S60 DETROIT OVERHEAD

I pulled my top end down at the second oil change @6000 miles to retorque the head. All of my intake valves were between .002 and zero lash.

I had set them at .010 during overhaul

 

Did the head retorque make a difference? Any movement on the bolts? I’d like to do mine. Small oil seepage at right rear corner. Did you use the new higher specs?

 

Yeah, really surprised me. I torqued to 225, but over several days.

I had so much work going, and I wanted to give myself the best opportunity at longevity, so i torqued the first day. Covered with plastic and retorqued every morning for four days until I ran out of other work and finished the top end.

During the retorque after initial break in all 36 bolts moved. I saw several turn as low as 194 ft lbs

 

Wow!! I forget the value. I know they upped it and supposedly upgraded the bolts themselves. I asked my mechanic beforehand and he knew about it, and used the new higher values. I guess your experience disproves the opinion that Diesels don’t need to be retorqued.
