Ooooh ! i can feel the pain
Sorry to see that!
Now i am totally paranoid to any sound i can hear while driving. She's all i got

 

Just keep a close eye on the egt's. 03's are prone to valve seat problems.When you get them hot there prone to dropping an exhaust valve. The sound that it makes before it fails is kinda a hollow tic in the exhaust. If you start hearing a hollow tic in the exhaust you need to have the head checked to see if it needs to be repaired or replaced.
Sorry for stirring things up.
See ya,
Topper
