Help 1994 Isuzu Trooper

I have a 1994 Isuzu Trooper S model 4X4 Auto with a 3.2 V-6. Miles are 145-K
My question is: I have this deep engine knocking sound. Many have thought it was a muffler or manifold leak but all is ok in that department, no leaks.

The vehicle runs very good and has no fluid leaks but this sound is driving me crazy. The oil and transmission fluids and pressure are ok. Dose anyone have any ideas as where to look? Once again itís a deep sounding knock but not like medal hitting anything.

Tough to say without hearing the noise but I would check the harmonic balancer and the torque convertor bolts first.
