Name that noise

[daddy_dandy]

Let's play a game nobody enjoys playing. It's called, Name That Noise!!!!!

Today's contestant is a 1997 L31 which just passed 260k on the clock. Let's give her a big 'round of applause!!!

Noticed this yesterday evening. Driven it about 100 miles and it's getting worse. I don't plan on driving it anymore. Well, not further than the driveway anyways.

Crushed lifted on your left bank would be my guess, in case its just stuck I would change your oil and seafoam your upper cylinder's through the brake booster but it sounds a lot worse than the standard stuck lifter
