I went to Azusa Canyon today for some mudding. I did some river-crossing/ driving up and down the river, mudding, and rock climbing. It was a tough day for the old beater and daily commuter, but it runs just fine like we are used to.

Here's the problem: When cranking the engine, there is vibrations coming from what seems to be the engine bay. However, the engine runs just fine when popping the hood, with all fluids topped out as they should. The vibrations are only noted in the car, and increase when revving the engine. On the highway, this low-pitched vibration/howl increases as speed increases. It isn't the tranny as far as I know, because it is there even when standing still and no gear is engaged.

Has anyone else experienced this? Any suggestions? I'm thinking it could be the rubber things the engine sits on to dampen vibrations, but I am not sure as I don't know where to look for them.

Any help would be appreciated! <img src="/forums/images/graemlins/scared.gif" alt="" />
