I did a compression test to determine if I had an exhaust valve stuck open. Results are a bit troubling, but didn't give me a clear answer to the noise and burned oil smells... though that does remind me to check the PCV hose on the oil trap.

#1 - 115
#2 - 130
#3 - 130
#4 - 160
#5 - 150

#1 is obviously a problem. #4 seems kinda high as well.

For reference, here's the head and valves right when I removed it.

You can see where the head gasket had failed on #3
