90 Z-TT: runs fine, no smoke ect. but during a boost leak test my exhaust valve covers seem to be bleeding off the air. is there any performance downfalls to them leaking? slow spool or rich/lean? could it mean bigger issues? valves/rings, ect...? How to confirm/should i worry about fixing them until its convenient?
