Rising Sun Posted July 16, 2017 Share Posted July 16, 2017 I am a new owner of a 1998 RD688S and I just recently encountered some problems and I am seeking help. 1. Just had the #1 plunger replaced because there was no fuel going through that fuel line and once I had that done, I am now seeing white smoke out of my stack, and the turbo is leaking. Can someone offer me some suggestions 2. Also, I just added a gallon of oil and my oil pressure gauge is at 55psi. Do I need to let it warm up to get back to normal?
