Fuel line won't connect in back of Cummins engine

I got the head back on and reinstalled all of the six injector fuel lines, but the fuel line on the back of the head doesn't seem to line up with where I think it's supposed to go. Is this normal, or did I do something wrong during reassembly? Has anyone run into this before?

I've got a crosshatch gauge coming in the mail but I got antsy and decided to try out the new toy... also, how are you guys getting such clean "breaks" in the lines of the crosshatch? Mine are like big bows. Thanks everyone, sorry for another honing question

OM617 Turbo Diesel Swap into a 1984 3rd Gen Camaro – Looking for Advice Before I Buy

3 Upvotes

I've been doing a deep dive on this swap for about a week now and I'm trying to learn as much as I can before I pull the trigger on buying the two vehicles.

The plan is to swap a Mercedes OM617 turbo diesel (from a 300SD) into a 3rd gen Camaro. This will eventually become my daily driver, so I'm aiming for reliability first and fuel economy second. I know this won't be a bolt-in swap and I'm expecting to do fabrication work.

I have a couple of questions:

1. Wiring
From what I've researched so far, it seems like the best approach is to leave the Camaro's factory fuse box in place for the body electronics (lights, wipers, heater, etc.) and build a separate engine fuse/relay box for the diesel in the engine bay. The two systems would only be connected by a few signal wires (ignition, start, gauges, reverse lights, etc.).

Is this the right way to do it? If you've done something similar, how did you wire it?

2. Fitment
I know I'll need to fabricate engine mounts and probably a transmission crossmember, but what other fitment issues should I expect? Things like:

  • Oil pan/steering clearance?
  • Firewall clearance?
  • Cooling system?
  • Driveshaft?
  • Exhaust routing?
  • Suspension upgrades because of the engine weight?

I'm trying to make a complete list before I start buying parts.

If you've done an OM617 swap into any vehicle—or a diesel swap into a 3rd gen Camaro—I would really appreciate any advice, lessons learned, or things you wish you'd known before starting.

Thanks in advance!

Other Crankshaft advice.

I'm in the process of rebuilding an A series engine for my 1975 Leyland mini clubman.

The engine was completely seized when I bought the car so I'm rebuilding it. This is my first engine build so I'm learning as I go.

The crankshaft has some crude looking work on it. How should I best proceed? Is the crankshaft usable?

Thank you.

I’m guessing this logo on the BLOCK means it’s never been resurfaced?
