99 S10 overheating/losing coolant from block

Hello all,

Haven't posted in a while, I have a 99 S10 4.3 2wd. Last week on a 5-6 mile drive it overheated, and it turns out the coolant was somehow almost a gallon low! I topped it off and all was well for nearly a week. This weekend I was driving and suddenly could smell a strong coolant odor. The temp gauge began to spike and when i pulled over and popped the hood it was clear the coolant was finding its way out but not through the overflow or radiator. When it cooled down and I added water/coolant I could see the coolant coming from the block or near the block. Also, when I let it run for a few minutes i could see the fluid "spraying" out from what appears to be near the pass. side valve cover maybe near the intake manifold...The oil looks good, so I'm not sure it's the head gasket. Not sure where to go with this. I can't really afford to get it to a shop at the moment. Is this the end of the road for my S10?

Thanks,

Leo
