Bad piston wrist pin

A couple of months back my Mustang started to occasionally sound as if it was detonation on one of the cylinders. It's been in stroage for the past 3 years and my Dad starts it up a few times a month, but he said the tick has gotten a little bit louder. We are going to pull the motor when I head back for a visit, but have you guys had similar experiences with wrist pins in the past? What did it sound like? Did it progressively get worse over time? Dad thinks it is either a wrist pin or a piston skirt, but we will fix it either way.

You guys had a wrist pin go bad or a piston skirt go bad? Thanks,

Would it be noticably different if I pulled a plug wire on the suspected cylinder?

Right now I can't because I am still in Germany, but I will be with the car at the end of the month. I'm just trying to prepare for what it is for $$$ and time. I am very curious to see what it is though.
