The truck has 33289km. I've had it since new. Always taken really good care of. This would be the first engine trouble I've had. Please help.
Why is oil coming out of my muffler?
How much would it cost? on 2005 GMC Sierra 1500

Better have a mechanic confrim your findings. For oil to come out of the exhaust, it would be running like crap and smoking intensively! That stuff comming from the weep hole in the muffler is most likely condensation mixed with exhaust soot, kinda looks like oil. More obvious in cold weather. Now it may have a leak somewhere and is collecting on the muffler. 33289 km is only 20,600 mi. That what the odometer is showing? I really don't think you have any problems with the truck!
That's good to know. It actually has 332089km. It does blow black smoke and runs rough when idling but when I'm on the highway it runs and sounds good. I run my company out of the truck and has pulled a trailer it whole life. Thanks for your help.
