2000 Miata MX5
 

Noticed an oil leak the last time I took "Zsa-Zsa" for an oil change .Mechanic said the oil pan was old and the drain plug stripped out, showed me the plug and it did indeed have Aluminum embedded in the threads. Has this happened to anyone else or did they just tighten too hard? If no one else has had this happen then I would be fine with replacing with a used pan. Quoted price to replace pan about $1200 !!!
