SOURCE: tightening head

New Headbolts are recommended

Long bolts are torqued to 46'lbs + 90 degrees.

Short bolts are torqued 43'lbs + 90 degrees.

Start in the center, and work to the edges, torquing the bolts in two stages.

Rockers are torqued to 22'lbs.

SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

SOURCE: how tight to tighten valve cover

I highly recommend you buy a Hanes/Chilton manual for your make and model of car. The manual will tell you inch pounds and torque sequence for tightening the vale cover back on. Usually the sequence works from the center and works it way to the outside bolts. Please rate this reply if you found this helpful.

How do you Replace Head Gasket for 2002 Nissan Sentra GXE ?


Big difference between valve cover gasket and head gasket. To replace head gasket, you must dissamble top end of engine and send the head out to be resurfaced and then install new head gasket. If it is a leaking valve cover it is much easier. Simply dissasemble and then clean valve cover and top of head from all debris and remove all old gasket material. Tighten back down in sequence and do not over tighten. these small bolts can be overtightened easily so go in sequence just like when you tighten lug nuts by skipping one as you go around. 10mm bolts require about 10 pounds or less torque.

99 camry 2.2 l engine valve cover gasket leaking in the backside, replaced gasket and its still dripping on the manifuld. Driving me crazy. Whasts my solution? anyone ?


There is a proper tightening sequence for the valve cover bolts. I've found it extremely helpful to put a bead of RTV on the valve cover gasket to help ensure a solid seal. I've had problems with the aluminum threads in the head stripping out before reaching torque spec. You can use longer bolts in some of the holes on the head if you have stripping problems.

You should also wait 12 hours before starting the car, as you want the seal to take.

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Properly relieve the fuel system pressure.
  3. Drain the cooling system.
  4. Remove or disconnect the following:
    NOTE Place shop rags in the openings to prevent debris from entering the engine.
    Negative battery cable Accessory drive belts Crankshaft damper Intake plenum, lower intake manifold and exhaust manifold Valve and timing chain covers Coolant connections for the cylinder heads
  5. Rotate the crankshaft until the crankshaft timing mark aligns with the timing mark on the oil pump.

  1. Thoroughly clean and dry the mating surfaces of the head and block. Check the cylinder head for cracks, damage or engine coolant leakage. Remove scale, sealing compound and carbon. Clean the oil passages thoroughly.
  2. Place a new head gasket on the cylinder block over the locating dowels.
  3. Inspect the cylinder head bolts for necking (stretching) by holding a straightedge against the threads of each bolt. If all of the threads are not contacting the straightedge, the bolt should be replaced. New head bolts are recommended.
    WARNING Due to the cylinder head bolt torque method used, it is imperative that the bolt threads be inspected for necking (stretching) prior to installation. If the threads are necked down, the bolt should be replaced. Failure to do so may result in parts failure or damage.
  4. Lubricate the bolt threads with clean engine oil, then install them.
  5. Torque the head bolts in the sequence shown in the illustration, utilizing the following steps and tightening values:
    1. Step 1: bolts 1 through 8: 35 ft. lbs. (48 Nm).

Need 1990 nissan sentra torque settings and valve clearence


heinrichkemp: The engine in your car is a GA16i
I venture you are asking about the head bolts when you refer to torque settings. The head bolts used on this motor are torque to yield (streach bolts) If you are reusing them, you need to check them to insure they are not stretched beyond limits.
The way you measure the bolt is with a micrometer.
Measuring close to the end where the bolt starts to thread in, about 10-12 threads up, take a reading. Now, go to the other end of the bolt where the threads end and measure about 10 threads in.
There should not be more than a .009 inch difference (.228mm). If there is, discard the bold and get a new one.

You must use a sequence to tighten the bolts, below is the sequence.
11
13 9 3 1 6 8

14 7 5 2 4 10
12 15

torque 11,12,13,14 & 15 to 8.3 Nm (6.1 ft lbs)
Torque the main head bolts by the numbered sequence to
29Nm (22 ft lbs) first pull
64Nm (47 ft lbs) second pull
Loosten all the bolts completely
Tighten the to 29Nm (22 ft lbs) first pull
Tighten bolt # 1 clockwise 85 degrees
Tighten bolts #2- 10 65 degrees
Nissan noted that if you do not have a torque angel meter, you can use a regular torque wrench and torque all the bolts to 69Nm (51 ft lbs)
The valves on this engine have hydraulic lifters, consequently require no adjustment.
