Hey gang, I'm rebuilding my 4d55, and it's time to reattach the oil jets to the block. They're basically a banjo fitting, so there are two aluminum crush washers per oil jet. Are these crush washers any different than the ones sold on Ebay and other parts sites that are for oil drain plugs? As long as they're the same size should it matter? Just wondering if there is different tolerances or materials etc for the oil jet banjo fittings vrs an average oil pan drain plug.
