Tengo una 2005 chevy silverado 2500 motor 6.6 me avienta mucho humo y aceite por el escape ya remplase el turbo pero sigo con el mismo problema Mechanic's Assistant: How many miles are on the Chevrolet? Is it an automatic or a manual transmission? 224000 es automática Mechanic's Assistant: Are you fixing your Silverado 2500 yourself? What have you tried so far? Si remplaze el turbo Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Yo creía que podía ser el motor pero cuando quite el turbo nomas por la salida del escape tenia aceite por las entradas esta secó

Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. With the mileage, I suspect the valve seals. You need to do a compression test and leakdown test to determine if it is the valve seals or the piston rings. Thanks for using Just Answer and letting me help you. I hope I provided what you needed. If you find more help is still needed, let me know by listing out any remaining questions you have on this concern. I hope the remainder of your day is well.

Hello Eric so this is whats happening with the vehicle. It is throwing/leaking the oil through the [exhaust](/topics-exhaust-chevy/) outlet and it is completely dry through the exhaust manifold. And my concern is that it doesnt Just leave a drop or 2 of oíl where the exhaust is at but instead a big puddle.

HI, Does tend to point to the turbo. did you install a new, reman, or used turbo

Ive installed 3 turbos already, first 2 remans and both did not work then we installed a New turbo and it still leaks. The weird thing is that I unplug the vane position sensor and the fumes stop, so there is no more smoke and apparently it stops leaking too
Automotive Expert
HI How is the oil pressure? Wondering if there is an obstruction some where that causing pressure build up to cause the turbos to leak every time

The oil pressure seems to be normal its between 40-45 psi I algo checked where it sends back the oil and everything seems to flow pretty normal
Automotive Expert
HI, Hmmm, any issue with lack of lubrication in the turbo?

That might be the problem because with the second reman that I installed, the bushings broke I believed thats what they are called
Automotive Expert
HI Ok, there is a service bulletin out for the #4 cam bearing being spun and blocking the orifice that supplies the turbo. I have attached it a pdf file for you If this is found to be the case, GM states to replace the [engine](/topics-engine-chevy/)
