trying to find out what the pattern is for torquing the head is on a 98
and who do you guys use to get rebuild parts from. like head gasket,rod bearing,rings etc....
any help would be great
 
For all your parts Mumau Diesel Is a site vendor and Cummins Dealer. They have great prices and service is top notch. For torque procedures do a search, there is a ton of info on this.

You torque from the middle of the head, and move toward the ends. But get yourself a service manual and follow the pattern.
 
12v i'm assuming?? Strangely enough this was useful info in diesel power

The article said 66 then 89 then 125.. Others will know much better than DP.. I play with CR engines.. so I can just pass on info..not really knowledgeable. Good luck
 
I like taking smaller steps in increments than that. But that's just me... Little more time consuming though.
 
I did 50 - 90 and then whit small(5lb/ft) steps up to 130 lb/ft. After each step I let stand(cool down) for 15...20min. However, some bolts began to stretch out so I had to swapped them out.
 
Its the typical spyder web pattern, and unless you remove each bolt and lubricate, your wasting ur time, btw the cheap arp head studs are rated for 125ft lbs.

What is this "stretching out" that I keep reading about?
 
Perhaps there is another word available for that.
English is not my home language
