    Question Oil leak from drain plug

    Just a few days ago i changed my oil in my car and it was today when i saw a oil spot on my garage floor. looking unnder the car, i found out that oil is leaking very very slowley from my drain plug. So, i thightened it slightly and thought that should would solve my problem. Well as you can guess im still leaking oil. Anyone know what the problem is??

    or did you replace the drain plug gasket? They aren't reusable.

    the drain plug gaskets aren't reusable?? So when you get your oil changed they put a new gasket on every time?

    Subaru uses a crush washer on the oil drain plug. It is recommended that you change it every time but some people reuse it one or two times. Still other people just get a Fumoto valve and never have to worry about it.

    Im positive they have them. And yes, they need to be replaced every time.

    Happens all the time. Get a handful of crush washers to last you. Make sure to put it on the drain plug right side up. You don't have to do a full oil change. On a completely cold motor, keep the dip stick in and the oil cap on, remove the drain plug slowly until it starts dripping into a pan, then *quickly* pull it off all the way and seal the hole with your thumb. Place a washer on the plug, *quickly* thread the plug back in, wipe up the mess, check that you didn't cross-thread the plug in your haste, tighten the plug, top off the oil (you'll have let some out...), and there you go.

    hi guys just a thought about that oil leak
    you can get rubber/ plastic replacement washers @ Lowes and they are pretty cheap too
    also make sure you have the right torque on the plug about 5-7 foot pound...

    Dunno about with those Lowes washers but the servince manual gives a torque spec of 33 ft-lbs. I'd get the right washer and do it right - it's not something you really want to F with.

    I'm with GV27.

    The works washer is a "double" style crush type, designed to keep you from stripping the sump threads and keep the oil from leaking out regardless. As you tighten, one layer of the washer collapses onto the other -- that's why they're a one shot deal.

    A normal copper washer or even a synthetic one would help sealing, but would not protect the threads. I recommend buying a handful of Subaru washers from the dealer and having them around the house.

    Yup..yup... went to the subes dealership and the parts dude gave me a couple of those washers, (no charge) and as soon as i smashed home i threw that thang on and no leak at all anymore. Although that lowes deal sounds more easy, i think im going to stick with those crush washers and feel more confident when i reach the red... Thanks for all the useful advice.
