Alright, I bypassed the FDC after changing the oil. I had put 12 gallons of fuel in the other night before all this. I got the truck fired back up awhile ago and let it idle looking for leaks. It idled roughly 5 minutes and then it's sucked the tank dry.
My question now is this: If the FDC was causing my fuel in oil issue, is it possible that I pumped 10 gallons or so into the crankcase before I bypassed it?
Keep in mind that I drove it maybe 500 yards or so just above idle before I bypassed the FDC. I guess I'm wondering how much fuel can flow into the crankcase if the FDC is problematic. Is it capable of just dumping fuel into the crankcase or is it only likely that it will trickle in there over time?
If it's capable of just dumping fuel in there then I will feel safe refueling the truck and running it awhile. If it's only possible that it will trickle in then I'd say I have a major malfunction elsewhere.
The other thing is, do I need to adjust my fuel delivery down because of this bypass? At the moment I'm making almost no black smoke anywhere in the rpm range. I have a little blue smoke above 1500 but that's about it.
