    200 HPDI Vmax Rod Bearing or Crankshaft Lower Bearing

    So long story short I picked up an 05 HPDI Vmax (first year of the 3.3L) on the cheap because the original owner was told a rod bearing was going out...specifically that the bearing is quiet when its cold but starts knocking once the engine is warmed up. Got the engine on the stand and tore the front of the engine off however all the bearings feel tight. I brought all the pistons down to BTDC to stick my hand in and feel the rod bearings and they all felt good. Rotated the engine to bring them up towards the head and rotated it back a little so I could push on the piston but still no movement. When I rotate the flywheel back and forth I get a clicking noise that sounds like it's coming from below the powerhead which points towards the lower crankshaft bearing or something a little lower than that. My concern is that he may have mistook the rod bearing knock for one of the lower bearings so any idea how you would diagnose this? And any of you seen rod bearings that are tight when cold but loosen up when warm or do they usually make noise all the time? Lastly if you had an engine tore down on the stand that seems to check out would you throw a rebuild kit at it even if it might not need it?
