the book says to remove the head bolts gradually. In 2 or three increments and a certain order to prevent damage to aluminum head.
the proper torque sequence follows... looking from the driers side...
Passenger side- 10 4 2 5 7
Drivers side - 8 6 1 3 9 ( rear of engine)
I believe the propper torque is listed as 36-46 Ft-lbs
get specs from your local librarys technical isle look up specs and tightening sequence.
This process is for angle heads struds ( original from Mitsu)... First initial torque must be 20Nm in alternate bolts from center to outside. follow above numbers.... 7 3 1 5 10 9 6 2 4 8 Next step is unscrew all bolts in reverse sequence. Next step is torquing again all bolts in initial sequence with 70Nm. Next step is torquing all bolts in same sequence rotating at 90 degrees. Last setp is torquing all bolts in the sequence for more 90 degrees..
The following sequence will be ok for the Honda civic 1.3 and 1.5 16v with engine codes D13B2 and D15B2. 8 6 2 4 109 3 1 5 7 starting at number 1 and following through to number 10 The 1st stage of torquing the head down is as follows.30nm or 22.1 ftlb After doing this on all 10 head bolts, the next stage is as follows. 65nm or 48ftlb If however it is a 1.6i-vt Honda civic i do have sequence and torque settings for engine codes D16Z6 and B16A2 aswell. hope this information is of some help..
it's hard to say how much to tighten the head bolts without torqing them. I would snug them with a ratchet, and then go around the proper sequence with a torque wrench.
It may bolt up but you'll have poor compression with no power, so the answer is no.
Torquing the '87 Cabrio cylinder head is a three-step operation. Using the correct 12-point socket and - most importantly, following the correct tightening sequence - torque the head bolts to 30 ft/lbs. Next, go back over the bolts in the same sequence and snug them to 44 ft/lbs. A final torque sequence requires all head bolts to be tightened an additional 1/2 turn. Also suggest you invest in both the Robert Bentley and Haynes service manuals for your vehicle. All specifications, torque values and, where necessary, the correct sequence of tightening, are provided.
what is the head torque sequence for a 1991 pathfinder
you can put a 20r head on it. they match up and youll get more power
58 ft. lbs. but must be torqued in correct sequence * 8 6 1 3 9 * front of engine * back of engine * 10 4 2 5 7
Sorry, but what is a 22r ?
Normal wear and tear usually. If you have repeated head gasket failure, there is a problem with the surface or the torquing procedure
get a chiltons or haynes manual. they are full of much needed info for doing the job.
