Purchasing My First 6.4l

Found a nice looking 2008 lariat 6.4 on a used car lot... here is what I know:
163k miles
Previous owner was a farmer
Carfax comes back clean... actually has alot of services on record
egr/dpf deleted, found a dpf+r tuner rolling around under the back seat
No lights on dash
Starts up just like every other 6.4 i ever heard... and it had been sitting there for a week untouched
Air bags in the rear
B+W flippable gooseneck ball
18k asking price, but its been sitting there a while, I plan to haggle
Vin if it helps... 1FTSX21R58EA50226

Most of the miles I put on this truck will be with 3-7k hooked up to it.
What should I look at on this truck before i pull the trigger? Is there any reliability concerns with this truck, seeing as its deleted? Also, what should I do on the test drive to ensure its in working order?
Thank you in advance.

I have no actual experience with these trucks. I have friend that had one and he absolutely loved it and hauled with it a lot but it was in the shop a lot and last year he said the motor went kaputt, no details but he said it's screwed and he's thinking of swapping a 12 valve in.
I had always thought that the 6.4 was worse than the 6.0 but like I said I have no experience with either of those two engines. I skipped from the 7.3 to the 6.7 because I had been scared off by all of the stories about these motors.

If and if it was taken care of, then there maybe some use left. Max 5K on the oil changes, check them out. The 6.4 can suffer from valve train wear.

the radiator for any leaks are the drivers side wheel well.

I would highly suggest towing with it up the biggest hill at full throttle and see how it does. The VCV on the HPFP can be bad on occasion.

Check for regular fuel filter changes. All filters should always be OEM.

You need something to monitor the vitals. You cannot have a deleted truck and nothing to monitor with.

You should never buy anything from a farmer. Never. Also you should do some research into the 6.4. It's a 100,000 mile engine at best. Nobody wants these things.

If you're towing less than 10k you would be just fine with a gasser. Gas is cheap and maintenance is cheap. Diesel maintenance is crazy expensive.

Look for a gasser without a triton. Every triton will need spark plugs and cam phasers right off the bat and that can cost $1,500+.

Just talked to a guy with an '09 6.4 yesterday. He's currently on engine #3 which has a bent exhaust valve, massive blowby (drips/burns a gallon of oil a week), and the truck has 150K miles. He bought it at 130K with it's 2nd engine and just had both turbos replaced (chasing the oil consumption problem) This current engine replacement is estimated to cost $13K (includes 30 hours labor), and the $5K engine warranty he bought just expired. Need I say more? Read here: https://en.wikipedia.org/wiki/Ford_P...4_Power_Stroke

Would a trip to a third party diesel mechanic to check the whole thing over top to bottom be worth the time and cash?

Bro, read the wiki that guy linked. It's trash and Ford should buy back every single one.

"The 6.4L Power Stroke was introduced for the 2008 model year, known as the Slug."

I was going to get a gasser... until the single digits fuel mileage scared me enough to turn the other way
Also, why should I not purchase a used vehicle from a farmer? Would it indicate being abuse even though its been maintained?

Gas is always cheaper than diesel though. Diesel was nuts when Obama was in office. I expect it to rise again when "the big man" takes over. My 5.4 gets 10 mpg unloaded but gas is only $1.75 a gallon here. It was $1.25 for a short time last year. Diesel is like $2.30 here.

Farmers beat the hell out of their equipment. They never take anything to a garage either. They do all the work they can themselves, even if they don't know what they're doing.

Farmers never sell anything either. They use equipment until it breaks and they will park it out back. If a farmer is selling something he has a good reason. I'm not trying to tear farmers down. They're hard on things though.

true, I am aware how bad equipment can be used... I do work for the county after all haha
considering the interior is in such good shape, as well as the exterior, I would reckon it isn't too terribly abused... besides I would just abuse it myself because I will be working it.
Anyway, the guy at the used car lot says it was a trade in, the guy went to a newer model. I'd go so far as to say there's nothing mechanically wrong with it... but I cannot be sure, which is why I would have it checked by a diesel mechanic.

Have you googled "6.4 powerstroke problems?" I ain't joking, it's a lemon dude. They only produced it for 3 years for a reason.
