2005 Cadillac SRX Engine Tick
Recently, the SRX ran low on oil (but no Oil Pressure light). First and only time. I now have a constant tick in the engine. At first I thought it was a rod knock, but it doesn't have the symptoms, i.e. no rough idle, no change of sound on acceleration or deceleration, and not very loud. As best as I can determine 1)it's not top end noise, 2) can't be heard from inside the car, 3) it does get a bit louder after the engine heats up, 4) the engine runs fine, 5) 1 for 1 with engine speed, and 6) tick across the rpm range. Engine info: 4.6L Northstar, 133K miles, Oil recent change and added GB MOA with some change noted.
Any suggestions before a motor replacement?
