Hey just picked up a 02 GLE for cheap because it has a couple of issues. There is what sounds like lifter tick coming from the motor, its pretty loud and it increases with rpm. The car has had all of its oil changes on time and was maintained good through out its life, according to the oil change sticker thats on the windshield, the next ones due in roughly 300 miles. The car has a slight miss while sitting still, especially in drive. But it runs SOO good, very powerful and its pretty easy to go 50mph in a 30 zone by mistake, very responsive car... It could be a bad coil or anything since i haven't yet did any diagnosing yet. I searched the net and came across several 3.5 owners with this noise, some say these engines can make this noise when its nearing it next oil change and somepeople suggested switching to thicker oil. Besides the stand still miss, the car runs great, i bought the car knowing its a possibility i might have to toss another motor in it. Friday, im gonna change oil to mobil1 high mileage 10w 30 or 40, install new plugs and coils and go from there, any suggestions?
