olds 3.1 question
 

okay somebody please help my 93 cultass 3.1 multiport is making a small pop noise once u put it in any gear it will stop and it usually happens when it has sat for a long period of time after it warms up it also goes away i think maybe exaust manfold but dont now

moved to its own thread we dont bring up old threads unless you have a specific question for the original poster of the thread

a fast pop could be exhaust manifold a squirt bottle with soapy water will find leaks spray the joints and look for bubbles

A pop? When put into gear would make me think something is loose or worn out. I would look at the motor or trans mount.

My achieva made the same noise and it was the transmission mount was past do for replacement, also it could be your lower torque strut mount on the bottom passenger side of the motor. I had to replace both of them and my noise went away. Also the torque strut mount it pretty easy to replace if you know what you are doing, but that mount is very small and only can be accessed by pulling the passenger side tire and the removing the plastic shielding that covers up the harmonic balancer and a few other things. The transmission it one that will take you awhile to do because it is a two person job to remove the bracket that the transmission mount attaches to. But for me the noise you were describing was the mounts but it could be something different on your car. I thought I would just give my helpful advice.
