View Full Version : Something Broke - Turbo?

11-09-2002, 03:34 PM
I just went and fueled up and I had a straight stretch of road and I thought I would open it up a bit. I was going maybe 50 but I was burying the Boost gauge. Odd of a sudden I heard a load bang under the hood and my boost went to zero. In the rear view mirror was a cloud of white smoke.

I was just around the corner from my house and when I got home I looked at the exhaust piupe and there was oil coming out of it. Also, just before I parked a dash light came on to check my gauges.

Once before I blew a seal on the turbo and the sound was very similar but I didn't have the smoke of the oil. This has scared the !@#$!#@$ out of me. Before the fix was pretty basic.

I hope this isn't terminal for my turbo or anything else.

I do have a backup turbo. Is it safe to drive this truck the way it is to get the truck to my mehcanic which is about 40 miles away?<br><br>I have a call in to him to explain what happened to get his advice. I'm not moving it until I hear from him.<br><br>Does this sound like just a seal or could it be that the turbo is just thrashed?<br><br>

Pull off the air intake boot and see if you can spin the turbo by hand, if it is hard the shaft broke. or the main bearing siezed.if so don`t run it as it will push ground-up aluminun into the intercooler and it aint coming out easy<br> Danny

<br>Sounds like the oil seal in the turbo went TU. If you continue driving it, it will lose oil through the seal and into the intake system.

Thanks guys... I appreciate the input. When I was pulling into my driveway the first thing I thought of was to get on to the forum and check with the gurus.<br><br>

If you went from full boost to zero, I figure the shaft broke or the turbo siezed. Either way I wouldn't drive it. Sorry man. :'(<br><br>J-eh

Hold up. It could have been something as simple as a boot blowing off. Check all your pipes where they connect with rubber boots. That's the most likely case to start with. Then check the turbo...

Can a boot coming off cause oil to leak like that? I have a trail of oil from my exhaust pipe all the way up my driveway. My driveway is about 300 yards, a lot of oil.

was in a cummins shop the other day and saw what was left of the turbo...nothing. fortunately it went out the exhaust rather into the intake. good luck man!

No. There wouldn't be that much oil from a boot blowing. Unless there was enough oil in the pipes to drain like that. Oil does get in these intake pipes but not that much.
