    You can feel on the valve cover.
    Its running jacked up.
    And 2 mechanics have said the same thing.

    do a compression test and if one cylinder has no compression try putting a little oil then retesting that will tell u if its rings or not

    put a grenade in the engine bay, shut the hood and run away. then you wont have to worry about it any longer.

    Army surplus store. Fill that fucker with gun powder, slap in a fuse, and you're back in business.
