So im pulling on to western from avent ferry (taking a right), and i gun i through 2nd gear. Around 5-5500 RPM's i hear this BANG and then i hear pieces of something bouncing around underneath the car (or so it sounded). I let of the gas and the car returns to idle normally and there doesnt seem to be a problem. I keep on driving to my destination keeping an eye on the gauges. All seems well. When i come to a stop i notice a slight vibration throughout the car, when i give it some stick in neutral the car vibrated horribly (didnt do it in gear).

So i drive home and as im driving i hear another very similiar sound followed by some in car vibrations which then dissappeared. I pull to a stop in my apartment complex and rev it in neutral and all seems well (no vibrations). At idle, however, there is still a slight wobble throughout the car.

So, my first diagnosis is that an old/poorly bolted engine mount gave up the ghost, which was then followed by the other one. Thoughts?

Tomorrow ill through it up on stands and check it out (unless someone has a lift laying around ; )

are you running a water pump with a metal or plastic impeller

[Edited on January 19, 2007 at 8:23 PM. Reason : and have you looked at the belt/pullies? are all the fan blades still there?]

not sure, i got the car about 5k miles ago....it seems that i remember nick or ahmet saying that it had been replaced with the metal kind, but again. i dont know for sure... The temp wasnt raising at all, on a sidenote.

exhaust hanger might be broken

1/19/2007 8:32:17 PM

ah, fan blades. Upon closer inspect about 6 blades broke off and they were pointed down, i had to rotate it to see.

It seems as though the radiator moved back a bit upon acceleration and caused it.

i would drive it with bent fan blade, they're apt to come of an go through the radiator

are you sure your floorpan didn't fall out from dangerous manifold pressures?

1/20/2007 9:00:33 AM
