Turbo install in progress

[zpd307]

soon enough, i will 3 sets of little fingers to help with all my little projects. my oldest, 3 in nov, is finally mastering the use of wrenches and screw drivers. i have to watch out now because he can actually screw things out now. if i was on my home computer i could dig up an old pic of us up in the engine compartment changing oil/cleanng the egr valve in the old psd, when he was about 9 months old. i should put that on my to do list for tomorrow before work.

, lets see how this works.

Well I got it running today. First thing I hauled a truckload of stinking trash to the dump that's been waiting for me to finish the truck.

Lets just say I am very happy with the improved power and the 3 to 4 inch straight pipe sounds amazing. I have plenty of turbo whistle coming out the pipe. It is audible nearly all the time. I just cannot believe how good it sounds so far.

The road I turn on from my street has a light grade to it and before when I would give it moderate throttle I would be @ 50 coming over the top of it. (mind you I am starting from a dead stop about halfway up the hill) Today using much less throttle I was closer to 60 at the top. It is definitely pulling much stronger.

I did a 0-70 acceleration run on my way back and my highest EGT was around 900*. I used to reach 1100 empty doing the same thing.

Now the bad news. My 1 year old IP was heat soaked and wouldn't start the truck just now. I have changed my filter on schedule and used either Diesel Kleen or Lucas in almost every tank since it was installed. I have put around 16,000 miles on this pump. This was an International reman pump.

The good news is now I will have to install my Moose pump. I was hoping to save it for the new motor I am going to build. 6.9, lowered compression yada yada... But it looks like I'll be needing it now.

So all in all I am pleased with the turbo install.

Its always something aint it man?

Well I guess I shouldn't be surprised but the fun is over already. Before I go any further let me just explain that I take 100% full responsibility for this problem and am not blaming anyone but myself.

I rebuilt my turbo back in February. I did it myself and was extremely careful to check, double, triple or more all my measurements and verify everything was in spec prior to assembly. What I couldn't check was the trueness of the turbine shaft accurately. I checked for runout with the turbo assembled and it was nearly imperceptible even with a caliper. Maybe .005 if I remember correctly.

Anyhow, as I was driving to a friends place to pick up my horse trailer and have dinner I heard a sickening noise. It sounded like a zipper at high speed. Shaft wobble in the bushings. I now need a new turbo. After the initial zip noise it turned into a metallic spinning noise. I limped it the 18 miles home but am pretty sure it's now just a core. I don't even want to think what might have gone through the motor but that's a big part of the reason I put the turbo on this motor and not the new one. I had some concerns about my rebuild and wanted to try it on this motor. Turns out they were real concerns after all.

I will be buying a rebuild this time. Lesson learned.

At least everything is installed now so it will be a simple turbo swap.

Actually I'd just send it to a qualified turbo shop. i'm thinking worst case scenario is you need a whole new center section. Will set you back $300-500 depending on where you go. I doubt the motor got hurt. Fordguy100 had a similar problem back around Christmas. It was worth a try I guess.

 

[Dirtleg]

Well I opened up the intake and guess what I found sitting on top of the air cleaner?? The nut that holds the compressor wheel on. I would imagine that if the turbine shaft stopped suddenly it might cause the nut to come off. Ouch!

This was a brand new compressor wheel.

After doing a little more checking it occured to me that everything was dry. Too dry. So I decided to check the oil line. Bone dry.

This is where I ask how to sign up for the ******* awards.

Apparently there was nothng wrong with my turbo rebuild until I ran it without oil for 18 miles. I am really pissed at myself for this. The galley plug I tapped into is apparently not on the pressure side. I even told myself to verify this a few days ago but then it slipped my mind.

So if you have any kind of insults you feel like tossing out now would be the time.

 

[subway]

ooooooooooooooo you learn ALLOT more from mistakes than success. it can be fixed, no need to go into my ******** stories

 

[reklund]

Where did you tap into the oil galley??

 

[Dirtleg]

Where did you tap into the oil galley??

Back of the motor on the drivers side. It is actually in the head. There was oil there when I took the plug out. Apparently it was part the drain.

I thought I had it right but didn't double check with anyone so all I can say is oops.

D'leg,

That suxxx I'm sorry to hear about your troubles. You're a BIG man for posting this so that others following behind you can learn from your mistakes I hope it's not too expensive to repair and you can get back on the road soon. Here's a pic of the oil port location on the left side of the block (behind the exhaust).
Good luck

Thanks for the clarification on the oil location. I will move the oil line prior to doing anything else.

wow man that really sucks.

 

[jimraelee]

keep your chin up, as mentioned, you might get it rebuilt locally for cheap... check it out and make some calls...

 

[mankypro]

Ugh, man you've got me all freaked about my turbo install now....
