Hey guys this my first post on this form I have a 97 Expedition 4x4 with 230k miles, 5.4l 2v and e4od trans. I have weird issue when I park the truck after driving for a bit and shut the engine off I get a single pop noise every once awhile. Bit back story I did timing chain guides and cast iron tensioners from melling and hydraulic lash adjusters. Otherwise not affecting performance of the engine just wondering if anyone else ever had this issue before.
