Hi everybody, new to the forum. I have an issue with my 1997 Suburban. It works fine, and when using it for more than 30 min., sometimes it feels as if the turbo stopped working, and i notice smoke coming from the exhaust. The first time it happened, I had bought a diesel filter, so I turned off the engine, change the filter and worked again like a charm. The second time it did the same, I was just around my house, so I parked and started the car until next day, with no issues at all. I'm thrown as to what the problem might be. I thought it was the diesel filter, but now I'm wondering if it is something with the turbo.

If anybody can gel, I'll be very thankful.

Regards
