I have short term memory loss. What year and size motor? The 98 2.0L non-turbo show only 2 oil plugs in the block. I would think there should be more. The part number is 4556018 or 4556018AB. I don't have any to look at, but I think they are a pretty small diameter. One of the older 2.2l/2.5l catalogs show it to be 5/8" diameter.
