Pulled my 5.4 out of my 1999 sd f250! What next?
Long story short, driving after 2 hours oil pressure dropped! Oil temp light came on! Pulled over after 3 miles, soon as I stopped engine died, after 2 hours it started up and drove on the trailer,
I decided instead of changing the oil pump with the motor in the truck, I would just pull the motor and go thru and fix what I can or rebuild what I can on the motor! I got it pulled out within 11 hours! First time ever pulling a motor!
my question is what should I do to the motor while I have it out? I’ve never done any motor work but I’m mechanically inclined and can probably rebuild it myself. Just not sure what to start with. Any advice?
motor has 220,000 miles on it!
Just a pic I snapped while pulling the motor.
After removing the intake from the motor!
This is the motor I pulled!

Did you test the oil pressure first to see if it actually had low oil pressure? It could of been just a bad oil pressure sending unit.
Once out I would highly suggest you take the oil pan off and see if the bearings are toast, it's rare for one of these engines oil pump to fail, I've never seen personally.
IMO at that mileage I would just rebuild it but if your short on $$ then read below.
If all checks out pressure wash the engine making sure you cover the intake runners.
Buy a Cloyes timing kit to do the timing chains and guides. Buy a master engine reseal kit and remove your heads and take them to a machine shop to have them freshen up.
If you have broken exhaust studs now is the perfect time to take them out.
Even with a junk yard engine I would do the stuff I posted above.

Ok
I will definitely do that! I got a quote from a guy today for a 5.4 with 115k miles for 850 bucks, 6 month warranty, I may go ahead and buy that for a backup if I can’t fix mine.
also I did not check oil pressure, because I was sure the oil pump went out, I don’t know a bunch about how it works so please correct me if I’m wrong. (I probably am) but when my oil pressure dropped and the oil temp light came on, my truck died when I got pulled over and when it started up and drove on the trailer it had a bad knock, almost as if it didn’t get any oil up in the top of the motor? Also after setting 2 days I started it up and drove it into the shop and it had a bad knock, I’m almost certain the oil pump is bad. I watched and read a bunch of you tube and forums that says the 5.4 oil pump is a flawed design because it restricts the oil flow, but milling makes one that allows more oil to be pumped,
if it were just the sending unit, my motor should have never died or started a bad knock right?
