Hi i have an issue with my truck. I really need help with it.. i have a 2011 chevy silverado 3500 duramax dually truck. And im hauling atrailer with it. While i was driving it i notice that there alittle knocking knoise coming from engine compartment. I thougth it could be a low oil level at first i had to drive it to nearest auto parts store to get an oil.

I am sorry your having this problem

from the sounds f this the engine to have 6 quarts of oil added to it was low enough to cause a low oil pressure or oil starvation situation which caused a failure of a lower end crank bearing and or a valve train failure

with the oil full now and it still making the knocking sound i am sorry to say there is some internal engine damage done from the low oil and the engines oil pan needs to be removed to inspect the bearings next

but do not drive this truck as more damage can be done to it
