2004 9-5 with engine knock
http://youtu.be/5OngmpWncaU
My name is Dan and am a newbie to this forum but not to Saabs.
I bought a 2004 9-5 Arc station wagon auto with 114k miles. I bought it with a known 'knocking noise' from engine compartment.
Vehicle was owned by a meticulous one owner and kept the car in great shape with mobile 1 oil changes.
I'm hoping to diagnose and repair( best case )or replace engine(worst case).
Description of knocking noise:
-dies down with higher engine RPM
-dies down when HVAC system is switched to off
-no oil leak or SES light
-seems to be coming form oil pan area(using the screw driver to ear trick)
Next step:
-drop oil pan to see if a rod/bearing is loose
Any one on forum have any thoughts/experience on this noise. possible sources and solutions?
Thanks for your input
