strateman Posted April 22, 2009 Share Posted April 22, 2009 I've got an '04 250. While pulling about 9k worth of 5th wheel I get some sputtering and huges clouds of black smoke. Had the truck in the shop a few weeks ago for a bed plate leak, just happened to think about the oil servicing thing and decided to change the oil it was definately overserviced, like 16+ qts. I haven't gotten a fuel sample sent off yet but it did not smell like fuel. Could too much oil cause my problem and would it only happen under load? No CEL engine light, I'll run in to town this evening and see if I have any codes. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted April 22, 2009 Share Posted April 22, 2009 Without more information, we're kind of shooting in the dark. I'd suggest the basics- KOEO, KOER, DTC tests, fuel pressure test under load, and scan data observation while the problem is occurring. Remember you have to do 4 things to get all of the trouble codes out of a Powerstroke- KOER, KOEO, buzz test, and continuous codes. If you just hook up and pull codes you're not getting them all. Your problem sounds EGR or turbo related, but it's too early to tell. You say "run into town"- what kind of scan tool do they have in town? The Ford diagnostic sheets are worth gold in a case like this, and they are contained in the Coffee Table Books listed to your left. Find the appropriate diag sheet and follow it closely, it will identify the problem correctly 95% of the time. If you can't find the diag sheet, e-mail me and I'll sent it to you. Good Luck!
