I did not get as far as I wanted today. But got exhaust manifold and turbo on with new gaskets for both. So the exhaust side is done. Still cant believe I have had no frozen or brokem bolts. My turbo has not been off the truck in 13 years. 

 

Tomorrow I work on the fuel side then valve train. We will see how far I get.

No, I got them all. After talking with a couple folks I decided to do a hybrid install. The 2 below them are the studs also. Those 2 were pain to get wrench on when I took it off so I figured to match top and bottom. I did remove the rear one after picture and installed the stock bolt so I could mount the heater return back to it.

Not sure why you are surprised :lmao:

 

It's a perfectly fine procedure for a stock powered truck. 

That's certainly not the case you presented before! :nono:  As I stated as you torque from the center out (you need to re-check) the torque PRIOR to the 90* turns, YOU SAID THAT WAS WRONG, YOU said to back off and re-torque, Now you disparage as it's OK for stock engines, I think he has some mods, but not pushing 600hp, SO where does your regime come into play? After a injector upgrade, ECM programing, Quadzilla,at what point does it change?

There was some initial discussion on re-torque vs re-check.. I think that's been cleared up, yet you're still bringing it up...

 

I do prefer to break the torque again, but that's technique. If you're wanting to re-torque you DO have to break torque. I never said you can't install it per the service manual. My very first post on the subject even referred to the service manual...

 

In terms of when to go above stock I would look at the evolution of the task and engines over the years. The 2nd gen didn't have you back off 360° after the initial torque and the boost was in the low 20's. The 3rd gen has you back off the bolt 360° after the first torque, providing a more uniform clamping of the head. The boost on the 3rd gens is in the low 30's. So if the boost is increased to low-mid 30's I would at least use the updated torquing procedure. If the boost is above 40 psi, then I would break the 77 and re-do it. Anything above 45 and I would go to studs. 

 

 

 

Speak of what's wrong... who is the one who said to tap the head for Cummins head bolts with 12x1.5? They are 12x1.75.

I admit when I've made a mistake, as with the tap for the head bolt.  No one's 100% right all the time

How many engines have YOU rebuilt? or is your technique from "big twin diesel" ?

I did check torque since I figure it came from the factory that way and lasted 440k and 17 years. If I ever go up on the power I will just add studs later.

 

It was a bust around here yesterday, rained most of the day and misty for the rest. We will see .

Thats my garage. I laid a plywood floor for the engine hoist. Not bad for this repair expect for the rain but every thing stayed dry. I pulled the tranny twice out there and that was no fun. The 3rd time I took it to a local shop I know and let them put the clutch in. It was in the dead winter and I could not make myself do that one.

2 years ago I did a clutch just near New Years on my truck and that sucked still being the shop floor is still cold. The wood stove cranked up so when you stood up your about fried to death in 80 to 90*F room temp. The raced to get back to where it was cool on the floor.  :rolleyes:

Beautiful but slow day today. Got the fuel lines and injectors installed. Also half the pushrods and rockers. Finish those tomorrow and adjust the valves and she should be alive tomorrow.

So what do those heads weigh?  

 

And are they somewhat "cemented" in place to get them broke free at first?

I would say about 200 lbs. Based on my brother and I lifting it out of the Saturns trunk.

 

Mine seemed a bit stuck on removal, but couple raps with the dead blow and some tension on the hoist and broke loose easily.

Haha... zero, but we're not talking about rebuilding engines are we??

 

As stated, since you know.. words mean things, MY technique. Any more silly questions? 

 

You did make a mistake, but you didn't correct it yet. Then again, maybe the edit button isn't present for everyone, just mods/admin...I'm honestly not sure.

Well start up will be tomorrow. Got the rockers all in, torqued down, and the valves adjusted. Return line on the head gave me fits, but I am done hugging the back of the motor. Was going to start it tonight but a missing spring clamp and plug in the intake stopped me.20190407_195510.jpg.abcebf3d38da64aeb9ca28d36dbc4e16.jpg

Be careful with the hugging...too much of that and you're looking at a sexual harassment suit. :spend:

 

You did a good job...I'm gonna drop my truck off at your house with a 12 pack in the front seat when my head gasket goes.  I'll pick it back up in a week...:thumbup2:

I seen @JAG1 sneaking around looking for something to do, may want to check down the intake pipe.

No advanced payments, or he'll never leave the front seat.
