After changing the oil of my Toyota 4K engine, my Oil Drain Plug seal ring was lost, I installed the plug back then noticed that the oil was leaking. I didn't managed to find any replacement ring or washers instead I used a normal bike interior rubber and shaped it to fit the plug to prevent it from leaking. I wonder if it is okay to use that rubber and if it will met down if I drive for a long trip. No replacements are being sold here at our country, so advising me to buy a new seal ring should not be considered as an answer. I hope you can help me solve this problem. Thanks in advance!
@mn Will a normal aluminum washer will do the trick?
