oil coming from valve into turbo charger
Diesels do not have pcv valves. Pcv valve are on gas engines only.
it's located on pg 61222 of gm shop repair manual
sounds like you need a new turbo since these vehicles dont use a pcv valve
The last two answers were wrong. Duramax motors have a Pcv valve. It stands for positive crankcase ventilation and every engine has one that I am aware of and it's to relieve the air pressure built up in the crankcase from the pistons moving up and down. The Pcv allows atmospheric air pressure inside then crankcase. If there is a lot of air pressure coming out of the Pcv you could have bad valve seals or worn piston rings allowing massive amounts of air being forced into the crank case. The Pcv valve on 2003 and older have the Pcv built into the valve cover. It is a box shape cap that has a spring and diaphragm under it. Old question just thought I would clear that up for the 2 people not so mechanically inclined that answered last.
depends on the year of the duramax, some do have a pvc valve one is on the valve cover on one year and on another year the valve is down at the bottom of the engine it screws in, i would check with your local dealer, the should give you an idea, if the turbo has an line follow it the other is just mainly a vent on the valve cover, is the oil coming in or coming out of the turbo?
