Question about 1990 Nissan 240SX
You can do a search on Google for "240SX owner's forum" and some enthusiast forums will likely show up. They'll probably have illustrated tech procedures posted by members who have done it. It's a VERY involved job. You need to remove the entire timing assembly (timing belt, tensioner, etc) after you tear apart the front of the engine (and since you're taking it off, you should put on new timing parts, so plan for that), and after that's off, the top of the motor (spark wires, fuel rail, etc) has to come off, along with the valve cover, so you can remove the head. You'll need the new head gasket of course, and new head studs/bolts as well, plus a new valve cover gasket and possibly several other gaskets as well. You will also need to find the torque specs for each of those bolts, and the proper tighten/loosen/retighten procedure for the head bolts (which will likely be listed in a tech procedure on one of the forums).
That's it in a nutshell - it's not for the faint of heart by any means.
