is it necessary to change the crush gasket on the oil and transmission drain bolts?

 

it keeps things from dripping.

it's not necessary, but they're only $0.10 each from the dealer.

 

Here's some info from Honda's Owner Link website:

What's a "crush washer" and why is it important to my Honda?

As a Honda owner, the crush washer you should be most concerned with is the one that must be replaced every time you change your motor oil. This crush washer fits between your oil pan and the drain plug. It is a one-time-use washer. Discard the old washer at each oil change and replace with a new one. If you have your oil changed at any service outlet other than a Honda dealer, remind them of the importance to use a new crush washer.


When a new washer is installed and the drain plug is tightened, this washer "crushes" to form a very tight seal, thereby preventing motor oil leaks without overstressing the oil pan threads.


Oil changers who are not aware of its importance may think it's OK to re-use this washer. Since it has already been crushed, it will not collapse further. As a result, the installer may overtighten the drain plug to get a tight fit. This can eventually lead to stripped threads in the oil pan -- a very expensive repair.


This is another example of why your Honda dealer is the easy choice for your service needs. Honda dealers know your Honda best.

 

Yes. And it costs a dime.

 

i never do it, lol

 

well, i went to the local dealer and they did not have any in stock. supposedly it's a different one for my car, he said i could special order it or go out to home depot or lowe and just buy an aluminum washer.
maybe i'll try the other local dealer who charges more than they are supposed to for everything. i paid $5.10 for a quart of ATF-Z1 there and it was $4.25 at the other one.

 

Me neither. I haven't had any problems with either my oil or tranny fluid leaking, both which I have changed without replacing the washer. With all the money I saved not buying washers, I could buy a pack of gum.
