    Leaky Oil Tank.......Any Help

    Has anyone had this problem?????? Here I am 5 days away from a week long riding trip and I noticed this on my quad tonite. HELP PLEASE
    It appears it's leaking from where the washer that's imbedded in the rubber grommet meets up with the drain on the tank.

    Ya, that's a possibility. I haven't taken it off yet to inspect it, but I wiped it off when I first noticed it and came back about 2 hours later. It kinda appears that the oil is oozing up from inside the rubber. I dunno, looks like a late night now.

    That's a really common place for it to crack. If you can get the drain bolt out without busting it completely, remove your oil tank, take it to a professional welder, and have him reinforce it. In the future, use a torque wrench to ensure that you don't over-tighten that plug, or the plug on the side of your engine.

    the updated tanks have a reinforcing plate to help prevent the spout from flexing.

    What is the stock tank made of? I've heard aluminium and I've heard stainless steel. I have no idea. My 17 yr old nephew just started back up his Vo-Tech classes at school. And honestly, that little fart can lay some beautiful welds with a TIG. He just might have a new class project Monday.

    Get it fixed and start replacing the crush washer at every oil change. And if you're a real torque ape then use a torque wrench. After a while, You will learn the right torque and feel when the crush washer gives and the torque wrench will no longer be needed. LOL I bet a crush over a 100 of those washers a week at work

    Anyplace other then your work or Service Honda to the crush washers? What is the actual size of them? I'm sure someone other than Honda makes them
