Broke turbo shaft

[NIsaacs]

umm, might not be a good idea for it to hit the highway and catapult into someone's windshield...

I think I would get someone to haul it. I do understand the cost, but...

If it went down the (straight) pipe it's very likely gone already, just kick the resonator with your foot, you would hear it rattle. But like said, it will be gone, there is a lot of flow in that pipe at highway speed.

If you have the all-aluminum intercooler I'd stick to it and clean it out properly. It's a very expensive part and the factory one is something of the best money can buy.
Flush it several times with a decent solvent to get the oil out, that will also was out debris if there is any on the hot side.

Also it is very unlikely that something that is caught inside will reach the engine, it acts like a filter.

Since you got low pressure indications I’d check for problems caused by low oil pressure. The dash wont tell you oil pressure is low until it’s been less than 6 psi for 30 seconds.

You’ll definitely be limping hope, these aren’t good NA motors.

When the compressor wheel on my turbo grenaded there were metal shavings in the inlet to the intercooler but none visible in the outlet or in air horn area once removed for inspection. I replaced the Intercooler with an OEM unit. When I lost my rings and burned up a piston pieces of rings went out the exhaust and cracked the turbine wheel housing but the shaft and compressor wheel remained intact so nothing out the front of the turbo. I upgraded my intercooler during the rebuild so I have that OEM intercooler sitting in my garage here in Las Vegas. Mine is from a 2006 truck so you would have to make sure it fits and if so you are welcome to it. Where are you headed?

I don't recommend driving it, you could still have a runaway. When the shaft fell out, the vacuum on the engine side and the exhaust pressure pushed most of the oil into the intercooler, it is probably full.

Just asking, theoretically.

If the oil supply to the turbo is plugged and the turbo won't make boost, will it run away? I don't think it would make enough vacuum while running to suck enough residual oil out of the intake system to actually run away. Unless I'm wrong, an oil caused runaway is from a constant supply of oil and high boost pressure in the intake.

Just my opinion, I'm doubting it very much, there's doubtfully enough oil in the intercooler to cause a runaway. May be fogging for mosquitoes, but doubt a runaway. I guess I'll find out later today.

Before I go anywhere, filling it full, see just how much it takes, then start n listen. When it dropped, it was at the middle of the oil pressure, normal, and as I pulled over to stop, it dropped quickly and warning came on as I was turning off key. I'll find out later today. As for N/A, I'm hoping it's no worse than my old 6.2 Chevy.

Where'd you work on Apaches? I started 67V/Y n reclassed 67S n then 67R. 23 yrs total. Our since '06.

...but I hear a mouse cough if it comes to my truck, real annoying ability.

That is so funny! I am the same way.. any little slight diff in noise I am crawling around trying to find the cause!

The issue is that the oil pressure gauge is fake. There isn’t an oil pressure transducer on the block, just a 6 psi switch. So as long as you have 6 psi the gauge reads “normal”. Once pressure is lost for 30 seconds you get a low pressure warning.

I’ve been with the Idaho Army Guard for 22 years. Started out in AH-64A’s as a MTP, then onto 64D’s as a MTP/ME. Currently an MTP/ME in 60L/M’s.

Keep us updatet how the progress is and what you are doing, pictures of the bush fix would be great appreciated.

Plug the oil line, pull the boost hose at the intake horn and drive it the few miles with no air cleaner. It's winter and probably very little dirt in the air. Not enough in a couple hundred miles to worry about. Then clean up the intercooler when you get home.

Update, ended up towing. At 7,000 ft elevation in Flagstaff, no turbo to add needed air to stock injector fueling, it was blowing so much white/gray smoke that it covers 2 lanes for a quarter mile. Not having enough air also caused engine to heat up. Flat n level in lower elevation may have been better, but that wasn't the environment. Now it's on to removing turbo, intercooler, drain hose n oil pan. Then full inspection n replace turbo, intercooler, all boost hoses n anything else I find wrong.
Tow charges were free 200 miles on Sunday and $530 for overage. 100 free yesterday and $700 for overages. I should be able to replace turbo, intercooler n boost hoses for about $1,300 and my free labor. Shop in Flagstaff estimated 2k in labor and 5k-7k in parts. So I think I'm ahead, even w the towing.

The feed line plug I used is a "Gates" flat face o-ring part number G60702-0006. It worked perfectly. Generic name is 11/16"x16 flat-face O-ring male plug.

Thanks for all the replies n help.

Edit: for some reason, the forum did not show your final solution post until after I posted. Surprised you found a plug. Good that you ended up towing, less potential damage. Hope everything comes together.

Fitting at the oil filter is the same as the one on the turbo, both are straight thread with an o-ring to seal to what they screw into, then have a recessed o-ring for the special hose ends to attach to. I know of no way to easily plug that oil line

had to look it up

All back together. Oil pan wasn't that bad to pull. I lifted from front eye on engine, front end on stands n tires off so front diff could droop, loosened but did not remove trans to crossmember hardware, then jacked transmission up till hardware stopped it. Pan slid out and back in easy. Had a miss for a few seconds until all the oil n unburned fuel cleared out. About 400 miles on it so far. All seems good.

Well... over 2k miles on it now. Running great. Still no drips either. Hopefully another 270k+ miles out of this turbo.
