I have a 2009 F150 4.6l 3v with 356k miles on it. I bought it new and changed the oil with Mobil1 synthetic 5-20 every 6k miles. No major problems engine doesn’t leak or burn oil. Replaced the alternator and ball joints other than normal maintenance nothing else

[ryanturgeau]

I have a 2010 F150 4.6 3V at 180k I replaced all timing components and installed a high volume oil pump. It has 250k now still running great. 5w30 in these engines are a must imo.

I currently own a 2003 Grand Marquis with the 4.6, best engine I've owned. It currently has 167k miles, just blown it's first plug last week, calvan kit saved it, not a hard job at all, took 30 mins. Only engine issues I've had was the common intake coolant leak (new intake needed) and a thermostat. I'm never selling this car

All of my vehicles are 4.6L. I have a 1997 Expedition with 220k I have a 2008 Crown Vic p71 with 150k and a 1998 Mustang GT project. I trust the engines with my life. They last forever idle smooth and are easy to work on.

I have a 2008 Mustang with the 3v. This is an extremely reliable engine, like Toyota level reliable, with one caveat, you have to do the recommended maintenance/oil changes. As long as you do that, there’s really no issue with timing/phasers or any other part of the engine.

Im a chevy guy. But bought a 06 xlt 4wd f150 4.6 2v that was banged up on right front and had a stolen salvage title to boot. 1300 bucks. A shit ton of miles also. So i knew it had been rawhided. I rebuilt suspension. Basically went thru a thorough tune up. Replaced entire ac system. Its been 3 yrs and commute 100 miles a day and drive with purpose myself. Ive been really impressed by that sucker. The smetric transmision is what ive been disappointed by. Its still a helluva spunky truck tho

[LockmanU]

I have a 2005 Ford E150 cargo van with over 333, 000 miles on it, I haven't had any trouble with the engine. I add a 1 quart of oil between oil changes. Oil gets changed 5, 000. I do most all my own service work.

The 4.6 v8 2valve engine is the best engine ford made in a long

[dannylane]

I’ve got a 98 rcsb 4x4 with the 2valve 4.6l V8, truck has been flawless for over 14 years of ownership, just ball joints and regular maintenance stuff. A lot of ppl dog on these trucks, but the 4.6 2valve is an absolute work horse! I see them out on the roads all the time. Still putting in work. I personally love my truck, it’s has 385k on the clock, still runs great.

[martycann]

Got a 4.6 2v in my 2001 Mustang GT, got a 4.6 3v in my 2010 Explorer Sport Trac Adrenalin, got a 4.6 3v in my 2010 Eddie Baurer Explorer. I must say the 4.6 has been super reliable. I have never been stranded, or had one issue with any of them. Regular maintenance, oil changes go a long ways. This engine does not make me miss my 5.0's from the 80-90s.

[scorpio]

My daily is a 2010 F150 4.6L 2V. It only has 55, 000 miles on it and I plan to keep it for a long time. This particular engine is one of the most reliable V8s ever made!

[infinityjif]

I guess I've been extremely lucky because I never had timing chain issues or oil pump failures in none of the six 4.6L and one 5.4L engines I've owned. I did have to replace 1 intake manifold.

[fredricgreenblott]

I’ve got a 2004 Grand Marquis. Love the 4.6L and I’m glad to have the 04 model, which is when Ford began fixing some of the more common problems like intake manifold cracks, etc. Approaching 127k miles and it runs like clockwork. I drive it a LOT, around 20, 000 miles a year. I put Castrol Edge high-mileage 5W20 in there and just had the coolant and rear differential flushed. Here’s to another 100k miles!

I had a 4.6 in a 95 Crown Vic. Single exhaust 190 hp car. Though I had to trade the car for the dreaded minivan, it was a good running motor car. I never had any engine problems. It would yield 28-33 mpg on the highway loaded down with family and luggage.

[LouJustlou]

My 2000 4.6 2V has 299, 000 miles and still runs great. No timing chain rattle yet. Regular oil changes and routine fluid service. Automatic transmission still alive too.

[markboyce]

I have a 2004 F150 STX with the 4.6 engine 2 valve, after replacing the spark plugs, one pop out, EZ fix, with 244000 miles on it, runs perfect, does not burn no oil and still have plenty of pep, everything orginal including the alternator, runs good and strong.

[russwentz]

Thank you for passing on these important factors. I've been wanting to do some much needed planned maintenance on my 2005 E150 bread N butter work truck. Greatly appreciated.

I have a 98 F150 4x4 that's badged 4.6 Triton V8 on each front fender. So I'm not sure what your talking about when you say the 4.6 was never identified as the Triton. It's also been absolutely reliable for the 311, xxx miles I've put on it since new. It had 8 miles on it when I bought it new in 98. I've not experienced the spark plug issue or any other problem . I change the Full Synthetic 10w-30 engine oil every 6000 religiously and have the transmission serviced every 15, 000 miles religiously as well. It's been a fantastic truck. A little more power would have been nice but it's running as good as it did new

I’ve been a professional technician for 30 years and I pretty much hate all brands these days but the 4.6 2 valve was a major leap forward for Ford’s small block technology. With proper maintenance they were fully capable of running great for hundreds of thousands of miles. I can’t speak for other states but back when our state’s Highway Patrol used Crown Victorias exclusively the idle hours alone were staggering. That’s not even taking in consideration the number of miles on them. They did it on regular bulk 5W20 too. After all that cab companies couldn’t wait to buy them at auction and then they would put in tons more miles in cab service. I’ve worked on my share of 5.4 Triton trucks and they were definitely more problematic but I have still seen a lot of them in fleets with 350-400K miles. I’m being honest. I prefer the more simplistic design of the LS platform but I can’t be critical of the 4.6 2-valve after seeing so many of them run great for hundreds of thousands of miles. Maybe I have been lucky but I’ve never had to fix a 4.6 2-valve for spitting a spark plug out. I’ve done 5.4 Tritons over the years though.

[johnandersonjjr]

I’m driving an 11 towncar with 470, 000 miles on it .I saw the maintenance records before I bought it and saw no major repairs.The oil light did start coming on a few thousand miles ago . I started using 10 w30 instead of 5w20 and I haven’t seen it light up since
