well the dust cover was never reinstalled yet i wanted to make sure it
ran good first seemed like a waste to put that on if it wasnt gunna
run so thats not the problem i thought about moving the tranny back
myself but i dont have very much free time i think i am going to do
that this weekend though i just wanted to explore all my options
before i went and redrooped the tranny for spark knock or something it
deffinetly sounds like i dropped a bolt in my torque converter or
something..... is that a possibility and also too i forgot to fill the
converter up with fluid before i installed it will that do it???? it
had a little bit in it not much though.... thanks for all the help guys

Remove all the Sparkplugs, Thank you can turn the Fly wheel By Hand
real easy and listen for the Knock.
Also Is the Starter Bendix Kicking out ?

Is it a kind of quiet knock? Almost a tick? Does it change when in (n)
compaired to (d) or (r)? Did you pull the dist cap before dropping
trans? Check around fan too. Also, any sound at the crank can "travel"
front to back and vice versa.

so i did that and its not the torque converter or the flywheel i
completly changed my flywheel and everything and had no luck..... then
i tried to see if maybe it was something with the starter nope no luck
there either then i thought maybe it could be from the distributor
getting crushed on the firewall on accident when i took the trans out
replaced cap/rotor no luck there either i checked the oil pan for
dents no dents (oil pick up).i checked my fan blades nothing is
hitting there either. checked my drivebelts they are all fine and
dandy. (transmssion is complety out by the way and its still knocking)
could it be a bad bearing??? if so will a compression test diagnose it
if not what will diagnose a bad motor bearing or bent rod etc....???)
thanks for all the help

the knock is really ierd sometimes it quits all on its own but if i
push the throttle it speeds up like idle is ticka....ticka.....ticka
with the throttle its more erattic like ticka ticka ticka ticka i
dont know its really wierd....... no the engine hasny beens itting
though i was driving it to and from work/school everyday... and it ran
just fine..... sometimes it would make that wierd noise then go away i
forgot tomention that part though but thats when the other
transmission was in it...... so i dont know no i have not checked my
lifters or valves....

Bearings can be checked in frame by removing oil pan and using
plastigauge. Bent rod by disassembly only. Is it a "rythmatic" knocking,
like a steady beat, or for lack of better word does the tempo change all
by its self ie not increasing rpm or anything. You can check the thrust
bearing
with out removing anything except the bottom pulley. You need a ball joint
gauge
Mount the ball joint gage so that "plunger" is lightly against the face of
the harmonic
balancer the pry the crank foreward as far as it will go (this does not
mean go king
kong on it) zero the gauge and then pry the crank to the rear and take your
reading.
Gauge needs to be as close as possible to right angles to the face of the
balancer.
Compression test will only tell you the condition of the rings and valves.
How long has
engine been sitting? have you checked valve lash looking for a collapsed
lifter?

Thats a rather important part you forgot to mention. All of your posts
talk about after the tranny and things like did I possibly drop a bolt in
the torque convertor when I replaced the tranny. along with others here
wondering if you installed the torque convertor incorrectly and as
such bust the front pump internals, when all along the noise was there
before
any repairs were made.

i had a similar noise on a chev 350 that would only happen on throttle
up and not on idle, the timming chain was stretching just enought to
contact the bottom of the timming cover...was an easy fix.

i had a similar sound comming from a 86 cutlass with a 3.8, the
timming chain let go...after much BS replacing the chain, i didn't get
all the shrapnel from the chain out and it cause a block on one of the
lifters, every once and a while it got enought oil to go quiet....was
another easy fix, i got rid of the POS!!!
