Honestly... and Auto wrecker will be your best bet. Buy a new gasket from the dealer. Pick-n-Pull is your best option. Just remember the year and motor size. Most wreckers will have a few Corollas... and anything from 1998-2002 should work. Depending on where you live... I've bought hard to find parts off Rock Auto, but the shipping prices are rediculous. It depends if the part is a "Consumable" then buy new. For covers valve, oil pans and stuff like that I'ld go to a wrecker.
