Funny, my truck has 300k miles and countless oil changes over 20 years. I've never replaced the washer.

For what they cost (pennies) why risk it...

I used to think the same, but my transmission crush washer failed only after 1 use. Trans oil was leaking at a rate of 3/10 of a quart per month. Luckily I noticed within that month. Just replace it, costs literal cents and the risk is thousands of dollars.

@@2seep could it be that you didn't tighten it enough? If I notice mine having even the slightest drip I retighten it. Problem solved.

I often reuse crush washers. Heat them with a propane torch to red hot to anneal the copper first. Ymmv.

I've been reusing them for 8 years and just flip it over with each oil change. Never had leaks or any other problems.

I reuse them too! If they don't come with the oil filter I just use the old one, the thing I do is, I just rotate it 🤷‍♂️ never had leaks.

I've also reused them. Sometimes 10 times and it never leaked.

Keep up the good work.

My 91 civic had the same crush washer for the life of the car - almost 200k miles before the transmission died. Never any leak from the oil drain plug. Had to replace the oil pan gasket though.

That's impressive!

Do a video with an Audi or VW. their crush washers noticeably get crushed. BTW had an Integra with the same washer and plug for over 200k; no leaks.

@@EndlessMoneyPits My old VW bus uses a round looking copper crush washers. They will literally crush flat against the oil sump.

i aneal them with gas torch never had a leak

My Toyota crush washers are C$3 or US$2 + each! Ain't cheap at all.

That's nuts.

I bought crush washers, and they seem to be solid aluminum. Doesn't seem like there's anything to crush. Does this seem correct?

Aluminum is pretty soft but I'm pretty sure copper is probably softer. I just know you don't want to use aluminum washers on steel parts because they will corrode faster.

Good crush washers are hollow.

You measured across the centre (inner edge) which isn't being crushed

agreed. What is happening when you tighten the drain bolt is you are causing an impression in the crush washer as it is torqued against the drain pan. This impression is what causes the seal. Your micrometer is not measuring this impression because your micrometer is perpendicular to the impression. A better measurement would be a profilometer. In any case, the fact that you see the impression clearly shows using a new crush washer every time is best. You can't count on the alignment between the crush washer and oil pan being the same time and time again either in rotational or lateral distance. The inner diameter of the crush washer is larger than the bolt head so it will be a different spot each time, causing new impressions which can blend into old ones and cause a path for oil leakage, not to mention altering your torque values. Thanks for posting the video. A micrometer is a great tool to have around the house. I use mine all the time.

So just use one if factory did.

They cost $0.25 each.

That looks like a copper gasket, i believe modern cars often use those. Actual crush washers are made of much thinner material and are really crushed when torqued down.

Copper doesn't crush until it's annealed, do your research before you throw content out misleading viewers.

False. It just takes more pressure.
