White smoke ???

[240hatchsx]

I have a 93 hatch and need help with a few things about the car. First is where is the pcv valve located. next is i bought this car without knowing alot about 240s and i dont have an AIV system in my car and was wondering if not having it would effect my drive ability or thing else also can anyone tell me what would cause my car to blow white colored smoke when started

Thanks for ur help in advance

no aiv, ok. pcv, behind alternator mounted in a box attached to the front cover under the intake manifold. white smoke, coolant in cyl, bad hg. light blue smoke, oil in cyl, bad valve stem seals. search for the FSM here on nico.
