This noise is not from the filter - I have tried 3 different brands including the OEM, all with the same result. I always use 5w-30 syn oil year round.
I believe this noise is standard textbook piston slap - just google the term to get a definition, for those that don't know.
I am only getting the noise when the temp is cold or below 5c - the colder the outside temp the louder the noise. It will go away after 10-20 minutes of driving.
I have experienced piston slap on other engines however, this 08 versa is by far the worst/loudest I have ever herd.
I have 62,000kms on the engine - many people have reported issues and noises from as early as 11,000kms around the internet - so I guess it is something us Nissan drivers will have to get used to.
thanks for the input...

I`m going to respectfully disagree here. Our 09 1.8L versa is quiet. Although it is still at a young age of 13K, I`ve never experienced start up knock or valve train noises that are normal in this car as of yet. I have used OEM, Wix, Purolator, and Hastings oil filters, all good. I do have a few Fram on the shelf, these will be fine IF you use them for the drain interval they were meant for. I`m am currently waiting to try filters made by MANN.
I have to respectfully say that the 2.5L in my Altima has to be the loudest I`ve heard to date. and I cant help but think what a POS and it is nerve racking. I do believe it is piston slap as in loose clearance or collapsed skirt from past experiences rebuilding engines. sounds like Forged pistons set loose. My Yamaha 1300 2 stroke is quieter. I am not certain what it is as the car only has 15K on it. The hollow slap sound is def a lot louder when the temps drop into the 20s and eventually dies down some as the motor warms, but the noise is always there... always there...
someone mentioned that synthetics produce louder noises. mmm I don`t think soo, I`ve been using synthetics for years, mostly Amsoil, but have mobil one currently in the car...
here is a tip: Motocraft 5W30 oil is a synth blend and very good at a decent price when found at walmart.
