I just finished doing a compression check on my TA and found a bad cylinder. Here is the details cylinders 1,3,2,4,6,8 were 210 and cylinder 5 was 100 and cylinder 7 was 180. I did a wet and dry check and cylinder 5 didn't change so I am confused. I am burning a little oil but only under wide open throttle. I am not using any antifreeze either so I don't think it is a head gasket. I have 60,000 miles on the car and have the mods in my sig. What do you guys think?

 

Slightly bent valve maybe?

 

My guess would be head gasket blown between 5 and 7. Wet test eliminates rings, so, it is either head gasket or 2 bent/burnt valves.
