I have a 96 Toyota Paseo it has a problem with oil seals

I just change the head gasket do u think that will help or should I just change the motor

Head gasket might not help if the rings are bad.

do u need to take the hole motor apart to check the rings

Do a dry compression test then do a wet compression test to see the difference. If you don't know how, have someone help you.

thanks I will try it and see what happens
