    I recently replaced rocker gaskets but I'm still getting odor in the cabin. Took my mom to town and she believes she got carbon monoxide poisoning.
    Someone else brought to my attention that it should not be able to get in there through cabin air filter. Is there somewhere else it may be getting in?

    Your mom cannot smell carbon monoxide, since it is odorless.

    It does not take much oil leaking onto the heads, exhaust manifold, etc. to get a burned oil smell in the cabin. It sounds like you need a complete washdown of the engine and then a careful examination after driving it for a while.

    No you cannot smell it but you can smell burnt oil and exhaust which have co in them. Yes it does need a good wash down and inspection but that wont be happening right away.

    I would go to one of those self wash places and get the power wash wand under there. If you have exhaust coming in the cabin then you have a leak in the exhaust somewhere from the manifolds back. I am inclined to agree with oil leak first.

    is the oil pan wet with oil? it could be the timing cover leaking or front seal.when oil is dripping and getting a cooked doesnt really matter if the cabin air filter is new imo

    Agree with 99 - timing cover or front seal leaking onto exhaust pipe, or rear VC leaking onto rear manifold.

    If you have the resources (or you're in good with a shop that's willing to do it) you can apply mineral spirits to motor from beneath, maybe scrub down some caked areas as well but it doesn't have to be spotless, and drop some uv dye into crankcase. Run it for a few days, then check with a blacklight. Just know that fresh oil dripping on hot surfaces will smoke up a bit, so this isn't for bad leaks. I had this done by a shop that is the local AAA service spot, so their bottom line isn't affected by doing little favors for repeat customers. Something I'd recommend to anybody on a budget!

    BTW you want to do this in the days leading up to oil change to flush out the dye once you've done uv inspection.
