LML hole in the block, LMM short block swap?

[57ringo]

I'm looking at a 2012 duramax with a hole in the block. Do I need to find another LML or can I use the short block or long block out of the LMM I have already?

Block yes heads no

Short block can used. However turbo oil drain and feed are a little different than the lmm.

Do the turbo drain and feed need modified......something that can be done neat?

 

[Blackmax123]

I haven't experimented. But could be as simple and just using the drain pipe and oil supply line from an lly,lbz,lmm

 

[Blackmax123]

Correction... the turbo drain is the same on the lml but the turbo oil supply is in a different location. A simple fix looks to be just using the old oil supply tube for the lly, lbz, or lmm. You could plumb the oil supply the same and you would plumb an s300/400 charger

The drain flange at the bell housing is NOT the same on an LML as it is on earlier models. The studs are spaced farther apart on an LML.

Iowa LLY, are you saying LMM short block wont work then?

It’s not plug and play. There are several items different.

Would you elaborate on what all needs to be changed? I have an LMM short block on the engine stand I rebuilt putting in Mahle race cast pictons, balancing & keying and would like to use it but if it's going to be somewhat cobbled up to us it, I'd rather find another LML.

Contact the guy onhere yesterday that has an LML block that was asking the same question about swapping to an LMM block. Maybe y’all can trade. I think his name is kubitza or something

Do any of you know someone that has done this that I could talk to?
