How is this possible? I pulled the passenger side drain plug in the block to drain all the coolant and switch over from DexCool. The crush washer was bonded to the plug, and my attempt to separate them resulted in chipping part of the crush washer (which I'll admit I've never seen happen). So now I need a new plug. I swung by the local Chevy dealer just before they closed and the parts guy spent about 15 minutes puzzling over his computer. He came back with the answer that it is discontinued. Said "the part shows up in the diagram, but there's no number for it, so it's discontinued. You'll probably have to find it on eBay." Huh? Is this possible? There's only like 8 bajillion LS engines out there.
Strangely, I have yet to find an actual part number anywhere in my searches, including forums. I've found a few aftermarket sets, but I don't need all of the other ones, just this one. I know it's M16, fine thread (1.5 I think), brass, 12mm long below the head, and takes an 8mm allen key. I guess I can order a similar drain plug, but it still baffles me that GM would discontinue this part.
