Balance Shaft Question

Hey guys, my balance shaft (the one driven by it's own belt) on my 90 eclipse gsx has gone out and I'm wondering how hard it is to fix or if I should just get rid of the belt that drives it or what. Any comments are welcome! Thanks, appreciate it!

Ah, gotcha.

In any case, I'd still pull the pan to see what you can see. You did say there wasn't metal shavings when you drained the oil last time so, optimistically, it shouldn't be a complete loss.
Yeah I'll try to. But it's going to be a few days before I'm going to have the time to fool with it. But I'll post an update when I do.

I've had way worse. Take a breath and keep going. You can remove the front case with motor in the car but it isn't easy.

I'd delete the balance shafts; saves you a trip to the dealer and you will gain free hp ! Make sure you do all of the must dos, rotate bearings cut shaft etc.
