I have a knocking noise when in park. What is causing this noise?

Hello Mr Hampton! We can do a "no charge assessment" of the car to tell you what's going on -- it's possible "bad oil used in the past" (or frankly "NO OIL used in the past" as that can cause very serious engine damage and you could have actual serious "top end" engine problems -- have you owned the car since new? How many miles on it? Please bring it by Markert Motor Works -- we are just up the road in Lawrenceville. We can do a no charge assessment and if it requires further analysis (i.e. taking the top of, compression, etc) we can let you know.
