Rod swap through the oil pan ?

thats the truth!

Seriously OP if you are going to go through the trouble to remove the engine, pull injectors, and open a valve to TRY removing the pistons out the bottom you are definately in the wrong place. 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.

Just to clarify, if you read the initial post, the engine is already out of the truck.

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.
 
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.

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

You can't get the piston past the crank or block on the bottom.


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.
