start in the middle go side to side and work your way front and back There is no 'sequence'. Hydrolic intake and exhaust valves are adjusted while the engine is warmed up and at idle. The rocker arm stud nut is tightened until the clacking sound associated with that valve is silenced and then add an additional 1/4 turn. If no clacking is observed with a given valve, undo the rocker arm stud nut until clacking is heard. Once clacking is heard, proceed as described above for a valve which was clacking to begin with. Continue this procedure until all valves, exhaust and intake, have been addredded. Job done. If you are dealing with a solid lifer cam, which was not a stock item in 85', again, there is no sequence and all valves adjustments are done while the engine is 'cold'. The gap between the rocker arm and valve (intake or exhaust) will be around .020" +/-. Check with Chevorlet for exact specifications. Turn the engine, using the starter motor, until the rocker arms are loose at a give cylinder and make the approate valve lash adjustment between the rocker arm and the valve. Repeat until all cylinders have been addressed. Job done.

What is the valve cover tightening sequence for a 1993 SL2?
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.
