- The distributor shaft looks just fine to me. How am I supposed to find out
- if it is worn. I asked a GM mechanic and he said he could not find any problem.
-
- There are no gasoline fumes in the egine compartment.
- I doubt that the fuel recovery system is leaking. I am quite sensitive
- to the smell of gasoline.
-
- The PCV valve has been replaced earlier. I do not see a connection with the explosion.
-
- I think the rotor broke apart due to centrifugal force. It was probably defective.
- I think that before it broke up, it was warped and the friction set the cap on fire.
- But this diagnosis has too many holes.

- That may be. Why do you say this?

- Thanks for your reply.
