Horrible Noise From Engine - 10/14/2005 8:55:17 PM    cantdodgeitramit   Posts: 5 Joined: 10/1/2005 Status: offline I have a 2004 1500 4X4 with the 4.7 and a 5 spd manual, and due to the extreme flooding here in coastal south jersey this past week, i was forced to drive through a good 2.5 feet of salt water in order to get to my house. Just today, a horrible grinding sound was coming from the front of my truck, it sounded like something rubbing against one of the brake rotors. However, I then realized that even if the truck is not moving, if I rev it up to about 1,500 rpm or more, the noise occurs, so it must be in/on the engine. It sounds normal at idle, but occurs whenever I give it any gas, which leads me to believe that it is something attached to the belt. (Seems to loud from outside to be anything internal). I feel that the main suspects are the alternator and/or idler pulleys. I am not sure if this noise is directly due to salt water intrusion, but I would think so. Any thought or suggestions would be greatly appreciated. Thanks in advanced. _____________________________ 04 Dodge Ram 1500 4X4, 4.7, 5spd, K&N, Jet Chip. 86 Pontiac Fiero SE, V-6, 4spd, Nexo 16s.

I looked under the hood with the engine running, It sounds like it could be the idler pulley, but it hard to tell. It does not sound anything like a belt squeal. Everything turns and operates normal, the truck runs fine...other that the noise. (in reply to Patrick) Post #: 3

But as I said the noise has not affected any performance of the truck, so I am hoping for the best. Big Dodge Ram, I do not believe that it is ne thing on the trans, b/c the noise occurs both when it is in gear and when in nuetral, moving and stopped, and at any RPM above idle. Thanks for the suggestions though guys. _____________________________ 04 Dodge Ram 1500 4X4, 4.7, 5spd, K&N, Jet Chip. 86 Pontiac Fiero SE, V-6, 4spd, Nexo 16s. (in reply to Patrick) Post #: 7
