The existing plastic oil drain plug gasket for my stock 49 year old pan was looking pretty ratty and I replaced it with a fiber one. It leaked, and I’d like to check if anyone has found some on Amazon that worked well. Any suggestions? Thanks.
Here are a few shots of the oil plug, the original plastic gasket, and the new fiber gasket. I installed the plug with the fiber gasket but it is leaking with a slow drip. The plug itself seems to be one of those self threading plugs, perhaps meaning someone stripped out a plug previous to this. ( just guessing), or did all Ford oil plugs look like this. The angle of the photo makes the near left gap look larger but a four gaps are equal and travel up the height of four threads. I have some copper gaskets and nylon gaskets coming on Amazon. The local auto store didn’t have anything suitable. I set my torque wrench to 120 lb inches, (10 lb ft), I didn’t take it up to the click, but thought this is already tighter than I’ve ever torqued an oil plug, so I’ll try another gasket before I take the torque any higher.
I carefully drained the fresh oil into a clean container then dropped the oil plug and re-ran it with a Dorman plastic washer with concentric ribs. I then filled the engine with the same oil. It held fine.
