49 ft. lbs. Start tightening from the center outward in a criss-cross pattern working your way out from center. Set torque wrench at 22 ft-lbs and do all ten in pattern above. Then set at 36 ft-lbs and do all ten. Finally, set the torque wrench at 49 ft-lbs and go slowly. If you feel a stud not locking in as the others did, STOP! You may have a stripped stud. Do not go back to that stud until all the others are OK. Remember! BEFORE THE STUDS GO ON, 1.) Get a tap and tap the holes in the block. Blow the holes out with W-D 40 and then use a can of "air" to blow out the W-D 40. 2.) Get a die for the studs and mount each stud in a vise. Run the die down the threads to clean and reform the valley-peaks. 3.) Add a VERY LIGHT amount of oil to the threads before they go in. This will give accurate torque readings when the studs are installed. The torque values here are for WET threads (not dry as usual) Recheck the studs at the 100 mile mark (as per a tech at the dealer).

Yes, the 1988 and 1989 Honda Prelude has a VSS that is a cable sending unit that connects to the gauge cluster in the dash.
