what r ur guys thoughts about retourqing the head?? when i first put the motor in 200miles later i lost the head gasket. and i really dont want to loose this one (tired of pulling the head) thank you in advance

 

Torque cold to specs, let sit overnight. Loosen one at a time and retorque with lube. Do all over again a second time. The next day (3rd day since first torque) drive the truck and get it hot and do a hot retorque to specs. Don't ever, ever get on the pedal until the truck is up to operating temp (160 deg +).

 

I torqued mine to Cummins specs. No retorque required.

 

I cleaned up the bolts and lube them and torqued them one at a time to 66/89 ft lbs and then I used a torque wrench with an max torque needle on it and found out after after turning 6 of them to 90° degrees that the torque reading was between 125-130 Ft lbs. so then I torqued them all to 125.
Why I retorqued the head was because the antifreeze was slightly leaking out of the front of the engine. I had just check the valve clearances and found out that where no 1 cyl was right on before- the valves tightend up .002. The bolts seemed loose on that cyl when loosened them so I hope this clears up this seep.
So does 125 ftlbs seems to be the right torque?

 

i also did a little test with that additional 90deg and found it to being around 130 lbs so thats where i put em to being that the bolts around #5 and 6 r difficult to do the degree thing....and taking one bolt out and then retorquing it isnt really making sence to me.

 

i pulled mine out 1 at a time, cleaned them really well, put molly grease on threads and on the head of the bolt where it contacts the head, and torqued to 135 lbs. i hit 50psi every day, and sometimes more when im not paying to much attention, been like this for the last 20k miles, and still on the stock gasket @ 200k miles
