    Hey All, hoping you can help us out...

    I was driving down the interstate today when I heard a loud pop or snapping sound followed by loss of power. I looked in my passenger mirror and saw so TONS of whitish smoke coming out the stack, that smelled of burnt oil. I limped the truck off the interstate and stopped at a truck stop about 1-2 miles away, where we are now parked. There is oil leaking below the turbo.

    -How much has blown turbo cost some of you in the past? Seems I have been reading about 3-5K... What would constitute this difference in price?

    (our truck is a 06' KW T-600 with a 475 Cummins ISX, we are new owner ops and had truck 7 months)

    -Did I do any extra damage driving the 1-2 miles and should we tow the truck the 2-3 miles to the shop tomorrow or is it ok to limp there?

    -Is there any way this could be a broken clamp or am I just dreaming? :biggrin_255:

    Any advice or comments are GREATLY appreciated!!! :biggrin_25519:

    Thank You!!!!!!!

    i'm no expert, but i'd make sure it is full on oil and keep an extra couple gallons and try to limp it carefully. a tow bill is outright rape.

    I've blown 3 turbos...all 3 times it was tons of black smoke, not white (Burning a bit "rich" without the turbo, hence the black smoke) . White smoke usually means its running lean...or pumping raw fuel out the exhaust.

    I have no idea what it cost, all 3 were company trucks.

    You sure yours is not an injector problem?

    As to whether driving on a blown turbo will damage anything,,,sometimes yes, pieces and parts get all up in the air charge system...and sometimes no, nothing gets damaged.

    Try asking around on the CB if there is any local mechanic shops in the area. I've heard the average is $1,800 to $2,000 to replace it by someone not trying to rape you. Try asking a mechanic in the truckstop if there is one. He may do the job on the side if you can move the truck out of the lot.

    Blown turbos are OK unless the fins break off and get sucked into the engine.

    Good luck!!! Sucks being at the mercy of someone else in a strange town.

    Thats what we thought at first when we saw the white smoke, that it was an injector, but after looking under the hood at all the oil below the Turbo, that made us think it was a Turbo...

    What do you mean when you say "pumping raw fuel out of the exhaust?"

    (sorry I dont know too much about under the hood and my husband is asleep so I am trying to do some research before we get to the shop.... Thanks for bearing with me! :)

    Pumping unburned fuel out the exhaust...can be caused by a couple different things. (valve problem being the most common...I guess)

    I've also never had an oil leak with a blown turbo...(1 was a C12 Cat, 1 was a C15 Cat...the last one was a Detroit)

    I'm not saying it can't happen though...I'm not "up to date" on the plumbing in these newer engines.

    Hmmm... Maybe we are totally wrong thinking it is a blown turbo...

    If it was an injector could that cause oil leak?

    The bearing, shaft in journal, goes out and the shaft breaks, yes, you can get oil below the turbo. The charge air cooler gets enough oil through it to get into the intake, and you can get a condition called run on.


    Blowing the tip out of an injector will put raw fuel into the exhaust. A bad injector in my experiance will cause dark smoke.

    Look closely(or have your husband look when he wakes up), the piping coming loose from the turbo and dropping down can cause all of those things you describe, too. A 2004 Detroit did what you described and had about the same symptoms. Road rescue brought a clamp and I got it home, but one of the nitrile boots had a hole torn in it and had to be replaced.

    Hmmm...OK, makes sense.

    I guess I was just lucky on the oil leak issue.

    The clamp...if the turbo blew, it will be broken and/or popped off, right?
