    Head resurfacing, all valve stem seals replaced, hot tanked.
    I just pulled my EGR tube 4k miles after cleaning and there’s a baked on oily sheen, so she’s definitely burning oil from somewhere.

    What's the oil consumption been like, historically?

    But yeah, you mentioned oily plugs.

    I assume they lap the valves and checked if it’s all sealed?
