ive read all the DIY articles on changing your own oil. but no body seems to mention where to get the new washer for the drain plug. i'd like to know where to get it and what size? and to what torque to tighten it back up to.

 

Its called a crush washer. You can pick one up at any auto parts store. Its not a necesary part so if you don't have one don't freak. It mainly forms a tighter seal between the bolt and the oilpan.

 

Considering it's a $0.60 part, and oil pressure goes above 120psi, I would definitely invest in getting a few. You can order them from performance nissan and they will get there in a couple days. Get like a dozen.

 

Well --That 120 PSI isnt in the pan !!!!!!! Good Lord---But true --Iv never replaced mine but it would be a good idea to have a few on hand ---Like the Plastic fender well.front bumper, and other assorted connecting clips. Now those I do keep around.----The gremlins keep stealing or bustin them !!!!

 

i get a free one everytime i purchase a filter at my dealership...yea get a bunch they are cheap

 

So they are crush gaskets? What I always am getting from autozone are rubber type ones. Thats what the computer showed for the car.

 

Why not use a crush washer like Nissan designed for the car?

 

Well --I dont know --Iv got 50,000 miles and havent changed one yet on mine with Zero Leakage. And of the 100s and 100s of oil changes Iv done Iv maybe had to replace a dozen on other vehicles ----

BUT ---the best are the copper ones that are readily available and the aluminum one work fine too

And ya ^^^^^^^ if ur worried just get what Nissan uses----I never paid attention to what they use

 

It isn't? I thought that's the oil pressure sensor right there next to the oil pan...

I typically buy the assorted pkg at the auto parts store, never know when or what size to use on different applications.

 

The sensor IS right there, but the sensor/filter/FI feed/ whatever the case may be is plumbed into the upstream side of the oil pump (pressure side) Where as the sump assy.(oil Pan) is on the downstream side of the pump.
Notherwords the only pressure there (in the pan )is the force of gravity.

The oil is picked up from the oil pan by the sump then pressurized and fed to the lower main brgs, lower connecting rod brgs,generally splashed or sprayed to the upper piston pins/cyl.walls. Via another route lubing the cam brgs. Then simply dripping down to the pan again to continue the cycle. Differant engines use differant routes but none have pressure in the pan of any amount.

 

Thanks!

 

do NOT refer to them as "crush" washers. I went to performance nissan and said "I need the washers for the oil drain plug", to which i was told "oh you need the crush washers". I was like "er..yea i guess"... went home & realized an O-ring & a crush washer are not the same.
The crush washer is smaller than the O-Ring, meaning it will not fit over the bolt that screws into the Drain plug.
The crush washer /aka/ oil filter washer is a perfect fit for the oil drain plug bolt, but thats it.

You need O-Rings for the drain plugs.. I will take a pic of a crush washer when i get home & post it tomorrow...

 

Isn't this thread about the oil drain plug?

Attached is a pic of the copper oil drain plug crush washer.
