SOURCE: Need torque specs for oil pan gasket

There likely is a spec for oil pan but unless you are a finatic, you really don't need to know what it is. Simple rule: Don't crank down ******* any fastener. If corners near crank ends have larger fasteners, you can tighten them a bit more than on siderails. Before tightening anything, install all bolts finger tight, to ensure that they are not cross threaded. To avoid warping pan, tighten from the center of the pan, working towards both ends, alternating from side to side as you go. When you are finished, go over it again, using the same amount of force on each bolt. As I said, end bolts can if larger in diameter, be tightened more but be careful not to tighten so much that you will either split or push the gasket out the sides.. Anywhere two gasket ends **** together, I recommend using a sensor -safe dab of silicone. An oil pan is not under any mechanical stress or pressure. I have used this method for many years and NEVER had one leak. If you really need #s, small fasteners get about 12-15in lbs, larger ones about 20.

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

How to tightening torque cylinder head


Heads have to be tightened in sequence and at two stages to certain foot/pounds of torque. If your getting this involved in repairing you really need to go to your local parts store and pick up a chilton or haynes manual with the proper torque specs and order.

I need 1992 dodge spirit L4 Head specs.


Get a HAYNES or CHILTON manual. Is has all tghe steps and tightening torque values. The usual tightening sequence is to start at the center bolt, follow with the center one opposite to it, then follow an spiral going out until you reach the last bolt. As usual, you need to do it in three steps, with a decent torque wrench.

What are the torque specs for the main & rod bearing caps on a 2000 chevy s-10 2.2?


The head bolts are toque to yield on these engines, meaning that once they have been torqued to specification, they must be replaced when removed. If it is an OHV engine (solid push rods with and internal camshaft and rockers on the head studs) there is a sequence to tightening the head bolts. First, tighten all bolts in a circular motion, starting from the center and working outwards. I prefer to go in a clockwise rotation, but as long as it is in the correct order, rotation is not important. The long bolts must first be tightened to 22 lb/ft and the short ones to 23 lb/ft. Next, in the same order as before, tighten the long bolts to 43 lb/ft and the short bolts to 46 lb/ft. Finally, in the same order as the previous two steps, torque all the bolts an ADDITIONAL 100 degrees (10 degrees past 1/4 turn). A torque angle meter is required to do this properly and to specification. A routine of mine that is not necessary, but I have found helps prevent warping when torquing the head, is when torquing to final spec of 100 degrees, first tighten 60 degrees on all the bolts in the same order as the first two steps, then an additional 40 degrees all around in the same order.


Tightening order:
8 4 1 5 9
7 3 2 6 10
