How much will it cost to change engine bearings in a 1997 nissan altima?

My mechanic says that my engine's car bearings are worn out, and he would need to replace them. can he really replace the bearings by themselves? how much would something like that cost?How much will it cost to change engine bearings in a 1997 nissan altima?
What is the car doing?



Is it knocking...not ticking (all altimas have noisy timing chains, they sound like a light metallic slap or tick every few seconds) but a constant loud ';knock, knock, knock'; that increases with rpm?



Does it smoke bad out the tailpipe?



If not there is no reason for a rebuild.



If he is pulling the engine it would be silly not to get the entire engine rebuilt. If the bearing are worn out then it is advisable to also resurface the crankshaft. This is what the bearings sit against To do this the entire engine has to be taken apart.



If you do need one it will be cheaper to get a used engine from a junk yard. Most yards give warrantys. Get at least a 6 month warranty. You can pick up a nice used, lower mileage then you have now, for under $400 if you shop around. You can have it installed for $800 at most.



Rebuilding your engine will cost about $1500 plus the cost of install, about $800. Save yourself more then $1000 and find an used engine.



or...if the car is running ok and it is still passing whatever local emissions laws you have...just keep driving it!
