Need some help figuring this one out! Here's the short of it: I recently changed the water pump gasket, then proceeded to be a dumbass and not verify that I had completely filled the engine with coolant. I went driving around and soon enough the engine was pinging a little bit... then all of a sudden felt and ran like I had disconnected a couple plug wires. I limped it back home, about 5 miles or so and put it back in the garage. I checked the oil, still black since I really need to change it. Coolant is still transparent green. So I went and bought a compression checker at Shucks and the 5-8 cylinders (drivers side) are all 150psi. But when I tested the other side #2 was at 40psi. Thus, my question is: did I pop a hole in the piston or break the head gasket?
Yes, I am a dumbass.
