RE: CM870 Smoking Issues (02-16-2020 )Submariner Wrote: I ran the overhead again to check it two weeks ago (including injectors). Didn't seem to make a difference. Block valve? As in the cartridge valve in the IFSM right by the fuel return line? Yes the one on the ifsm, and if you have 2 fuel tanks there will be a splitter block valve on the return fuel line. I've had this splitter block valve go bad in the past, resulting in the engine surging. Also, you mention popping. This could be your egr cooler plugged up with soot.
