Are the rod knock indications of bad a bearing a progressive noise? What I mean is, does it start quietly and intermittent then go to the loud knocking sounds over time.
When my car is cold and I start up I hear a bit of a knocking/slapping sound till the car warms up. I start the car and wait a bit till it goes away because I surmise that it is the oil getting circulated not actually a bad bearing.
Any thoughts? My car is a 02 wrx wagon
