    Thread: timing belt then blow up????

      i just did a timing belt and head gasket on a 2.8l avant.
      it ran before i did this.
      i got it all back together today and cleared all the fault codes. none popped back up.
      i did a TBA and it went through well and it still idled funny and no throttle response after.
      i was holding the gas to the floor and it started to idle better. then there was a loud bang twice and then it just jumped up to red line and then shut off...

      any input please help.

      I agree, things do not sound good. I'm currently repairing a 30V V6 that had the timing off a notch and it bent two intake valves (cyl1&4). Those pistons are dished and virtually no clearance.
      Good luck.

      so if valves are bent but not broken, replacing the valves will solve the problem?

      I mean, the piston looks good in my car, I was wondering if there could be some damage beyond what is visible in such case.
