What are the torque specs for a 1993 6.5 diesel in a gmc truck. I need it for the head bolts and the rail above the valve springs

Not too much information on the 2.2 diesel. A service manual is the best idea.

..

Spec. calls for about 110lbxin

8 4 1 5 9

7 3 2 6 10
EXHAUST SIDE

In sequence,
torque the cylinder head bolts. Torque: 30 Nm (22 ft-lbs).
In sequence,
torque all bolts. Torque: 50 Nm (37 ft-lbs)
In sequence, turn each bolt an
additional 90 degrees.

Click here to see how to torque the head bolts on your 2.3 diesel engine.

U R GONNA NEED A FIELER GUADGE AND THE VALVE LASH SPEC REMOVE THE VALVE COVERS AND INSERT THE GUADGE BEWEEN THE ROCKER ARM AND VALVE SPRING AND TORQUE TO SPEC OR TAKE OFF VALVE COVER TAKE TWO PIECES OF CARDBOARD CUT THEM TO LENGTH OF THE HEAD INSERT ON TI THE HEAD SO U DONT SPASH OIL START TRUCK AND TURN EACH ROCKER UNTIL YOUR NOISE GOES AWAY BUT DO NOT OVER TORQUE U WILL KNOW THE ENGINE WILL BOGG DOWN

!st thing is get the revised head gasket (used on 1993 up) for this engine from VW or Felpro, always use new head bolts or a repeat failure will occur. Using the revised head gasket here is the procedure to torque the head down, it is done in stages. PLease go to this site and read the whole procedure.

What is the torque for the crank pulley for 3.1turbo

Buy a gasket kit for the upper end. Remove the valve cover intake and exhaust manifolds. Remove the head bolts. Remove head and clean up block from old gasket material. Take the head to a machinist and make sure that it is not warped. If it is warped either replace the head with a new one or have it machined true. Install new gasket and get torque specs with new head bolts and follow torque sequence using the correct torque specs. Clean exhaust, intake and valve cover of old gaskets. install new gaskets and torque according to specifications.

Cylinder Head Bolt Step1- (25 FT.Lbs) Step2(45 Ft.Lbs) Step3(65Ft,Lbs).....Intake Manifold(35Ft Lbs)....Exhaust Manifold Center (20Ft Lbs) All Others (20 Ftlbs).....Thanks

its a three step process 1st 29ft/lbs 2nd 51ft/lbs 3rd 72.3ft/lbs
