i was crusing up the interstate this morning and slowed down went to hit the fuel again and there was just no ***** in it. I looked in the mirror and the truck was just billowing black smoke everywhere (looked cool but this truck doesnt smoke) and there was no power. i got off the interstate and the truck wouldnt get over 20 mph unless going down hill and just pouring so much smoke i couldnt see the road. boost was 0, egt's hit 1600, fuel psi gauge is disconnected right now and water temp started to get high. the exhaust sounds like the pac brake is closed off(it has been broke for months now) but even if it did decide to shut off some how thats not gonna cause the smoke and no power i dont think. any help please.

 

If the exhaust brake is broke closed, it'll keep your turbo from making boost...starve for air. Meanwhile you're asking for power so your injector pump is giving more squirt. Lots of fuel and no air is smokey.
You might try disconnecting the air inlet tube from your aircleaner to your turbo and see how that runs in case a rat or a bird got in your air cleaner housing and is blocking the inlet air.

 

just did that and the turbo is not even trying to spin

 

Sounds like its time for a turbo replacement or upgrade...

 

With the engine off, does the turbo spin freely? If so, yer brake is blocking. If not, it's time to remove the turbo and see what's got it stuck.

 

Have you tried to spin it by hand or checked the play in it.

 

at first it was not spinning freely and i kept spinning it and it started to spin more freely. i started the truck up rev it up and the turbo is spinning very slowly not like it should be and no boost.

 

If you don't think its the pac I would take it off and check it out, you can get a rebuild kit for it or you might want to get a new one but it sounds like a bad bearing. while you got it off might want to make sure the oil line running to it is not stopped up.

 

www.htturbo.com can get what you need.

 

well i took the pac brake off and thats what was causing the trouble, it was just staying closed for some reason. thanks for the help. do the bearings go bad in them a lot? or could there be smething else wrong with it the butterfly opens and closes easliy by hand.

 

Looks like your turbo bearings are trying to coke (scorched oil in the process of turning solid) up from the heat. Changing the bearings now before any shaft damage should save you money in the long run....or upgrade while it's off.

 

yea im looking to try and get an HX35 from a guy cause im sure running it like i did and gettin that hot did not do any good for the little turbo. there is no play in and out but side to side there is just a very little bit of play...does that mean any thing that i should act sooner rather than later

 

as long as there is no in and out play and you can't make the comp. wheel contact the housing you're fine with a rebuild kit.

 

good enough thanks
