A Valve cover dons't have a tightening sequence, you probably mean the head. On my 93 Saturn sl1 the valve cover only had 2 screws with a gasket. To look up what the tightening sequence for the head would be you would have to look in a repair manuel. I could give you what mine is but if its wrong you could risk bending your head sense their not the same cars. Repair manuels you can usually pick up at autozone or checkers auto for a 10-20 bucks. Plus they would be very handy on putting the rest of the car back together if you have your head off.
AnswerYes a valve cover does have a tightinig sequence as well as a tourque spec, especially on a 16v motor with a aluminum cover. why do people answer questions when they don't know the answer is beyond me.The torque specification for the valve cover gasket on a 1993 Toyota Paseo is typically around 7.2 to 8.7 ft-lbs (or 10 to 12 Nm). It's important to follow the proper tightening sequence and to ensure that the bolts are tightened evenly to avoid warping the cover. Always refer to the vehicle's service manual for the most accurate specifications and procedures.

Not sure about the 1989, but 1990-1993 it goes into the valve cover. Look for a hose running to the valve cover and the PCV valve should be what is at the end of it pushed into the valve cover.
