Hello. I am looking at a used Ford expedition 05 currently has 130,000 miles on it. The guy is telling me that he cranked it up one day and heard a ticking noise. So he towed it over to his mechanic even though it was drivable. Because he did not want to mess up the vehicle more than what it could possibly be. He said that the mechanic told him that he has low oil pressure. And believes that the oil pump should be changed. The owner of the vehicle found out that same day that his wife was buying a new vehicle for him as a surprise. And tow the car back and decided not to repair the vehicle instead he decided to sell it the truck has been sitting for about two months. Sounds kind of shady to me a little bit but if you have the money to go out and buy a new car guess that’s what you do. Do you think that this could be an oil pump issue or do I need to look out for other issues? He’s going to give me his mechanics phone number because I plan on speaking with the mechanic. I’m going today to listen to the motor. I have seen the vehicle before but the battery was dead so we could not start it. So he charge the battery and later today I will go by and take a look. The inside of the vehicle it’s very clean new tires on the car. He claims that he keeps maintenance on the vehicle. And is not a mechanic so doesn’t know much about vehicles. I was thinking it could possibly be the oil pump switch instead of just the oil pump . As I’ve noticed and read a lot about these vehicles having the oil pump switch problems. Any suggestions would be appreciated. Thanks

Honestly, that is probably the worst year for the Expeditions. It was the first year for the troublesome 3 valve motor. If it had good oil pressure and wasn't ticking already (timing chains and guides...), and no rust, it would be worth about $4,000. So you have to deduct any expected/known repair cost from that. Changing out the timing chains and guides, and a new oil pump (dropping the pan to clean out the oil pump intake screen...) , you will be looking at a $2000 repair bill. I would recommend passing on this Expy. Find a much newer one with a healthy motor, you will be much better off.
I have an '05, as long as it's taken well care of then it's not that bad. In this case, I'd put 1000 bucks on the table and tell him take it or leave it. In the worst case scenario, you're looking at a complete engine rebuild or a reman crate engine. In the best case scenario, you're looking at a new oil pump, and a timing kit including phasers while you're in there anyway. If it has low oil pressure, there's a chance that it has excessive wear elsewhere. A clean and good looking Expy would be worth about 1000 bucks even if the engine is trash, in that case you could even put an upgraded reinforced engine in there which would give less issues than the original one.
If the oil pressure is fine then it's likely broken exhaust manifold bolts or possibly a blown out spark plug. I'd like to hear back where you think the ticking is coming from when you finally get to hear it.

ask for receipts lol... sounds like a bad lie.
He said that the mechanic told him that he has low oil pressure. And believes that the oil pump should be changed.
flat out lie, dude told him the engine needs new bearings. at the best, new tensioners. come on, it's a modular engine. the first things to go are the plastic p.o.s. tensioners. i can guarantee you the oil pump is good, they rarely go bad.
I have seen the vehicle before but the battery was dead so we could not start it
coz the bearings are fried, you need to hook up like two batteries to even get it to start. starter also needs attention as the connections are probably toast.
He claims that he keeps maintenance on the vehicle. And is not a mechanic so doesn’t know much about vehicles.
that's the most common thing to say when someone knows a problem "im no mechanic, i know jack about cars". check the dipstick, prepared to be amazed when you see pieces of grinded bearings on the dipstick. well either that, or they're about to go. **** you not, the oil pickup tube is filled with plastic parts - being the tensioner guides.
if it was a minor issue, he'd just dump a bunch of riselone "motor magic", that red crap, and sell it to you for the full price. unless you got time to screw around for a month or two excluding the time it takes to buy parts for it, better off going to a dealership to buy a car, no offense. at least there you can get 30 days of warranty or whatever the hell. trust me on this, i intentionally bought a suv w a 4.6 with same issue, was planning on replacing entire engine, just replaced two pistons, crank, tensioners, and a few valve lash adjusters, the same motor AND oil pump is still outliving the first oem build. the reason for this is you HAVE TO change your oil
Well, the modular engines do have a weak oil pump with a design flaw (weak back plate). Thing is, by the time the oil pump is toast, the rest of the engine is usually toast as well. Might even be too bad to even be possible to rebuild. There are improved reinforced oil pumps available, both with standard pressure and increased pressure.

It's true, depending on the amount of debris that got inside. The pump I had on my 4.6 mountaineer still works very well past 250k miles, it was rebuilt around 125k miles or so. But never hurts to check it.
