97 Cummins 5.9 12v smoke under load
Never smoked at all even on cold start, over last 1k miles started to notice small amount light blue smoke, now..
Parked and sat for a week, now when I put the rig under load there is lack of power and lots of light blue and white smoke. Only under load though. While at idle there is light blue smoke , but under load it's is like fog machine at the Disco.
While in neutral I can pull 2k rpm with only light smoke. If I put it in drive then the smoke show starts.
Only have 149k miles just did oil change and filters. Only other clue maybe would be the oil pressure gauge has been acting funky showing higher than usual pressure then suddenly falling back into normal range.
