    I didn't want to necropost on Den49's thread, but I have a question regarding the same black hexbolt mentioned in it.

    I have a 2010 with 208, 000ish miles. While doing an oil change today I noticed a leak ended up appears to be coming from this bolt?

    Likely unrelated:
    I've been planning to inspect the PCV and spark plugs for current condition, because I'm unsure when they were last addressed, as I only started doing my own maintenance within the last couple years.

    I feel like recently the car is struggling a bit, and I have to push her harder to get up to speed sometimes. :(
