Crush Washer/Gasket Size ID or anyone have a p/n for Mazda?

[Jonesey]

I replaced the gasket crush washer using 14mm nylon gasket and I'm not so sure so I am wondering if anyone knows the part number for Mazda's spec gasket/cruch washer?

I threw out the metal one (after the first oil change) that came with the drain plug - I should have kept it to measure it!

You really don't need to replace these as they are not really "crush" washers; simply aluminum flat washers. Same ones Miata owners use for the life of the car!

That was fast! Thanks!

12.00 to ship 10 washers?! No Thanks....I'll check out another place

Is that right? Does Mazda tell Miata owners to use the same gasket washer over and over?

Of course not, but we do.

As with all vehicles that use a "crush" washer for oil pans, if you torque the drain plug as specified, it will indeed be "crushed" and seat to the irregularities of the metal of the oil pan. Continued use of the same washer would be fine if you could place it exactly in the same clock position every time.

I would question the use of the term "crush" washer for this item. This is simply an aluminum flat washer that conforms to whatever irregularities might exist between the drain plug and the oil pan boss interface. My Nissan Frontier, which I got rid of to get the CX-5, had a true crush-type washer which is copper, screws onto the drain plug and is made in such a way that it actually crushes and flattens out as the plug is torqued down on it. I changed the oil on my CX-5 the other day using the original washer and have had no problems with seepage. That said, I have decided to change it on future oil changes because it is so muuch thinner than the one on my Miata and could be subject to distortion with multiple uses. All the result of Mazda's weight reduction efforts on the SkyActiv platform. It's amazing how much smaller and lighter the drain plug is than typical Mazda plugs!

I bought a couple of filters from the dealer for $7 each and they taped a washer to the box of each for free. They also sold me 10 qts of the Mazda moly oil for $7 each.

Crush washers are common on many cars for oil drain plugs. Yes, you are supposed to replace them. They are normally made of aluminum or (older) copper. They have been around for decades. You don't have to replace them every time. However, after some reuses, and especially if the drain plug is over torqued, the next time it may drip a little. So, if you have one, replace it. I always keep a couple of used ones hanging around. If you need to reuse one, don't worry about it, just look for drips.

Yikes mazdaparts org, only $29 (my only shipping option) for 10 washers. Ever heard of US mail? You put it in an envelope with a first class stamp. I bet the mail man comes to your business every day.

or I bet you could go to a Home Depot and pick up a bunch of 14mm washers for cheap.

Metal drain plug washers are reusable for at least a few times. Dissatisfied with the prices I saw, I bought a pack of 50 soft (soft is the word here) aluminum 14mm washers on Amazon. I read the reviews and got the one's the Honda owners were satisfied with. I ordered the aluminum because I felt the copper ones I previously ordered from Amazon were too hard to give a good seal without really torqueing down the drain plug. Something best avoided.

i got a bag of them from amazon for an acura mdx-same size...14....the cx-5 leaked the first time i changed oil without changing washer...i cranked it down and got it to stop but knew that would hurt the pan sooner or later

I bought a 5 pack of the rubber 14mm Honda type. They last indefinitely.

A torque wrench would do you well instead of cranking down...

Several years ago I bought some generic drain plug washers "compatible with Mazda Part# 9956-41-400" assuming they'd be fine. They looked just like OEM washers. Several weeks after having used one of them when I did and oil change (drain plug torqued to spec), I noticed some seepage at the plug.

I checked the thickness of the remaining unused washers with a micrometer and discovered several of them to be of slightly different thickness at various locations around the circumference. The difference was not enough to be apparent to the naked eye but easily detected with the micrometer.

I don't know if the one that leaked was of uneven thickness before I installed it, but I have my suspicions.

After that experience, I've used only genuine Mazda OEM washers. I've measured them with the micrometer and have found them to all be of equal thickness around the entire circumference. I haven't had any more leaks.

Ever consider Fumoto? Or the other brand. I own both. It's a game changer imo.

Same here.
