Like someone else said....trip over a dollar to pick up a dime. Why are you so concerned about the headgasket being replaced? Its not a big deal at all. If doing it right is confusing you then you should just take it to a mechanic to do the work.

On Edit...I see the engine is already out of the truck....just load it into a truck and take it to someone. I can tell by the questions you have that Cummins is new to you and if you phuck it up doing it wrong or not getting it right then there will be a new thread on what happened.

Dude are you serious??? Just yank the head off. Pull your injectors and valve train first and use all new seals and orings. And a NEW head gasket. Cummins charges $86 for a stock one. And I don't think 12v rods work on a 6.7. You need to use billet rods from what I have seen. Also I think you might just wanna take it to someone who has done this before.

i thought 12v valve rods were stronger and will work??

They will.. but if you plan on big hp for a 6.7, you better go billet..

Issue with 12v rods clearing the cam as well...

Depends on the camshaft.

While it may not be the best way, I have seen a machine shop swap a rod from the bottom in a 5.9 so it can be done. He pulled the crank, pulled the piston to bdc, took out the pin, swapped rods and put it back. I Wouldn't want to do it that way but it can be done.

Interesting. Tempting.

You'd still have to remove the front cover to get the crank out. Not sure how much easier that is than removing the head, given that I need to do head studs anyway.

No.... Why would you go thru the trouble of pulling the crank wich is heavier than the head, the block stiffener. Front case cover and rear main cover? Just why?

You can't fix stupid...

What block was that on because i tried that on a 12v and it dosnt work the piston dosnt come down enough to get the pin out

Edit nevermind i see now its in 6.7 section

Sent with a Droid RAZR in one hand and 14,000 volts in the other.

Stupid is easy to fix... you just usually end up going to jail...

I have been worried about this fella for awhile now.

Well most of us that do this for a living and know these engines. Find the easiest and quickest way to do things why would you jump a puddle and dive in a pond makes no sense

This picture is from the underside of a 6.7 block in-frame with the oil pan removed and #1 piston & rod removed from the top side.
