Do I need to purchase a crush washer for a K&N oil filter? I'm planning on attempting my first oil change. I have the oil purchased and still need to get the filter but I saw on at least one oil change tutorial that they said you needed to replace the crush washer. I'm just not sure if the K&N filter comes with one or not.

 

if you get a k&n filter you're set. all you need is the k&n filter, some oil, and 15mins of your time. you're good to go, chief!

 

are u talking about the washer on the drain bolt bc that is a metal washer and u can reuse it for at least the first two times u change the oil.

 

just hit 24k miles on my '01 yesterday and i've never changed the washer you're speaking of, cjr. not to thread jack, but any info on that?

 

LOL, yeah, Honda wants you to change that crush washer on the drain bolt every oil change....lol

 

I dont know about you guys, but i have been replacing the washer every 3k oil change, just for good measure. Don't know if there is any effect though.

 

Thanks for the replies. I guess I won't worry about changing it this time but I do remember reading somewhere that is it supposed to be changed every 3-6k miles.

 

By the way, if you're looking to buy the 12mm crush washer needed don't bother going to a hardware store. I tried 3 different stores and everyone looked at me like I was retarded. No one had ever heard of a crush washer before. If anyone knows anywhere to get them please share...

 

yeah, you really only have to replace the crush washer when it becomes too "dented" up...

the crush deforms slightly when you PROPERLY torque down the drain bolt....after probably about 2-3 times of being torque on, they begin to lose their ability to detent and form a seal...although you can use them long after, the seal MIGHT not be great...although some people keep em for a long while....it's also necessary to aid in preventing from the stripping of the drain bolt...

i bought 5 from my local bike shop, they actually had honda OEM crush washers in stock cost me like $6 or so for 5...keep em in my toolbox....as for asking auto places...NO ONE has heard of them...i got the same dumb-founded look hoopster got at at least 5 different places...just go to a bike shop or order them online...you can get them online off a store that has an online fiche, just know you're gonna spend more on shipping than the washers...lol

 

lol I've been using the same one for the past 26K miles.
