Have a 95 silverado 2 wheel drive, long bed ,standard cab. 350 V8. Has 52000 orig. miles. Listening with a stethascope I hear a rattle while listening to the oil pan. Can also feel a vibration when laying my hand on the pan. Truck runs and drives smooth. Bought new , so I know the miles are legit, oil always changed. Is this something I should be worried about ? Where would the sound be transfering in from? Oil pump? Might drain oil and peek in the drain hole with a borescope. I have a couple other 350 v8 to compare to, but not had the oppertunity yet. THANKS for any suggestions.

  PS: Here's pic of the 2014 wheels I'd like to run when it's not winter. Stuck my finger around new wheel caliper setup. Very little clearance. I suspect these won't fit, but won't know for sure till I try. Edit: And my first mod. Stubby antenna from the old truck.

  I bought it today and brought it home. They still owe me the bed liner, remote start, and they also agreed to get me the flat black bumpers to replace the optional chromes ones. While some folks may think I'm crazy, I think they'll look a lot better with all the other black stuff. Blacked out grill, mirrors, running boards, dark essentials Chevy tailgate lettering along with the black Silverado and Turbomax emblems. I do want replace dark essentials Chevy front grill emblem with the base level gold one. The 2.7 4 seems to run well and push a 1500 along just fine :).

  I did plug the vacuum line and the rpms where ok. I also tighten the booster line going into the intake. It was a bit loose and that didn't make a difference.
