Title: Oil drain plug sealer washer
Post by TheProduct2007 on 10/16/13 at 20:16:30

My the seal washer that goes to the oil plug has gone bad. Anything I can use instead or do I need to go order it online?

I don't know about yours, but I could pull the bolt halfway out and it wouldn't leak. the washer is only there to torque it to.

Yup,.. it don't leak with no washer at all...

Suzuki's tryin' to make $3 per oil change... ;D...

I'm noticing a little bit of leakage with that one on it, I haven't tried it without the washer, it doesn't really look like a washer it looks more like a smaller version of the exhaust gasket

Its a crush gasket,, good for may changes, but a washer should be there to protect the case from the bolt head. Take the old one or the bolt to an injector repair place & buy a copper crush washer,, Itll last a zillion yeerz!
Wont cost 3 bux, eether

Actually, it is a bit different than what most folks would call a run of the mill "crush washer."

My other bikes' drain plugs use crush washers that are made of aluminum and are simple washers - solid disks with holes. The one on my Savage (see my signature block) is a bit different, in that it actually seems to have a seam in it.

I'm guessin' that a generic, properly sized crush washer would work well here, though.....

There are several styles of washers that would work - the key is you want one that is soft like aluminum, or copper. Some of them like VW uses are very soft aluminum and when you first install them they deform slightly and compress and make a great seal - however the next time you used them they will not deform as they have already been compressed. The same thing occurs with the seamed copper washers that are rolled - like what is used on spark plugs.

Even after being used over and over the compression washers will still seal well and can be used again. If you can find the washers with the rubber seal on the inside.....those are realy cool and you can get them at most auto supply stores (Dorman).

Whatever you use - be sure not to overtighten the drain plug. It only needs to be snugged up with one hand on the wrench - don't make it tight!

I fell for the several-bucks-for-a-drain-plug-washer scam for years. All you need to do is to buy a washer made from aluminum or copper or brass or some other soft metal that fits fairly close to the diameter of the drain plug.

You can also make them yourself with sheet metal and scissors.

If the boss is accurately flat, and the drain plug has an accurately flat surface, you don't need a washer at all to keep it from leaking. As has been mentioned here, the washer is there mainly to keep the surfaces from scoring as you put a moderate amount of torque on the drain plug,.. so,... always use a washer.

One time in college when I was pretty much poverty-stricken, the washer on my cb350 got munged up somehow, and I had no way to make or purchase a washer.
-- I just cleaned both surfaces, put a thin layer of silicone seal on one surface, and tightened it with only a few ft-lbs of torque,... not much more than finger tight.
-- That worked fine,.. and for the next oil change I had some thin aluminum (a small piece of scrap from the A&P lab) from which to cut a new washer.

Anyway, this is not a critical issue. Just find some way to get a layer of something between the surfaces of the case and the bolt face.

Theres the biggie,,

Ive got probably 50 my SIL gave me that are teflon coated that fit a Toyota Matrix( No matter now, that no good piece of crap totaled that car),, Id send some, but the hassle over such a cheap answer is not worth it, YOu can go to any parts house or probably even a nut & bolt store & get a coupla washers thatll do the job. Aluminum, copper, brass, even plastic, tho Im not that excited about plastic, but Ive had cars that have them & never had a problem, but they always had wide flats on the oil pan & wide shoulders on the plug. The crush zone on the bike is a little narrow for plastic IMO,.,
