fumoto valve - had to google that one.

FWIW: I've never replaced any of my crush washers.

yes. or amazon.

i specifically ordered the honda brand ones cause they came in a big baggie. but they are all the same for every car. i use them on the motors, transmissions, occasionally differentials that have smaller plugs. Variety of manufacturers too. mazda, honda, etc.

thats not the greatest example as theres cheaper bunches out there.

note: the nissan uses and M12, where the hondas all use an M14. i just make a 14 work on the nissan. same shit with the mazda. close enough.

I should look into those... I typically only change it when I get a new oil drain plug. Never had a problem with leaks or anything of that sort.

Do you go with Aluminum because of the cost difference or are there other reasons?

they crush nicely and they are cheaper than copper. i see no reason to pay for that. the surface area of the aluminum ones tends to be bigger than the copper. the alum also seems to be thicker too. i kinda like that. in my primate brain, i think it takes up more of the "slack" between the surfaces.

I have seen with both copper and aluminum that the plugs leave nice dents (this is good) in the washers meaning they actually CRUSHED the washer and sealed.

i dont understand why people dont replace these. they are LITERALLY cents when changing oil.

I should buy those. As far as I know my Toyota uses the exact same size plug the D21 does.

Alright! Fine. I'll change mine. Shesh. I didn't know.

I don't generally read the part in the service manuals about how to put the plug back in.

toyota uses an M12 from what i recall of my past toyotas. Even if you get the 14 and they are 12, you just align the washer with the outer edge of the bolt flange and its fine. as long as it doesnt look like a ven-diagram you are good. I scumbag the 14's onto M12's on our mazda every time. im 100% meh about doing it.

right? I dont either for this stuff....mostly because i like to assume you & I arent retarded and dont need to be told to put a bolt back in.

i do know people that do it every other or whatever. however for the cost its worth the baggie of em to me. I swear i bought the bag like 6 years ago and its still mostly full.
