KA24E Oil Leak

[Hustler]

I just bought the 1990 240sx yesterday. I got it home and realized that There is a major oil leak. There is oil spray all over the belt and under the hood. I am guessing that it is the front main seal. Just curious what other problem(s) it could be. If any one has any idea please let me know. I am also not sure what tools I will need to replace the seal if that is the problem.

Thanks for the help ahead of time.

front main seal.
pulley puller and probably a 23mm or 27mm socket for the main crank pulley. You'll have to double check on that.
