i think i hurt my motor!!! driving today and i notic a knock!! you realy have to lisen to hear it. sounds like its the vale train. it has a full tank of 93 soo i know its not that. i might have broken some push rods or a lifter?!?! sunday i took my car out for a ride on R3. a lil boxer s pulled up beside me trying to get me to spped up or race. i was like what the hell its nice out so why not. i ran it hard for a while. mayb thats why?? the oils full and i got 40-60 pis oil presure. no lights are on.
you guys got any ideas?? my buddy russ is stoping by tonight to take a look. he said not to drive it. i think i am going to pull a vale cover and take a better look!

it looks like i might have spun a cam bearing! when i gas it, it gos!! runs fine just make a nose like i have rocks in my motor. i had it looked at by my momthers boy friend whos also the guy that does all the work to the car. he said it looks like i might need a new block/motor! hes going to make some calls today and see if he can get his hand on one. he has a few 350 motors but no lt1s. the car is not leaking and oil and when i rev it up it only gets a lil louder (the noise). you realy have to lisen to hear it. sucks but what can you do.
so now that the motor has to come out what mods should i do lolol !!!!
got an lt4 hot cam but i waiting its out of a friends car....

if it was cam bearings wouldnt you notice an oil pressure and if it was a rod bearing its quite but when you rev it up it has an unusial sound kinda like a stick on a chain leenk fence like Ziippp or like a loose fan belt that slips? deffintly check top end first

Sounds like a rod bearing to me also!
But like these guys said, check stuff before u pull it. I checked everything I could, from the W/P drive to the heads (rockers, blah blah).
Pulled it and it was my #1 rod bearing, crank is toast. Has a nice groove!
Good luck!

If it is a rod bearing, you can start by pulling spark plug wires one at a time to see if the noise goes away, when it does then you have found the cyl. that it is in.

Rods will also get quieter with a load on the motor. Put it in gear (or slide the clutch out a little) and the noise should quiet down considerably. Go back to neutral and the noise should get louder.
I just bought my '95 T/A 3 weeks ago with a horrible sounding knock - I found 3 bad rod bearings in it #2, 3 & 4. In process of re-buillding now. #3 rod bearing was completely gone..good 1/8 clearance all the way around between the rod and the crank journal - and the motor STILL held 40 psi of oil pressure. Figure that one out....
