What could I have hurt?

[DERICKS]

I was leaving work today and my car was still cold and i hit the throttle in first gear not hard but enough to make it hestitate then come on for about a 1-2 second burst, no high rpm. Imediately I had a new noise that sounds...no kidding like a heat shield on a catelytic (sp?) converter came loose...except I have none. The noise is not all the time but does come up in each gear with a little rpm. No change in oil pressure or how it runs (no miss)....just a disturbing noise. How could I have hurt it? what my be wrong?

Was the sound a bing noise,you should always let it warm up a bit.

converter bolts or flexplate?

Trans dust shield hitting the bolts?

I had something like that with a 318 in a 1/2 ton truck. When I would make it pull a little harder than normal the crank would move enough to allow the 4 flex plate bolts to hit the front trans shield.

A couple votes for flex plate and converter bolts! I'll get under there tomorrow

No bing..and yes i know i should always let it warm up

I agree on checking flexplate bolts. I had 340 that took out thrust brg on crank and it would shift and flex bolts would rub on inspection plate.

Cgeck the flexplate

The torque converter bolts are tight and i cant see any cracks but I cant get all the way to the crank. Would a spun rod bearing drop oil pressure?
