Looking forward to watching your build, and seeing what mods you do to get performance. I did a similar OM617 swap into an FJ40 with 85 Toyota running gear a few years ago. The biggest challenge was the oil pan clearance.

Its a big job but it looks like you are off to a good start

Thank Daner , I did a lot of research before I started this project and still , but I have seen a few FJ40 like you did the problem with oil pan is the FJ40 axle is to far forward right where the oil pan is but unlike the pickup the oil pan is clean from the axle the only thing in the way is the steering control arm but that’s an easy fix , i think you can get away by raise the motor little higher but others they cut and shortened the oil pan by one inch .

I did some progress today putting the glow plug harness and relay I tested it it’s all work like it supposed to , reinstalled my IP and Turbo maybe tomorrow I will drop in the motor and mount the transmission.

Nice job on the swap! Are you running your glowplugs to a manual switch or to a factory timer?

Also when are you going to do this swap to my pickup?

 

[Isaac Peter]

Thanks Dude , finish late last night and it’s been about 6weeks now since I started this project , but I’m using the factory Benz factory glow plug relay not manual , also I’m using the 12 volts shut off valve to kill the Engine so everything is controlled by one Key ignition , finalize the engine together in one piece before going in and I will just hook up all the factory lines and harness like factory when it’s done. Finally the motor is in looks pretty cozy in there isn’t it !

Nice work man!! It looks really good in there.

On my 6.9 IDI I still went ahead and put in a manual switch for the glow plugs. I did this just in case the glow plug relay fails OR I'm in cold weather and the 8 seconds the glow plugs are on by the relay aren't enough to get it started.

Thanks , I tested the glow plug several times and it kicks in every time about 8 to 10 sec . This motor is very easy I fired this motor on the ground no problem .

The Mercedes system is temperature dependent. So colder equals longer glow. I carry a spare relay in my car - but on a swap I would probably utilize the factory system and have a manual button for failure or in case of really cold weather.

The Ford's glow plug system is temperature controlled too, but they will never fire for longer then 8-10 seconds. Ford's idea is that they use a block heater to make up for the lack of time the glow plugs are on to make them last longer and prevent the tips from breaking off from being on too long.

I said screw the block heater and just threw in the switch as backup.

I never thought of that but it’s pretty warm in this state , when it comes it’s pretty easy to wire up the glow plug .

 

[Isaac Peter]

This engine it has also has its own block heater but , I said no way I will never used it ..my 1997 land cruiser doesn’t have one but it fires up all the time!

 

[Isaac Peter]

Finally it’s done all the major work , I just put back the wheels and to see how she stand and I was very surprised that after I install the driveshaft I don’t have to redone my driveline , only the front I have to add spacer I have spare that I save few years ago got lucky , I could’ve spend 600dollars for both driveshaft . so my stock leaf spring held up pretty good I’m worried that the weight of om617 will make the front drop but it didn’t looks like still the same height, the oil pan is not even hitting the steering control arm . When you look the lower bumper level you can see just a bit of the oil pan nothing is hitting the speed bump is still 2 inches from the frame and that’s how was it’s hard to believe. Anyway now I have to make a fuel line and put back all the miscellaneous hardware , can’t wait to fires this up but almost there.

 

[Isaac Peter]

Here is how it looks on all four wheels.

 

[Isaac Peter]

I made my custom home made fuel line as you can see the diesel is much larger size than the gasser , I’m going to make a whole new fuel line .. I tap my Toyota factory oil pressure to the turbo feed line and remove the Mercedes oil pressure line then plug the oil pressure hole and screw it back in .also make my oil cooler mount over the valve cover probably I will cut a hole and put a Subaru hood scoop .

 

[Isaac Peter]

I been working so much time and determined to fit my custom 3 inch straight pipe to wave around the frame and clutch and transmission, not look to pretty but it’s clear and it sounds very good , I don’t have the video I don’t know how to upload sorry guys but I start her for the first time and she fires right up , men the upgrade injector is awesome and the Holset turbo is unbelievable I can tell right away the motor has a more than twice the power compared to what it was , hopefully I will be able to test drive it very soon .

 

[Isaac Peter]

I will attached the the rear exhaust pipe later , just to see how it sounds but save me a lot of cash by doing it myself , instead of going to exhaust muffler shop ..

 

[Isaac Peter]

It’s been a while since I posted, been so busy and been sick as well didn’t realize to update the progress or this build, the truck is done sorry didn’t post that much details as of now Been driving the truck and see what the issue so far only one thing just a tiny bit of oil coming out of the turbo exhaust but found out I feed the turbo too much oil so I have to replace the turbo fitting supply line to restrict the oil feed to the turbo and it was good since , anyway the motor is far than I expected lots of power and the torque is unbeatable, the upgrade injector deliver its potential power , the black smoke is awesome to see, l install a 12 volts solenoid cutting off valve so when turn on and off the engine it will shut all at the same time .

 

[Isaac Peter]

The blue bottle is the oil catch breathing from the valve cover ,I also build a rear tire and fuel carrier all 1/4 inch thick steel using a 4x4Labs spindle and latch. my new ARB roof rack and not to forget Turbo decals..

Well, with the Hawaii license plate on your truck, I kind of doubt glow plugs are much of a necessity... and block coolers would be more likely than heaters.

That’s what she said LOL , but I’ve owned three diesel truck before and none of them needed a block heater at all . My 80series Landcruiser never use glow plug she fired everytime in a split second , but the stupid StuttgartOM617 whether cold or extreme hot you still needed a glow plug to start ,In fact maybe I needed an new A/C condenser that’s What I need!

 

[Isaac Peter]

I order a two new 12inch fan with adjustable temperature sensor relay . Its enough to cool this thing during traffic and more than enough space for my new a/c condenser .
