I NEED TO KNOW THE TORQ SPECS FOR THE ENGINE, HEAD BOLTS ETC on a Nissan versa 2007 1.8 engine . Iam replacing a blown head gasket

get a Haynes manual for your vehicle costs about 40 dollars.

if the job was done properly , re-torquing the head bolts is not necessary
what is very necessary however is to clean out the stud holes and threads before refitting the head and applying thread lubricant to the stud threads
the problem is when there is oil or water left in the holes before fitting that muck creates a false torque reading
the setting is reached but the head is still loose so re-torquing the studs will sill cause that hydraulic lock situation and the head will still be loose
also all head studs are not always the same length so a stud will bottom out at tension but again the head will be loose
and lastly, head gaskets have a sealant applied that glues the head to the block on operating temperature and that will now be destroyed by the oil and water
all of this is explained in detail in the workshop mmanual

I frequently use and highly recommend registering for free at www.autozone.com Your registration gives you access to a variety of repair and shop manuals, most giving you detailed repair instructions diagrams and specs.

tighten all bolts to 22 ft-lbs, tighten all bolts to 76 ft-lbs, loosten all bolts completely, tighten all bolts to 22 ft-lbs, tighten all bolts to 76 ft-lbs.

this was pulled from the service manual for a ca18de which is the engine you have in your car.

this is as you are already finding not such an easy job. you will do your self a favor by going to mitchel online and paying a small fee to acees the repair information for everthing you need to know.

Could be a blown Head gasket or cracked head. Should be a drain at the bottom of the radiator I think on the drivers side. You will need to pull the heads off and have them checked Magnifluxed for cracks. If they find none then install new head gaskets and see what happens. I have the torque specs for your head bolts if you need them. Let me know.

1. Sorry.... I did not see the 2.2 in title. Install the cylinder head with a new gasket. Tighten the bolts in sequence as follows: Step 1: 18 ft. lbs. (25 Nm)Step 2: Plus 90 degreesStep 3: Plus 90 degreesStep 4: Plus 90 degrees
   1. Step 1: 18 ft. lbs. (25 Nm)
   2. Step 2: Plus 90 degrees
   3. Step 3: Plus 90 degrees
   4. Step 4: Plus 90 degrees
