 

If it's leaking from the threads, dab of black FIPG or RTV will do ya

 

Put original drain bolt with new washer for peace of mind

 

Exactly. Make sure it has a washer. Those things suck.

 

Yeah, that's what I plan to do. I checked it again this morning and it's leaking form the nipple. I won't buy a replacement.

 

How long have you had that in there?

I've had my Fumoto in for nearly 2 years - no problems. When I originally installed it I did over torque it because I failed to read instructions but no problems yet knock on wood......

 

How did you tighten it? On the square main body or on the hexagon shaped part? You are actually supposed to tighten on the square body part, NOT the hexagon. Since the hexagon is shaped like a bolt, some people use that to torque it. Just a possibility.

ETA: I just installed one this weekend, guess I should check for leaks...

 

^^^Truth^^^

Common mistake others have made.

 

Have had mine for months now with no leaks and used an OME gasket.

 

I had done the same using the OEM crush gasket instead of the plastic/fiber washer that came with the Fumoto. Where I screwed up during my install was attempting to torque the Fumoto to factory specs (based on the factory steel drain plug) because I didn’t read the damn instructions that stated to torque to 15 ft/lb IIRC for the softer BRASS Fumoto valve. I think I stopped at about 22-25 ft/lb because it didn’t seem right.....

Needless to say I never removed it after that but no leaks to date....so.......

 

That's why I never bought one,to many things to go wrong with them.A plain ole pan bolt has worked for years for vehicles.

 

True but when you’re having to drop an 80lb skid plate every oil change the convenience of the Fumoto is great as long as it is working for you.
