Rod bearing replacement

Hey guys,
I picked up a 2007 Suzuki SX4 AWD a few months ago. It has around 160k miles on it. On Tuesday just before I left on a business trip, it started knocking. As soon as I heard it, I pulled into the closest parking lot and shut it down. I checked the oil and it wasn't showing on the dip stick. The weird thing is that it was changed right before I bought it and I've checked it every couple of weeks and the level was fine. I can't find a major leak anywhere and it doesn't seem to be burning oil either.

Anyway, my main question is about changing the rod bearings. I don't have money to buy a used (much less rebuilt) engine. I drained some oil out this morning and there are no chunks or even large enough particles of anything that can be seen. Only a metallic sheen in the oil. Do you think that this is evidence that I can do the rod bearing replacement with the motor in the car? I've done several engine rebuilds, so I know the basics. If I had the time and money, I'd rebuild the motor, but at this time of life, it's not really possible.

If any of you have done rod bearing swaps with the engine in the car, do you have any tips? And what were your results? Did they last a decent amount of time?

Thank you for the help!!

I have done a few rod bearing changes in the car in my life for all the same reasons. My main bit of advice is to get the engine bay and cross member as clean as you can before starting to work. Not sure on the SX4 but on the sidekick it don't look terrible. The other major point is to make sure you got room to properly torque the rod bolts. Last item will really set the success on the length of the repair. I did this to an old Lincoln I had when I was a kid and drove it another 100k. While you are in there I would at least pull one of the rear main caps to see if you got damage. OR just say fu** it and live in denial and throw in rod bearings. The last time I was going to do in car bearing swap on a race car I discovered the crank was jacked up and had to pull the motor anyway.
