Hello. New chain tensioner installed (124k miles), timing is spot on after verifying. The new tensioner has caused a very brief chain rattle for less than a second after starting when car has sat for a few days. Any ideas? Mercedes OE tensioner. Car has been serviced every 5k miles. Didn't seem to rattle prior to install. Does not do it when warm, or if the car is driven routinely.

Any thoughts? Thanks.
