Bad rod bearing

[GSX92AWD]

Ok check this out, I have a knock and there is a chance that it is a bad rod bearing. If that's the case does the motor have to go to a machine shop or can I just replace it?

You will at least have to remove the crankshaft and take it to a shop to verify that it is not damaged - it would make sense to have the crankshaft polished if it is still within specs and install new bearings while you're in there.

you dont really need to take it to a shop.. if you have the right tools you can do it at home. although it would be alot of work to replace a thrust bearing. while your in that area of the engine (if you have the cash you might wanna consider puttin somethin else in there. as for checking the crank shaft (properly) all you reall need is i think a 3" outside micrometer. as for the crankshaft going back in, welll you're gonna need a dial indicator to check endplays. there's alot of other things that would need to be done in order for it to be done proper but it's gonna take more cash. if you do it yourself, just make sure you prime the engine afterwards.

You can usually figure that someone asking about this sort of thing doesn't have the tools nor experience to undertake the job.

I can get the tools with no problem. Experience though, you can't just walk into the store and take some off the shelf. So lets say I just wanted to buy a motor already built, where would be a good place to buy from? Is it worth buying a new one as opposed to doing a full rebuild.

Id say rebuilding the engine is more satisfactory and can be cheaper. Depending on how you build it. If you really want to build it up of course its gonna be some money but its cheaper than having someone else deck it all out. Id say do it yourself. Me and my dad spent about a $1000 or less rebuilding mine. Alot of stuff in that was batteries, tires, shit like that so we spent less than a $1000 to rebuild mine. My new crank was $400. I bought my car with a spun bearing and when we took the crank out it was all FAWKED up. Now it runs like a dream. No thanks to the previous owner who sabotaged the engine becuz his car was getting repossessed but hey i got a nice car for cheap. Im not complaining.

 

[GSX92AWD]

Yeah but what did you put in it. If I rebuild with high end parts(everything forged and so forth), then with all the machine work to the block and head it's going to be about the same price as buying a built long block right? The satisfaction part I could see because there is a sense of pride and accomplishment when you work on your own car but with me installing it myself I think that would give me enough satisfaction.

i rebuilt my own engine with better internals and still ALOT cheaper then building an already built engine....
