....Ok...Ever since I replaced the intake manifold last(2014) March I have had a very faint burning oil smell...i replaced the 2 rubber hoses on the dpfe sensor and I thought I had it solved . Its not using any oil in between 3000mile changes...Where could the smell be coming from? exhaust manifolds are not leaking...I just replaced the pass side 2 years ago..any ideas? Pcv valve?

 

There are valve train covers on each bank.
They can leak right onto the exhaust manifolds.
Good luck.

 

....Valve cover gaskets? If so I'll have to check them.....I just found it ironic that ever since I changed the intake manifold, I got the smell
