    You smell it under the hood or or the pipes? How many miles on the engine and does it leak and/or burn oil?

    As [MENTION=1]Steve[/MENTION] is saying, usually when you smell oil burning, you have an oil leak.

    So, before you pull the engine, lift the hood and look for an oil leak.

    If you hear a knock, it is probably because the oil level is low.

    Find the leak, fix it and top up the oil and you may be good to go.

    That is usually a sign of worn valve guide seals, not rings.
