engine back fire under deceleration
I drove Camaro today, No problems oil pressure good, there's a long down hill part. I let off the gas pedal and it started rumbling and backfiring allot.
got it home and the left side lifters extra loud. I'll pull apart and inspect rockers and and springs soon, Any ideas would help

When you lift from the throttle above a certain RPM, in most engines, there should be a 100% fuel cut. The engine is supposed to coast "engine brake" with air only (no gas). If, during this time, you are getting any kind of ignition (explosion) pops and backfires, that is a diagnostic clue that fuel is entering the cylinder somewhere (leaking injector).
