so i am getting ready to put my engine back together and i wanted to change the timing cover oil seal, it wont come out! do you guys have any tricks to get it out?

 

ive always been able to tap them out with a socket or pry them out with a screwdriver
can you post a pic?

 

Is the cover still installed? I have always just tapped it out from the back.

 

thanks guys, whoever replaced it last glued it in like a tool :P took 2 people, a screwdriver, and a mallet to get it out. Now i have 2 different replacements, one has a metal lip or flange around it, the other doesnt. heres a pic i found online, both are identical inside, just one has a "lip"
notice this isnt a ford 289 timing cover, so mine has the indentation to fit the lip.
