Pop Pop Pop
1981 911sc
Pcar runs very well. Except....... in mornings when I first start up there is a pop pop popping sound coming from the airbox. I don't have a popff valve. doen't happen after car is running. What would i look at to see what is causing this? Tx!john |

before you do anything else....get a Pop-off valve ASAP.
A blown air box will cost you over 1 grand to replace....ask me how I know..

hey mr. flat, i dont know too much about these 911 motors, all i know is that they are 2 cycle motors...and that's about it.
 just get rid of the internal pressure buildup and your popping will go away. this may sound obvious, but the sooner you understand the phenomena and source of the problem, the sooner you will arrive to the solution...good luck
