Well I just spun the #2 rod bearing and now have to replace the crank and the con. rod. Can this be done with the engine still in the car?? I have the engine pretty much torn apart. All that I can see left are the mains, and the torque converter. Also can you remove the piston out of the bottom of the engine?? I have heard of people doing this before but am wondering if it is possible with a GN. I know that you will say just pull the engine but I am wondering if this is a possibility.

Thanks
 
I'm pretty sure you can pull the crank with the motor in the car, although I think due to cleanliness and risk of damage I'ld just pull the motor. As far as the piston, yep, you can pull it out the bottom. BUT, you won't get it back in through the bottom that I could imagine. Maybe there's some special way of doing it from the bottom, but I can't imagine a way.

My answer to your question is; "Yes", it can be done,,, but,,, DON'T DO IT!!! If you have spun a bearing, then you have had a major failure, and that bearing material is now scattered throughout the motor. I've done band-aid repair jobs like this many years ago, and would never recommend it to anyone now, per my own learning curve.
If you care about your car, and its performance, then you should be willing to repair it in the proper fashion! You can do a temp fix on it, but you will inevitably trash the whole motor, as the rest of that scattered bearing debris digs itself into all your other bearing surfaces. If you cannot afford to pull the motor and have it freshened, then I would simply suggest parking it until you can. At the very least, you'll need all new bearings, rings, and all the other usual stuff. You can re-use your pistons, etc, as long as the block cleans up with a minor honing.
Others may argue this point, but, any professional/performance engine builder will tell you that you are doomed for disaster by attempting the method you suggest.
Just my opinion, (and the pros I've worked with over the years), so take it for what it's worth...
