6.2 intermittent valve train ticking noise at start up ??????????????

[Deleted member 17706]

Okay, I am curious what this noise is:

I am not talking about the normal ticking that you hear from the lifters. The rattle in the video is much more obnoxious than any lifter ticking noise.

Thoughts?

Def coming from valve train...my money would go to new tensioners first (and throw new chain and guides while in there)
Also maybe oil pump starting to fail
Outside chance it’s worn out phasers (caused by failing pump)

Yea, I thought so too. A trusted mechanic that I know thought the same thing. I am disappointed to say the least. I have went above and beyond maintaining the truck. I have been from Florida to Prudhoe bay and lots of places in-between. LOL I thought the Gen 2 was the only one to have engine problems Decisions decisions.......

Not sure if this has been posted before. Here's a video regarding what you're hearing from a Ford Tech (FordTechMakuloco on youtube) that specializes in these engines. He is referencing the 5.4 but the 6.2 is the same basic engine.

The 6.2 is actually a completely different engine architecture than a 4.6/5.4/6.8. The valvetrain uses shaft mounted rocker arms with hydraulic lash adjusters; no roller follower. I have seen the lash adjusters stick within the rocker arms, which causes a nasty tapping noise.

Good to know, thanks for the info. Was the 6.2 used in other vehicles or only the Raptor? Kinda surprised to here that it's a different engine.

It was designed to replace the 5.4 as the base engine in the Super Duty. Hence the physical size and weight. The 6.2 was the only truck engine available at the time above the 5.4, so they made it an option in the F-150 in 2011. It’s still used in the Super Duty as of ‘22 as the standard engine. The 7.3 and 6.7 are optional upgrades.

FORD 6.2L V-8​

FORD 6.2L ENGINE SPECS, INFORMATION​

Ford's 6.2L V-8 went into production for the 2010 model year as a high performance option for the Ford F-150 SVT Raptor. It was briefly marketed as the "Boss 6.2L", being launched as the latest variant in Ford's Boss engine family. The name is largely misleading and the "Boss" namesake was primarily used internally in the same manner that the latest generation 5.0L finished development with the "Coyote" designation. The 6.2L V-8 replaced the 6.8L Triton V-10 in the Ford Super Duty (F-250, F-350 models) for the 2011 model year. As is normal of trucks with heavier capabilities, the Super Duty version was slightly detuned. The engine was also introduced to the F-150 lineup for 2011, but was ultimately retired following the 2014 model year.

Certain features, such as the engine's large bore and small stroke, were reportedly inspired by Ford's motorsport heritage. The 6.2L V-8 employs two spark plugs per cylinder (16 total for the engine) in order to maximize combustion efficiency, which directly impacts performance, fuel economy, and emissions. Like all modern Ford engines, the 6.2L was subjected to rigorous durability and endurance testing during development, which included bench testing engines at peak power for non-stop 500 hour intervals and subjecting them to high load, real-world driving tests lasting 1000+ hours. For 2017, the redesigned for Super Duty pickups and chassis cab trucks received an upgraded 6.2L V-8 as the standard engine, with torque being increased from 405 to 430 lb-ft.

Internally during development it was known as the boss 379…

Any way to fix/clean this? Mine used to only do it briefly at start, but now it’s longer and longer. 2012 with 165k miles.
