i just bought a 02 2500 and when i shut off the motor, it makes a squeak.
that and i have an oil leak that i was told had to do with a vacuum?
the leak is looking in the bay right side midway down the motor

 

The squeak is just from the engine stopping faster than the belt stops.

Is the leak coming out of a tube that comes from the in front of your Injector Pump?

 

Mine squeeks too. the Breather bottle (aka puke bottle) is probably causing the leak. Take it off and drain and clean it up. They all do it. By the way Welcome to the site! Its a great place for info on these trucks.

 

Mine use to sweak. I changed the belt tensioner and put a gator belt on it and it hasn't sweaked in a year.

 

Get yourself a GoodYear Gator Back belt and the squeak should be gone (worked for me).

 

Yep. You need to clean your puke bottle and get you a gator belt. It'll fix'er right up! Welcome to the board!!

 

Mine has always done it from day 1. It doesn't hurt a thing.

Mine will stop next week after installing a Gatorback belt.

 

thanks guys, making that leak stop would be nice. my whole underside is covered in oil/gunk.

 

You said your leak was something with the vacuum, its possible that your vacuum pump seal is leaking. Mine just started to and I guess its a fairly common problem but can be fixed with a kit from fixinrams.com.
