anyone know this #, and also has anyone had to replace it bcuz oof it leaking oil, my mechanic replaced the seal on it and said it was still leaking, ???

 

I doubt it is the cover, itself. Probably one of the seals or the seal from the oil pan to the cover. The water pump seal is especially hard to keep from tearing unless it is put on after the cover is in place and special care is used to protect it during install. You can find threads about that with the search.

1995 front cover (includes round seals) p/n 12552426
