The size of the copper washer on the oil pan plug.

[amron]

Hi, I would like to know the sizes - outer diameter, inner diameter and the thickness of the copper washer that is used on the plug of the oil pan of the 1NR 1.33 lit. petrol engine.

Thanx.

Thanx for the prompt response. I would like to ask if Toyota has changed the washer's material to aluminium? because I remember for sure that when I've changed oil the last time (it was the first oil change, so the washer was the original one) the washer was made of copper.

I never seen cooper washers on Toyota cars, they are all aluminium and the engine oil plugs washers are also sandviched with paper on both sides. Even fake ones work fine but they are softer and crushed at lower torque settings, basically 5Nm less

I've a lot of those cheap eBay ones, they've never leaked (so far) and it was cheaper to buy a job lot from eBay than the original from main dealer.
