6.0 White smoke, Maybe EGR cooler? Input please before ordering new cooler.
My Father in-law has a 2004 Harley F-350. Rig has 78k on it, and is treated very nice. He idles it 15 min before driving it every time, but shuts her down immediately when he gets to his destination. That's all i can think of as far as info needed.
Now here is the problem. The truck spits white smoke. Not alot. Starts fine, idles fine, has 100% power. But after 10 min when she starts to warm up, the white smoke starts. Does not do it under WOT, or when stopped, only when coasting down from speed, and under steady throttle. the tailpipe is full of wet soot.
So after searching here i found that the EGR coolers on these vehicles seem to be troublesome. So in order to ensure that $400 on a new unit from bulletproofdiesel.com is well spent, we pulled the EGR to verify whether or not it was wet. The tip of the plunger seemed to be a little muddy, but the unit as a whole was not soaked. Same with the hole in which it came out of. It was pretty dry as far as i can tell. But i did notice some coolant in the valley, but could not see where it was coming from w/o pulling the turbo off.
My questions to you all (sorry of uber long post):
1. Does this sound like an EGR cooler?
2. What does it only exhibit this some under certain load conditions? I assumed it would be at all times.
3. Is there anything else we can check easily enough to determine the problem w/o putting her out of service for a few days? (Daily driver + plow truck)
If any more information is needed, please let me know and i can get it to you. Thanks!
