frajogag: First off, be aware that these bolts are "torque to yield" bolts (streach bolts). What this means is that instead of torqueing the head bolts to a specific torque specification, they are torqued down to a set spec and then tightened by rotating the bolts a certain angle, like 90 degrees. and all of them are turned the same amount.
This means that the shanks of the bolts must be checked to make sure they are not too thin (or the bolt has already stretched beyond limits and is prone to snap if used)
Here is how you check the bolts. Measure the bolt using a micrometer, at the base, or within the first 13mm from the end where it threads in. Then go to about 10mm before the threads end heading toward the top of the bolt. There should not be more than a 0.23mm (.0091 inch) or less difference or the bolt should be discarded.
Torque the bolts down to 98.1Nm ( 72.ft lb)
Looking at the head from the side, so you are looking at the full length from side to side, I will number the head bolts in this fashion.
#1 & 2 are directly in front of you and in the center of the cylinder head crossing it width wise.
#3&4 are to the left of #1&2, / #5&6 are to the right of #1&2
#7&8 are to the left of #3&4 / #9$10 are to the right of #5&6
Now, you have the sequence.
After the initial pull, back off all the bolts in the same sequence and then retorque them to 36 Nm ( 28 ft lb)
Using a torque angle wrench or having the ability to accurately judge turning angles. Rotate (clockwise) to a 75 degree angle. do this to all the bolts using the sequence I had provided.
Rotate the bolts (clockwise) 75 degrees again on all bolts in the same sequence. The proceedure is complete!

Changed head on z24 nissan motor now have not got any compresion in any cylinders


Sounds like the head gasket is not sealed properly. Did you torque the head bolts to the right torque
when you installed them? You need to tighten the bolts in several passes starting from the middle and working your way out. Is that how you did it?

Install the cylinder head with a new gasket. Apply clean engine oil to the bolt threads and seats, then install the bolts with washers (beveled edges up) in the correct position. Note that bolts 4, 5, 12 and 13 measure 5.00 in. (127mm), and are longer than the others. The other bolts are 4.17 in. (106mm) long.

Tighten the bolts in the proper sequence, in the following stages:
Tighten all bolts, in order, to 22 ft. lbs. (29 Nm).
Tighten all bolts, in order, to 43 ft. lbs. (59 Nm).
Loosen all bolts completely.
Tighten all bolts, in order, to 22 ft. lbs. (29 Nm).
Tighten all bolts, in order, to 40-47 ft. lbs. (54-64 Nm). Or, if you have an angle torque wrench available, tighten them an additional 60-65 degrees.


Hope this helps; remember to rate this answer. Good luck.
