i have a motor in my car right now, but i bought it and the kid said something about the crank needing to be taken to a machine shop. but the motor has high milage and dont want to put it trought the abuse, rather get lower milage motor and be safe. so i would have all the accesories to go on the s14 block. also how would i find out whats wrong with the motor i got in now. i kinda want to rebuild it or something. i have decent knowladge of cars but this is my first tear down of a car and trying to build it from ground up. nothing fancy yet just get it all runing then get all the goodies.
and are valve stem seals hard to replace?
