Just got back from a 2.5hr trip which included all highway driving and one high power, high speed uphill run. Approaching the garage, noticed the engine is clattering. and clattering significantly. A rhythmic loud ticking, rev-dependent - sounds a LOT like failing rod bearings on a v8 BMW(ask me how I know). Stop the car, put it in neutral, it mostly goes away. Put it back in gear to back into garage and it starts clattering again, just quieter than before. Shut the engine off, wait a few seconds, restart it. No more clatter, quiet as always. Engine has always been relatively quiet(for a 5.0), with no untoward clatter ever. 2013, 113k, 5k oil changes with Castrol 5w20. Checked oil level, it's midway. No codes. Drove around the block after restarting, engine is normal, runs like always. Sure as **** sounded like chains but could it be anything else? Lifters? Will keep an eye on it and try starting it when cold tomorrow. All I've read on the chain issue said it manifests when cold, then goes away(or not). Praying this is a one-off fluke but trying to figure out what it could be. Any thoughts? TIA!
