Build Isuzu 4BD1T Lexus LX450 (Land Cruiser) Build

[Wheelingnoob]

Tell me about it.
I called him this morning as well, basically got the sense that he didn't want to touch it because it's out of stock what I want to do.

May call raj here to see what he thinks.

Raj at Fred Holmes basically said $700-2000 depending on the parts it needs. He also said it may go higher if its badly damaged. Was a bit worried at his lack of knowledge about the pump though. So far NW Fuel is winning in my books, still waiting on a call back from Valley Fuel.

I found a used pump on Ebay for $500 but I'm a bit worried if I get it it may need a rebuild too and then I am out a rebuild plus $500. I also do not feel supper happy with the idea of running a unknown used pump if we go on some remote trips. Peace of mind would be had with a fully rebuilt one.

I'm thinking I may still pull the engine on the truck starting in two weekends and then I can sell the engine its got and trans and hopefully off set the cost of the pump rebuild a bit. Down side with that is that money was suppose to offset the swap cost of which it will not now.

I could swear i came across rebuilt pumps for $1kish + core when i was pondering the motor a local guy is trying to sell for $1k with no injection pump, no exhaust manifold let alone turbo, no intake manifold, no alternator/vac pump . . . . i basically decided that he can keep his boat anchor.

Yeah I have come across Oregon Fuel injection $1295 + $500 core. Would rather have it done locally if there are any issues later.

A buddy of mine in Southern Oregon swears by these guys - http://oregonfuelinjection.com/index.php?pid=61

Don't know anything personally, but $1295.00 for a complete overhaul in 4-5 days? Maybe worth a call.

There is a shop in SoCal, Metro Diesel that my buddy who runs Cat says is good, but no personal experience.

Problems try us, but after you get past them, you get the satisfaction of a job well done...and done right!

Thanks Doug

I had just found them and posted as you posted. $1295 does sound good but if I can have is done locally with no shipping or conversion CND to USD then its the way I will go.

I have been in this boat before so know the issues we hit now only make the end result all the more better.

On a good note the engine runs, its not got any funny noises and idles smooth. So that part of things is going very well. I did find that I have a rear main seal leak as I was worried about the crank is worn to much on the sealing surface to be effective. So I am ordering the Isuzu repair sleeve and the 6BD1T seal to repair it for good.

Just got a call from the final local reputable injection shop and they said they have not worked on a pump like that in 15 years and had no idea where to begin with a quote. So it looks like if I go local it will be NW fuel injection.

I'm going to call Oregon Fuel injection just to see what all they do and what sort of warranty there is on the work.

Just starting to scope out potential vendors i know what you mean by the issue of "reputable"

salt lake city is home to an "Industrial Diesel Service" co.

Their website only mentions consumer diesels, has bright blaring ads about the latest gizmos, and advertises free hoodies and hats and whatnot with different types of service.

Industrial indeed.

Yeah one reason I feel ok spending the extra to get NW to do mine is I use to work next door to them, they have been around for a very long time and there work seems good. They had rebuilt a few EFI fuel injectors in the past for me. Another thing I like is while I worked in that building they where always servicing cab over diesel trucks like the one my engine was from.

None of the other places I have called where very confidence inspiring. I also do not want to save a buck and then have to constantly badger the place to get the job done. If I can get the pump done I am 2-3 weeks form starting the swap.

can you post a picture of the data tag on the pump and i will get you a guesstimate price to rebuild it. It will mean you will have to ship it to Alabama, but we are the largest fuel shop in Alabama by far(city diesel).

Any chance that this is really a pump timing issue?

Thanks for the offer, if I was clouser I would but shipping would be a killer.

I cant see the pump timing being so far off it does that. The timing marks are dead on. I tried to spill time it tonight and aling with making a huge mess it seemed to be about 10-13deg where it should be. I got the pump off in 45min tonight and its going into NW Fuel Injection in the morning. Going to have them test it forst and see if they see any issues. Then we will go from there.

I feel good using them, I know quite a fewwho have used them and they are all happy.

I have to tell you, that first pic looks like a work of art. You should somehow figure out how to get that under a glass coffee table for a bit.

Hello Wheelingnoob,
I am in total and complete agreement. I am jealous as well, as i am not a mechanic, yet love things mechanical. I have a naked '80 Goldwing, and love the engine architecture, particularly with the intake pipes paralleled by the exhaust headers; your gorgeous engine is lovely.
Nice going, admire your patience and determination, and don't give up.
Cheers, 61Mk+

alright, best of luck!

As Red Greene would say, We're all pullin' for ya.

 

[Wheelingnoob]

So I dropped off the pump today, they took a quick look at it wile I was there and said it looked to be in good shape. He asked too about timing, when I checked it last night I thought I know the procedure but after reading the manual again today I think I did it wrong. I'm going to call and see if I can get some advice on the trying to set the timing again first.

They can bench test the pump but at a cost of 4 hours labour.

This may not be what your pocketbook wants to hear, but rebuild it. Once it's rebuilt by someone reputable, you'll know for sure that it's good for years and miles to come. Captial investment, which this is, now will save you heartache, time, and money down the road. Removing it once it's mounted in the truck is going to be a huge PITA. You're doing everything else with great detail and thought, and a major component like this should get the same treatment. Just my two cents.

 

[69rambler]

Your description sounds like timing to me. If you can't isolate the problem to one cylinder I would not expect the problem to be pump/injector related given the history you've stated.

Most diesels will start and run with injection timing far from where it should be. They will stink like unburned fuel, smoke odd colors and run terrible.

Does Isuzu give specs for injection timing in plunger lift @ crank position? That's always easy to check with an indicator if they do.

Yes that is what my gut is telling me to do as well. Its my wallet at this point that is telling me otherwise. As with all swaps its started to snowball and I need to take a very critical look at every expense from here on out.

Well that's the thing, I did not try running it again and just pulled it off out of frustration.

Its starts and idles fine as far as I could tell, no smoke or strange colours other than normal diesel smell.

I think they do, all there manual talks about is setting timing via the spill method witch I thought I had done last night but after a closer read I had not removed the delivery valve.

The gear's where all dead on for the cam, crank and injection pump last night when checked and the pump is lined up with the timing index mark from the pump to the mount. I cant see all those lining up and pump being so far off that it does this above idle.

I think I'm just getting a little fried from all this as well as stresses at work so I am making some dumb decisions.

 

[gerg]

I dont think its a fluke that the engine behaved that way before and after you reuilt it. The only thing you havent changed was the pump. It kind of points a big finger just at it.

Yeah, that's why I was quick to pull it off. Having said that the timing was the same pre and post rebuild. I talked with NW fuel and he said the symptoms I am describing could be injection timing to retarded. So I'm picking it up tomorrow morning and will refit it. I of course badly bent the fuel feed line from filter to pump so need to try and straiten it with out breaking the line. Then order a new one to replace it before it gets driven.

 

[Dazed]

What about getting the pump rebuilt, that part is checked off the list. Then redo the timing from total scratch, by pulling the timing cover and redoing all of the gears and lining up the letters? May take less time and you know it's right.

I gave up on keeping track of the snowball and jsut decided to do it right. I plan on driving my truck for a very very long time.
