2024 Ranger 2.7L knock/ticking

[evance]

I’m writing to share my experience with a knocking sound coming from my 24’ Ranger with a 2.7L engine, which has 1200 miles on it. It started making this knocking sound around 150 miles, and was not affected when I changed the engine oil at 1000 miles. The knocking sound seems to follow a RPM increase to about 1500 RPM, but it’s unable to be heard primarily after that due to overall engine noise. On cold starts it doesn’t make any unusual noises. No diesel like chatter similar to the failing cam phasers of the 3.5 EB and 3.0 EB. I’ve attempted to chase the sound with a stethoscope. I’ve narrowed it down to bank 1 exhaust cam and the volume is the same from the front of the engine to the rear.

I’ve taken it to the dealer, and they said it’s not normal, but they don’t know what it is. They’ve contacted the Ford Helpdesk, but they don’t know either but would let the dealer know what engineering says. They still have not heard from Corp Ford. They told me to keep driving it and they’ll call me with any news. They don’t seem to have an issue with me continuing to drive it yet mentioned it might just get an engine replacement.

Has anyone else experienced this noise or had a similar experience?

That is not wright its not a consistent sound. It keeps going away and coming back. Does it go away after its warmed up.

It does not go away once it’s warmed up. If anything it gets louder.

yeah they will have to replace it probably, yours is the first I think on here with a 2.7 making that kind of noise. I hate it happens but it does yours may be first but I am sure not the last. The 2.7 have been great motors but Failures happen in any motor.

Like mentioned above it is not constant. Sounds like a chain slapping or something like that.

Update- it’s getting louder. Ford dealership says keep driving it. I’m at 3.8k miles. I’m supposed to take it back again once it hits 5k miles. Back at 2k mile mark, Dealership claims they pulled the bank 1 valve cover, leak down test, scoped the cylinders, changed my oil, did an oil sample per Ford Corp. Looking at the valve cover and everything attached to it, especially the bolt heads, I would wager a large amount they didn’t actually touch anything or even change my oil. They seem to forget that everyone has FordPass and can see gps location. It was in the same parking spot for a week. When I called for an update at the week mark, they pulled it into the service center for maybe 15-20 minutes and called me saying that they had done all that work. My sister has a 2.7L in her Bronco and it is so much quieter. No knocking. Bummer.

Sorry to hear that you're still having trouble with your engine and also that you're that your dealer isn't trustworthy. But thank you for sharing the update with us.

Time to start using the term "Lemon Law" with your dealer AND Ford. That should motivate them to get their collective asses moving.

YOU should also be in direct contact with Ford and have a complaint open with them, not work this through only the dealer. Why? Your dealer doesn't really care what happens, they get to invoice Ford for warranty dollars every time they touch your truck.

I have an interesting development regarding the knocking. I changed two variables at once—which I know isn’t ideal for troubleshooting—but I wanted to try something. I decided to change the oil myself again and collect multiple oil samples. This was done at 4,000 miles since the dealership’s supposed oil change.

I had used Valvoline Extended Protection 5W-30 during the 1,000-mile oil change, but the noise didn’t change. When I first got the car, the oil was slightly overfilled from the factory. During that early change, I filled it right up to the max line. After the dealership’s oil change at 1,900 miles, the oil level ended up about 4mm over the max line.

While listening and graphing with a stethoscope, the knocking was loudest at the oil-to-coolant exchanger mounted to Bank 1’s head. I could also hear it in the Bank 1 turbo oil feed line. Interestingly, it wasn’t audible at the banjo bolts—just smack in the center of the line. That made me wonder if it could be something like water hammer or hydraulic shock, similar to what you might hear in household plumbing.

This time, I switched to Pennzoil Ultra Platinum 5W-30, which meets Ford’s specifications for these engines. I’ve read multiple reports of it quieting valvetrain noise in other engines. I also kept the oil level just below the max line—about ¾ full. After the oil change, the knocking persisted for about 10–15 miles before gradually going quiet.

Whether this engine is especially sensitive to overfilling or the Pennzoil has some kind of magic in it, the knocking is now gone about 95% of the time. It still occasionally returns on short trips (10–15 minutes), but even then, it’s much quieter and becoming less frequent over time. I haven’t received the oil analysis report yet, but I saved three extra samples in case Ford wants them later.

Since all this started, my sister bought a new Bronco with the 2.7L engine. I could’ve sworn I heard the same knocking in hers during the first 1,000 miles—but maybe I’m just a little crazy from chasing my own issue. Her oil level was, and still is, perfect, and she’s also running Pennzoil Ultra Platinum.

I’ll update this if anything changes. Hopefully it’s not just the calm before the storm—but if things stay like this, I’m satisfied.

I would not be satisfied, the knocking that you've been hearing is damage of some type occurring in the engine, not something you want to be playing with in future.
