Sump plug washer
 

So I picked up an oil filter and bottle of oil today so I can do an oil change before next weeks trackday.

Now I remember a time when oil filters always had a couple of copper washers in the box with it but for some reason they dont anymore.

Would anyone know off the top of their head what size washer you need for your sump plug? I grabbed a box with half inch washers but obviously it would be nice to know if they are somewhere like the right size BEFORE I let all the oil out :D

06 WRX if it makes a difference!

20.2mm id x 26mm od 2mm thick
Subaru supply a purpose made crush washer for the job
Not a copper one but a (single use) pressed metal one which crushes on instalation
You can only get them from Subaru..........

You can, and I do, re-use the old washer a few times before they need replacing - as long as its not squished dead flat it shouldnt leak

Washers with filters? Never seen that, unless you've had european cars with cartridge filters?

I love these sort of car forums, someone always knows EXACTLY the info you need down to .2mm!

Well it would have had a new washer on at its last 'official' service so hopefully I can get away with re-using it.

What happened to the days of just using copper washers that fit over the plug?!? I'm certain the washer I picked up are around 2mm thick and are concave so will squish when its done up....

Eh....Nah in the good old days of 10 years back you always got a couple of sump plug washers in the box with the oil filter.

Hmm been in the auto industry (in parts) for 16 years, sometimes we throw them in as a bonus, but they never come packaged with the spin-on style filters.

Soft Alloy washers or silicone o-rings are used now because of the shit alloy used in sumps these days.

On this I got a magnetic sump plug from ebay for my car. Came with a aluminium washer and it was too hard to crush.
Leaked like a seive and thought I had done a rear main. Did a service on my car a few weeks back and put some thread tape on and no more leaks.

ive havent sold a filter with a washer yet :P

must be rare

Who are you working for bud?

the copper washers, if theyve been flattened bit much you can rejuvenate a bit.

Hang it on a coat hanger and hang in a flame until it just starts to discolour, then dump it in cool water, and it should soften up a bit

i always just asked for the washer or they asked me if i wanted one aswell.

When I go to regents to get a genuine oil filter they usually give me the crush washer for free.

Yeah just get it from the dealer.

When I used to do my own servicing and I was buying parts from the dealer, I used to get them to tape the washer to the lid of the oil filter box so I wouldn't lose it.

Osborne Park subaru don't automatically supply the crush washer, when I've asked they supply it for free generally.

Maybe it was just the place I used to buy stuff from chucked a couple in the boxes without asking....Nevermind.

I get genuine filters from City Subaru and they supply a new crush washer free.

get a Fumoto valve then you don't have to worry about the washer

If you have a subaru sump plug washer already on your sump plug , you can use it again .Its a better option than using a copper washer which can split...

$40!!! Cant go wrong! Cheers for that, think I'll go fetch my credit card...

For a few dollars, buy a sump plug washer from a Subaru dealer - You can't go wrong. Buy 5 or 6 so there's a few spares on hand for future oil changes.

Ditto

Would Coventrys have the washers on hand? I work and live no-where near a Subaru dealership..

I'm doing my oil change today or tomorrow and I've got a Fumoto sump valve/tap replacing the sump plug. This way I just need to undo the valve to drain the oil instead of having to remove the bolt and washer. The valve locks into place so it shouldn't ever accidentally come on done.

I'll post up how it goes...ie: if it leaks and stuff.

[QUOTE=deviant]Would Coventrys have the washers on hand? I work and live no-where near a Subaru dealership..[/QUOTE]Nope ive tried to source them elsewhere - only Subaru has them - if you can find them elsewhere let me know

Yep your right. They only do packets of generic ones in various sizes. I decided to use a copper washer that has exactly the same dimensions as the crush washer...no leaks since friday even with 'exploring' the upper limits of the rev range....

I'm going to order a Fumoto valve tomorrow. I'm going to begin doing intermediate services myself so it will make the job much easier if I can just open a tap and let the oil go.

Ineresting that the last service was done by professionals well liked by members of this forum yet the oil filter appeared to have been tightened by someone with thigh musles for wrists....it was a serious effort to get it off!!

Thank you for the help guys!

Have you checked Ebay for a Fumoto valve ?

I did now...None on Ebay Aus but someone in the US is selling them but it comes out way more expensive than buying one here. They do next day delivery on them here to.

unless someone decides to drop your oil for you.

The Aus Fumoto distributor owns the XT Foz you see on the homepage. There was a group buy not long ago for $29 on Ozfoz
