To help silence the problem, try bleeding the tensioner. Start by removing the tensioner from the engine. Next, submerge the tensioner in oil. (Make sure the oil feed hole is facing upwards.) Then, use a large pair of non-marring pliers to actuate the piston several times until no air is noticed escaping the bleed hole. Finally, install the tensioner immediately by hand and take care not to damage the chain ramp.
