I have a 99 camry it started making a knocking noise the other day I have a mechanic look at it he told me it is a rod bearing the first rod bearing so I called around for parts to see how much one would cost and they said there is a standard rod bearing and then there is a.25 millimeter rod bearing or a.50 millimeter rod bearing which one does my car have and how can I tell without disassembling it and having it resembled I can't afford to pay double the labor cost please help

If the engine was never rebuilt, it will still have the standard ones. However, your mechanic needs to check bearing clearance on all rods and main bearings. He needs to use what is called plastigauge or a micrometer to determine the diameter of the crankshaft. If it has too much wear and you just replace the one bearing with the standard size, chances are it will be bad after a few miles and start making noise again.

The other sizes you mentioned come into play when the crank is cut / machined. As the diameter of the crank gets smaller from machining, the bearing has to be thicker to compensate for the added space.
