Remove the exhaust pipe, fuel line, injector wiring, valve cover, the cam bearings, timing chain tensioner, distributor, cam sprockets, cams, head bolts, the head, fans belt(s), the harmonic balancer (main fan belt pulley), the oil pan, water pump and timing chain cover ( as one unit is fine), the timing chain and sprockets. Put it back together with the new components in the correct order with the correct positioning of the cams, sprockets and chains (there are two chains in the 1.6L engine). If you don't do it correctly the pistons might hit an open valve and do damage. This is an interference engine. A repair manual is a must!

Here are photos of when I did it last summer to my 95 Sentra 1.6L 200sx. I am doing another now. This one is a 1.6L 96 model but have not taken pictures yet to post. They look the same.

I pull the engine and trans from the car to fix all the oil leaks etc. too while I am at it. The repair manual said it can be done without removing the engine. I have not tried doing this with it still in the car.
