Okay, so I have a new random noise to worry about.
I've a 24v 4.2 manual, 180,000 miles, no smoke, runs fine, etc... but has just started making a slight metallic tinkling noise from somewhere around the engine - almost like a light chain rattling or a heat shield vibrating. It doesn't do it when the engine is absolutely cold first thing on start up, BTW. We've looked all around the exhaust system and can't find anything loose, so we're kind of stumped, though if pushed I would say its louder around the down pipe/turbo area maybe.
Only thing we have done different recently BTW was an oil and filter change - not sure what it was running before, but its got GTX 10W/40 in it now - could it be related or just a coincidence?!?
Any ideas gratefully appreciated, as we're going to be going on hols in the truck soon and I'm not sure whether to be concerned about this or not!?!
