Thanks mate...ill give that a shot aswel.

Allthough Ive had another listen to it..and im convinced its lower down..it cant be heard up top...and its only audible at idle.  Its just too much of a clack..rather than a tick....plus the cold start knock after sitting a few days.

 Do you know if its possible to replace rod bearing shells with the motor still in the car?. 

Hi, I know they have an ecu that controls the mirrors..i think its under the dash on drivers side..along with a couple other ecu's. This might be worth a check.  

Gday all, i have a 1UZFE celsior, and its developed a cold stark knock after sitting a few days, and once warm..it has what i suspect is a light rod bearing knock?  Im new to these motors...so I have no previous experience diagnosing noises with it...any insight into this will be appreciated.  

I can hear this when im crouched down at the front wheel..or if i have the door open while warming up. If i stand up outside the car..i cant hear it.  Its sound is a "clack" and it rythum is..."clack clack clack...(pause)...clack clack...(pause)...clack clack clack"  this is only audible at idle.  There is also a slight motor vibration thru the car thats also developed in the same time frame... im unsure  if its related? The car runs and drives nicely otherwise.  

If this is a bearing failure...is it possible to just install a new set of shells?...provding the crank isnt scored or damaged?  

Thanks in advance.
