late 2004 to 2006 LLY engine swap.

[Andersed]

Friend lost a cylinder on his truck, and for a variety of reasons, doesn't want to rebuild it. He bought another engine, thinking that a LLY was a LLY.

His truck is a late 2004, the engine he bough is a 2006 LLY. Is it a drop in replacement?

A 2006 "LLY" is a LBZ for all intents and purposes.

It will not drop in directly to his 2004, but with minor modifications it will. Different number of teeth on the reluctor wheel, and the injector bores are slightly larger (LLY injectors will fit but you might want slightly larger bore o-rings to keep shit out), as well as the water pump being larger.

Change out the reluctor wheel, front cover/water pump, and get some bigger O rings and it should be fine.

Can he use the parts off of his old motor?

Yea just swap the reluctor wheel, (pull balanancer, front cover, oil pump.. then you can get the wheel out), front cover, water pump, and move it all over. While you're at it, keep the cp3 from the old motor because that's different as well (assuming it held good pressure).

What level of completeness is the motor he bought? There are other parts he'll need from his old motor (accessory bracket that holds FICM, FICM, engine wiring harness, etc).

As far as I can tell, the motor is 100%. He bought it off craigslist from some guy in Missouri, met him halfway in Tennessee. It looks like someone yanked the entire motor out of a truck, even the fuel lines are cut instead of disconnected. Even the alternator is still mounted. If it was an old tractor engine, I could tell more, but there might be something that is missing that I don't see simply because I am not familiar at all with diesels made after 1965, since I don't own any. Thank you for your help.

Either way, you're going to need to swap over some of the accessories and bolt ons. On the passenger side, there is an accessory bracket that holds the alternator. That has a bracket that bolts to it, that the FICM bolts to.

Effectively what you're doing is a long block swap, plus what I mentioned before in terms of reluctor wheel, water pump, etc. All the top stuff (intake, accessories, turbos, sensors, wiring, etct) needs to be swapped over from his old motor.

You can also just [very carefully] cut 1 tooth off the reluctor wheel if you dont want to mess around with swapping reluctor wheels.

2001-2005 is 57x tooth
2006+ is 58x tooth.
