I'd certainly check for leaks after using a "non-crush" type washer. What's wrong with using a crush washer (p/n 11126AA000)? They are certainly cheap enough. Someone here on the Board made a bulk buy and re-sold the excess on the Board. I bought 20 of them; hopefully he does it again.

I think they are .53 or so at the dealer. I buy a pack of 6 often.

 

At Advance they are more than a buck or so a piece. Come in a cute little display box made to hang on a large display black/yellow. I wanna say 3 bucks for 2 crush washers.

 

I keep the copper assortment here. Some cars (like a 2003 Acura that I maintain) there is hardly any room for a crush washer or even a wide copper washer.

 

Some of the Chevy's get a copper washer.

 

FYI that's all you got on the air cooled VW's. And hardly the reason they leak oil (lots of other reasons).

 

In my opinion beats nothing or a steel washer.

Am i the only one who just forever reuses the old ones.....?
definitely not. actually when i see crush washer questions i got :confused: at first, having never done it and never knowing anything about it. let's see....30+ Subaru's i've owned, driven 45,000 miles in one year before - and i've always reused the old ones.

The quick lube places apparently don't put them on either(if they did they'd probably be 5 bucks).

 

Life goes on without them.

 

I'm usually servicing friends/family or cars to sell. Can't rely on oil getting checked, leaks on ground being reported, etc. Folks don't like to see drips. I prefer to minimize them when possible.

They will last several oil changes, if you do not overtighten the plug. I replace mine every 4 to 5 changes. If you do not have one, you will have a seeping leak, or eventually damage the mating surface by compensating by overtightening to stop the leak.

It's probably sufficiently crushed that it's gripping the threads so it doesn't fall off, and the head is smooshed enough that it looks like part of the bolt head.

I reuse the old washer 4 or 5 times.

Then I replace it with a new crush-washer. Not because the old one leaks; it never does.

But more out of a sense of guilt: The mighty Subaru engineers have decreed that the washer should not be reused, and I feel that I ought to comply. So I do, but only every 5th time!

yeah, basically that is about what i do, I never really torque the plugs down that much, so they never really squish out of shape. I learned to not overtigthen them, I probably should put some more foot lbs on, but never had a problem in 20 years. usually one new washer for every 5 or 6 oil filters.....thru experience, and not over tightening, can reusue them a lot.
