1995 Nissan Altima 4 cyl Front Wheel Drive Automatic 117K miles
For the last 2 or 3 months I have had a strange rattling/whining noise coming from the front of my car. When the mechanics check, they say it's coming from the location of the oil pump/timing chain. Also as I am driving, I hear this whining noise in the gas pedal. All of this calms down (not completely) after the car is warmed up. I have had just about everything replaced: chain (and all the accessories with it), oil pump, timing cover, water pump, etc. Except for the engine itself, all the parts under the hood are new.
The latest is that others have listened and thought the noise could be the idler pulley. I did the wd-40 test, and the noise disappeared and came back. When the mechanic took the belts off (left the pulley on), the noise was still there. I checked again with others and they suggested the noise was coming from the timing chain sprocket. Someone else suggested the timing chain guide. Took back to the mechanic and he said that when he had the car before he checked all that. Everything was fine. He even replaced the bearing for the sprocket.
It has now been about 6 months with this noise and still no relief! PLEASE! Can someone help me figure out this awful noise?
