GMC Repair: venture van engine noice, venture van, alot

Question
I have a 2002 Venture that has "diesel like" sounds coming from the engine when running.

Answer
Hi
There are ALOT of things that can make noises. It could be a misfire. Could be something loose externally. It could be something internal.
My best advice would be to take it to a repair shop YOUR familiar with and have them listen and diagnose noise.
Anything that moves on a vehicle and alot that doesn't,  has the potential to make noise. So anything I tell you would just be general items, like stated above.
Good Luck
