sorry for the stupid question, but the crush washer that goes on the oil drain plug has a flat side and a sort of rounded side. does anyone know which way it goes on?

flat side facing the oil pan, or flat side facing the drain plug.

thanks in advance for the answer. an infiniti mechanic told me once but i forget now

 

It has a notch in it that goes in the direction of the threads. The flat side screws down against the head of the bolt, and the rounded side crushes up against the pan.

 

i appreciate your answer!

 

If you look at the washer, one end will have a larger diameter vs the other end. The end with the larger diameter faces the head of the screw, while the end with the shorter diameter faces the oil pan.

 

Picked some up at the stealership...
They're using flat copper washers now.

 

what?? no more crush washers??

 

I picked up some filters/washers from my dealer about 2 months ago and they were of the crush variety.

 

I do a lot of g35 oil changes in my area.. does anyone know where we can get the washers in large quantities at either a fair price or for free?? I bought a few a while ago and they charged me $1 per washer...???

what gives???

 

Can you buy these at a Pepboys or Autozone?

 

no, you cannot

 

I bought a bunch from Infiniti-parts.com
