Low Turbo Boost ? Common Causes Explained. Watch Before Buying A New One.
#garrett
#duramax
#cummins
In this video I have a truck with a low turbo boost complaint. I give a quick description on how turbos work, what can cause them to not build enough boost, how and what to check for leaks.
A lot of people would assume the turbo charger needs replacing of you have low boost. That might not be the case. You can have any number of problems that can affect the turbo. Basic engine issues, Restricted exhaust or intakes, loose hose clamps, leaking pipes hoses, intercoolers, computer issues or even a bad egr valve.
There might not be anything wrong with the turbo. I hope the tips I shared in this video help people save the cost of replacing a turbo that may not have anything wrong with it.

@Re-engineer_everything Жыл бұрын

I don’t know if you reply to this video anymore but I have a 2003 LB7 stock/S475. When I try to boost test it I get a bubbling or gurgling sound in the pipe that crosses from the S475 to the stock/Valley turbo. Could that be blow by? Where the pressure is going? It is a new built engine capable of being a 700HP daily driver. It has about 1500 miles on it.

Thanks for the vid man! Idk yet what my prob is but some things to check for now. LBZ Duramax, seems the vanes stick occasionally on hard acceleration? Sometimes when pulling out of my subdivision, sometimes when mashing the pedal getting on an open highway. My edge might show 8lbs boost while truck is hesitating, maintaining the same speed, then Bam 28lbs take off! Only happens occasionally though? 👍🏻🛎🛎

@@shanersmechaniclife3164 "People are too quick to throw new turbos at systems with boost leaks or other issues." You could not be more correct. I spent so long replacing boost hoses in my land rover for a turbo underboost - P0299 DTC. After I did that and it didn't fix the issue, thought it could be intercooler or exhaust gasket on the turbo failure or potentially a clogged DPF that's adding too much back pressure to the exhaust manifold. Took it to the mechanics who almost immediately diagnosed it as a failed turbo. I was so sick of having this issue (5 months now) and just agreed to the works. Guess what? Didn't fix anything. I've just bought a smoke machine to see if I can find boost leaks this way. I've sworn off taking my car to a mechanics anymore unless I've diagnosed it and can't fix it myself. Most mechanics nowadays just read DTC codes and have very little diagnostic skills/experience

The easiest was is take an airline and fit it in the boost pipe just after air filter. Fill up and see if air leaks out. Then if using scan tool go live data and search boost. All boost pids will appear. Look at boost sensor and note that figure then look at commanded. Note that figure. Accelerate and the boost should rise and figure be same as commanded. If not disconnect actuator arm and slightly wedge gas pedal. Look at scan tool as you put the actuator arm in turbo. Does boost increase. Yes then actuator or wiring or computer fault. No then turbo crap. Thats my understanding

@brianbabb9127 Жыл бұрын

Maybe if your boost is too low for what you need you can increase the air and fuel mixture on your boost sensor by adding a potential meter to send message to the computer and it doesn't overheads any diodes or resistors works very good

@brianbabb9127 Жыл бұрын

Overheating

@balam8743 4 ай бұрын

I want to add that the valves/seals and pistion rings can be the source of low or no boost problems as well. If you block off before the intake manifold and put pressure after the turbo you can see if that section is leaking or not and elimate that section off. Next I would pressure test the crankcase to make sure it's not the piston rings or valve/seals.

Thanks for the help, I have an ISC 8.3 1999 In my Monico Rv. Just changed cracked exhaust manifold. Air side of turbo spins freely, no boost, can hear turbo at all when reving engine slightly, 12-1300 rpm. I haven't check the actuator yet, but it could also be EGR valve?

@shanersmechaniclife3164 Жыл бұрын

If your egr is stuck closed your combustion chamber Temps will be high which can cause exhaust manifold to be hotter and more prone to cracking. If your egr is stuck open exhaust can be going into intake when it's not supposed to causing low power and stalling. Exhaust that should be spinning the turbo is going through intake. Boost can also be going into exhaust through a stuck open egr causing low or no boost. Definitely something worth looking into. Let me know what the problem is once you find it.

The intake & exhaust valves are still all intacked with the old engine and they dont look that damaged, the shop said the valve stems where just bent and didn't break off. When they drained the oil there were metal flakes in the old engine oil. Could this have damaged my turbo on the turbine exhaust side?

After installing the new one and getting It calibrated with my computer ,When I start the truck it’s surging ? I replaced batteries on the truck a day prior just cuhz they looked like shit and we live in Arizona . Before I start the truck it says low voltage ? And when I start it it goes up to 15 if I hit the throttle a little bit it goes up even higher but then the engine starts running like shit and I turn it off . I’m not getting no codes related The turbo anymore those all Cleared out . I changed the alternator after seems like a reasonable thing to change . But the new one doing the same shit ? 2 faults I’m Getting Sam chassis short lo ? And then 530602 fmi4 ? You think it’s something electrical? Or you think it may have a leak like you was talking about ?

Check for corroded wiring going to inline fuses. Also look at battery disconnect switch. Those connections like to loosen off and arc out. If your battery voltage is good but the ecm reads low... I'd look closely at that. Let me know how it works out for you. Good luck, keep me posted. Thanks for watching.

I have a P0299 Turbo/Supercharger underboost fault on my 2005 Range Rover Sport 2.7TDV6. The car seems to loose power and stall when i reach a speed of 50MPH. No check engine light/eml light on the dashboard. I hope it's not the Turbo.

@shanersmechaniclife3164 11 ай бұрын

Clogged exhaust could be the problem. Exhaust flow is what spins the turbo. I would do a back pressure test to verify. Could also be a clogging intercooler. Hope it works out for you. Let me know what you find. Thanks for watching and commenting.

@shanersmechaniclife3164 no boost leak after we plate the gas recirculation tube it blew soot for a while then cleared up so I'm pretty sure the exhaust was clogged, I'm going Going to take the plate off and see if the spn 102 code comes back. I bought the truck deleted. They didn't delete the gas recirculation sensor so it's throwing the only code now. Still only getting 22 lbs of boost but it spins up a lot quicker and pulls better thank you for your response

Why would you use this turbo for the demonstration? This is not anything near the type of turbo that’s on super duty turbos.

@shanersmechaniclife3164 11 ай бұрын

Sorry, I find lots of people might make this mistake. If my info is incorrect, can you please let me know when they changed? I used this truck because it uses a Garrett variable geometry turbo. Garrett makes the turbos that Ford uses on the superduty. ( not sure if all of them, but many especially the 6.0s ) The truck I filmed on was a cab over design which made visibility of the parts much better. The super duty turbos may appear a bit different but the technology is the same. I appreciate your feedback. Thanks for watching and commenting.
