Anyone know the size of this off hand, so i can get it from the hardware store vs dealership?

Thanks,
Will

 

It isn't exactly a washer. It seems to be made of copper and it crushes when you tighten it to make a good seal.

 

Oh, I thought it was a standard sized crush washer...maybe I am wrong. Anyone else have any input?

 

the stealership will probably charge you 5 dollars for it or something.. But its probably worth it to avoid an oil leak. Also, if u buy your filter from the dealer doesnt it come with a new washer?

 

Not sure I just buy a filter and 5qts oil from auto store...but I see your point on the dealership washer/gasket. I think I'll take the advice and buy it from the dealership tomorrow.

 

You can get crush washers at Autozone; someone in our club did.
I am sure whatever your local auto store is, they have them.
If the drain plug of a Ralliart is the same as the evo, then you want size M14.

 

There's nothing special about it, just a normal crush washer. Different dealerships may offer different ones, too. The one closest to me gives me cheap ones for free. Another dealership has different ones but charges $1 for them, which is absurd.

 

If Mitsu wants too much, try a Honda dealer... Same washer... My Mitsu dealer only charges me about $4-5 for a genuine Mitsu filter and usually gives the crush washer with it... Its a M14 Crush Washer... It sould be replaced everytime you change the oil to keep you from overtightening the plug and pulling the threads out of the pan...

 

hmmm. Didn't realize that there was a washer on the drain plug.

 

It is actually a gasket according to mitsubishi. I picked two up today at the dealership, 1.34 a piece. Anyways, I will def be getting them from the auto store next time. Thanks for all your help guys!

Yea, I ran an oil change without one and I could see little spots of oil where it leaked out on the bottom of my pan. There was no damage that I know of and the amount that leaked out was very little, but I would much rather have the 1 dollar crush gasket on there then have some issue or incorrect pressure in my oil system.
