2023! 2500 gasser here…Bought my truck with this same issue.. and the POS dealer knew it .. so he had my truck already running when I went to get in .. Anywho..0il rapidly rushing through veins somewhere in the system does make sense.. the [noise] hasn’t got any worse… I would like to find out what set of veins so maybe I can prime some how to get rid of the start up issues… ok 10-8
