My Official OM617 Toyota Pickup Repower Thread

[JB3]

there definitely seems to be a lot of prii nonsense on the west coast. The smug quotient seems to be a lot higher out there.

Ive never had any problems with Prii drivers, the only one I personally know is very cool, but there are plenty of them around here, its a popular model for sure.

The only ones that really annoy me are the "I am electric" billboard ones which are just stupid since thats inaccurate, and the mindset to putting that vinyl lettering on a gas electric hybrid says something about the owner.

Im thinking about making one for my 240D. After all, it does have an electrical system, so the lettering is just as accurate.

Good point, JB3!

As I said, it's sad, really, that these folks don't know what they don't know. The smugness comes from thinking that they're doing a "good thing for the planet" and you're not but there's no free ride - everything's a trade-off.

By buying hybrids and manufacturers selling more cars they do more development work, and this drives manufacturing costs down. It improves the manufacturing process too. So I thank prius owners for investing in the development on electric cars. I get annoyed when they purport to have bought THE SOLUTION to pollution. No, no you have not, there is a LONG way to go.

Like the build, keep the pictures coming! A friend with a 4runner has been talking to me about a diesel swap so I enjoyed looking through your build.

Got some more done today, the flat bed frame is bolted down. That thing ain't coming off unless I want it off. Pic is a bit fuzzy, light was fading fast.

Injectors were sent off to Greazzer yesterday for rebuild w/ Monark nozzles. He will pop test them before disassembling them, though we're both certain they're all toast.

I crunched the numbers on my conversion a few days ago. At current fuel prices, it's $0.10/mile less expensive to drive with the diesel power plant than it would be with the gas engine. I've got a bit over 5k miles on the conversion so far, and after adding up the cost of the conversion, I have another 25k miles or 2-3 years before break even.

On to the Prius ranting:

I'm glad that people have the option to buy the Prius. I'm sure it's the answer to prayers for some people. It's just not for me, a used TDI VW would serve me much more. Or even a brand new Nissan Versa or similar. The cost difference between a Prius and a Versa would buy a LOT of gasoline.

My favorite thing about the Prius is that it's not a hybrid. It is powered by gasoline, period. Every bit of energy that is used to move that car is supplied by gasoline.

There are Prius models in other countries, and people who have hacked their own Prius here, that have an "EV-only" mode that locks out the gasoline engine. They also have provisions for charging the batteries from an outside charger. If your commute is at low speeds and a short distance away, you can drive on electricity only and recharge at home and you may only rarely need the gasoline engine. THOSE are hybrids.

Heard from Greazzer this afternoon, he pop tested my injectors and they are in various conditions ranging from terrible to nearly-scrap-metal.

Proceeding with full rebuild.

I took video of the engine running before I yanked the injectors, I'll take another one with the rebuilt injectors and hope fully the difference will come through the camera.

With the injectors in that condition, I am amazed that truck started in our semi-recent 6* temperatures with no block heat.

[Stretch]

Good to know the injectors were definitely causing trouble.

[Cadin]

Greazzer certainly helped mine!

[OM617YOTA]

Just a quick update. I got the injectors back from Greazzer and got them installed.

Things learned:

I goofed a bit, apparently I didn't get the mating surfaces for the injector and heat shield 100% clean. A couple injectors are leaking combustion gasses through the threads where they screw into the head, can be seen as bubbles in the fuel that dripped down during the injector bleeding process. Will have to buy more heat shields and redo this.

She runs smoother and more regularly than she ever has before. I was amazed when I cranked her up. My injector nailing from before is gone as well as some vibration while under way. I didn't dare wind her out during my test, but am looking forward to doing so once I get the timing set and the above leaks fixed.

My timing is definitely off. Gray smoke at idle, still significant black smoke when under heavy throttle. Saw a post on here where someone said timing should be set to the END of the fuel pulse out of the injection pump, instead of the beginning. If so, this could be my problem. I had set timing to the beginning of the fuel pulse from the IP. I'm sure timing was significantly changed by my old weak injectors popping at lower pressures and advancing the timing.

Lastly, the flat bed is done. I'll get pics when I get a chance and get them posted.

Thank you again to Greazzer for the amazing work.

Post a link to that nugget of information if you can.

We are mostly concerned with the start of delivery not the end.

Anyway before messing about with the IP timing I'd check the camshaft timing - 2mm lift method etc etc etc

Thank you sir for the advice. I couldn't find the post stating that the end of fuel delivery was the spot to time to. When I replaced the intermediate shaft bushing, I checked timing chain stretch. Everything showed dead perfect. Timing marks on the crank matched the timing marks on the cam. Do I still need to break out the dial indicator?

I called a local MBZ shop to see what they would charge to check and reset the timing. Seven times the cost of the drip timing tool, assuming I buy one instead of grabbing a delivery pipe from the junk yard and making one.

Photos are of the completed flat bed and my fair lady in her grubbies helping me with the injector install. She was particularly helpful getting the glow plugs back in after the delivery pipes had been reconnected and bled. Her hands are much smaller than mine.

A headache rack and tool/storage boxes will be added to the flatbed. Very much a work in progress.

[greazzer]

You're more than welcome ! Glad the car -- I mean truck -- is running better !

Checking the notch with the crankshaft graduation marks isn't a particularly reliable method. If the chain has been in there for any length of time - as in it hasn't been replaced within the last 5 - 10,000 miles it is expected to stretch / elongate.

You are best off using your DTI if you have one and doing the method as described in the FSM - you need to find out your cam code and then do some simple mathematics after measuring the 2mm lift (actually drop into the cylinder) of #1 inlet valve (2nd valve in) at the beginning of the intake stroke. You should find that the chain is slightly elongated - a "perfect" reading should only happen on a new(ish) chain.

Well they need to put bread on the table too!
