hello everyone, i'm new to this forum and was wondering if any of you has had a valve clatter sound when the engine is cold. i purchased the fx35 new in 2004 and this is a first for me. i did use a cheap oil filter about a month ago. also it's been cooler here in jersey. by the way, the sound goes away after 10-15 minutes. the filter is a fram, the oil is castrol gtx 5w 30. tia
