OM606 into a '94 Chevy k1500
OM606 into a '94 Chevy k1500
I had a build a few years back that was halted by Colorado emissions.

I sold everything off and moved on but, came across a deal on one of these last week...

the current plan:
- pull engine & sell car
- source a(nother) gm 4x4 nv4500
- source a gm->om60x adapter plate
- standalone ECU with a +200hp tune
- make it work
for now, I'm just looking to get it running. pump work and turbo upgrade can wait.
Hey folks,

The engine has been pulled and the shell sold.

Found some parts and a parts truck this past weekend locally. Picked up an NV4500 and EVERYTHING needed to swap it in. Also picked up a fuel tank in much better shape than mine, and a diesel fuel pickup unit + filler neck. Big score there.

Over the next month, i'm working on some basic maintenance on the om606. glow plugs, checking timing chain component, cleaning (injectors, intake manifold, maybe the prechambers), water pump/tstat replacement, etc. etc. I also home to go through the NV4500 and make sure everything is good there. Once I've got everything sorted there, I'll purchase an adapter, pull/sell the chevy drivetrain, and start working on fitment of the new engine/trans.

i've spent the last couple of months working on the motor.
I took an oil sample, sent it off to blackstone and waited to hear good news before buying a bunch of maintenance parts.
all came back good so:
- valve cover gaskets
- fuel return lines
- entirely new timing chain (more on that later)
- cleaned a bunch of parts (i picked up a cheap parts washer locally)
- painted valve cover for extra horsepowers
- new water pump gasket (already has an aftermarket, metal impeller pump)
- cleaned intake valves (full of EGR produced soot)
- new glow plugs

Timing: this is important. you'll find several "DIY's" on various forums that instruct you to place an m6 bolt in the cam locking position, then turn the crank until it stops. Wherever the crank pulley lands on your timing indicator is how much chain stretch you have.
This is a really great way to think you have 7* of stretch and waste $300 on a new timing chain kit.
Instead, line up the hash marks on the exhaust cam, then check your crank pulley. My janky homemade indicator is about 1* off so, I'm at about 1* of stretch with the new chain. This falls within the "slightly worn sprockets" or "hash marks aren't perfectly lined up" range. I'm fine with that. in all reality though, @ 275k miles, my original chain only had about 1-2* of stretch. that's well within mercedes' 5* tolerance.

I'm in the process of (still) cleaning parts and putting everything together. I hope to pull the 350/4l60e in the coming weeks and sell that off. Once that's done i'll order a trans adapter and get to fitting!
