Hello,
Did you recently have the oil changed? If so, that could be what's causing it. The filter doesn't come off without dumping oil on various mechanical parts. Unless you have the parts covered w/ towels, the oil ends up on the exhaust pipe, giving a odor of oil burning.
If not, check your valve cover gaskets, even though it's new, it could have still started leaking.
Later now,
Clint
