I recently (2 Months ago) purchased a 91' Oldsmobile Calais (Quad 4 engine) from an older couple. The car had 41k miles when I bought it and was in nearly perfect condition considering the age of the car.
I knew at the time of purchase the car would require some work, as it had been sitting unused for long periods of time.. In fact the car only had 1k miles put on it between '00 and '03. In the past few weeks i've noticed the car has gradually developed a rough idle. I've also observed a pretty noticable 'whirring' noise coming from the timing chain cover, on the left side of the engine. It is not noticeable from the interior of the car, but can be heard very clearly with the hood open. I'm wondering if this is normal for this vehicle, or would be indicative of a problem.
Up until this point i've done minor maintenance myself, oil change, front pads & rotors, fuel filter, plugs, just minor stuff, since i have no idea of the past maintenance done to the vehicle. Im curious if anyone here would have any advice for me before i find a tech to service it.
