OLSD feels awesome.. issue down low.

Ouch...

Also, additionally:
Are you sure that the crank pulley/balancer is ok...?
What about the flexplate and/or TCC bolts...?
Are all cylinders firing (check if all header primaries are equally hot)...?

Have you tried a compression test and a leakdown test...?

Only thing I did was tear off the rockers and pulled the p-rods out.. All looked good and i changed the oil to see if anything was inside the pan and it looked fine.

Ill look at the pulley/balancer...

I can hear it under the car.. ill look at the TC bolts.

[waterbug1999]

verter bolts and flywheel are fine..

the balancer/crank pulley looked fine to me, dont know what i would be looking for though.

If those were loose there would be a similar noise.

A very fast way to diagnose the noise would be by disabling one cylinder at a time while idling the engine.

Either by pulling each injector connector or with DVT (F12) in the scan tool.

If a rod/bearing is the origin of the noise then when the noisy cylinder is disabled the noise will stop.

That's good strategy... with an F-body it may be easier to do it with DVT.

i tired that, the noist still was there no matter what cylinder I turned off..

Im thinking I have a bent valve somewhere, im going to be doing a compression test to see if I can narrow it down to a certain cylinder or a certain side and save some work. I know what the PSI was last year so ill know if anything is low.

Jody, let us know how it goes (post pics if you can).

[waterbug1999]

I did a compression test... I knew something was up on the driver side, here are all 8 cylinders.

1 = 240 2 = 210
3 = 180 4 = 210
5 = 185 6 = 200
7 = 160 8 = 210 PSI

looks like the driver side haed has the damage, i guess ill pull it and see how bad. Hopefully its not terminal.

[waterbug1999]

well, here is what I found and I am assuming somehow its causing the "clank" "clankity" "clank" noise I was hearing..

Im down for now, but will be back next year. Thanks for everyones help.

ouch...
