apologize for what must be yet again another ....
So a couple weeks ago I discovered I notice the sound of loose lifters tapping at 1-3k depending on variables.
this am - in quiet mode leaving the house when cold & im thinking hmmm too good to be true. tapping is gone.
So get on the feeder st, and switch from quiet to normal.
tapping is now on
back to quiet, and 2k rattle is 98% gone, only a bit of rattle here and there and quiet,
Back to normal and loud rattle back on.
So guess my workaroud is start in quiet, and once warmed up, switch to normal or whatever.
Thought I'd pass this on as for the life of me I cant see a corelation to exhaust restriction and piston slap/whatever ...
Fairly sure its not injector noise, I'm used to that from GDI cars. So injector pump I see has been suggested as well. Could be something that hasn't been noted before.
Youtubes of 2k rattle are subtle as road noise tends to mask it ... but did hear one where the 2k rattle recorded is what I'm hearing.
So submitted to the academy for evaluation ;)
