I have a 2014 Ford F150 FX2 with remaned 5.0L crate engine. On startup the engine has a tick at both hot and cold condition. Ford says the tick is normal for 5.0L engines and the noise is a result of oil shearing off the journals. The noise is more prevalent at the oil pan, but can be heard in the fender wells and under the hood. My oil pressure is 17psig hot at idle and 75 psig above 1700 rpm hot. Using Valvoline 5w30 full synthetic oil now, was using 5w20 synthetic blend. Would a high volume high pressure Melling oil pump that delivers 30 psig at idle reduce or eliminate the "tick"? Found blogs that state that the stock oil pump does not deliver a good quantity of oil down the overhead cam shafts to the back rockers and lifters. Any help would be appreciated.
Oil shearing in Ford 5.0L engines

"Oil shearing off the journals"? That's an interesting one.
Oil volume is not your problem. If you want to try a heavier grade (such as a Euro 0W-40) that is an easy and inexpensive test.

I cannot tell you if the upgraded pump will make the tick go away.
Can you direct me to the information where Ford claims that ticking is caused by "oil shearing"? Because "shearing" is a term used to describe the change in viscosity of the lube (thinning) relative to specific temp standards of 40C and 100C.
And, once oil eventually oxidizes and the oil goes back up in vis, does Ford consider that anti-shearing? Is that also caused by oil escaping the journals?

The oil's viscosity is very high at cold start, so if the tick is there when cold as well, it seems somewhat unlikely the reason for the tick is low viscosity.
That said, sometimes a person says something because it's easier than trying to provide a thorough, detailed technical answer, and other times a person says something because they didn't quite understand the explanation previously given to them. Your dealer rep may fall into either of these categories (or not).
Yep, when it happens at both temperatures then it's likely something other than the oil.
By "Ford says" that, do you mean the dealer or the factory?
Could a oil that has better polarity/hths be part of the solution? Sound like a job for a boutique oil.
I own a 2024 5.0, and it is a very noisy and less than smooth engine, it has no tick (yet).
From what I read, 'some say' the tick is related to the cam driven high pressure fuel pump on later engines, 'others say' the tick is related to the PCV valve. But it is almost universally accepted to not cause failure. I've heard it in person and it is loud.

My coyote has the tick at 2400 miles. It started after I changed the oil at 1200.
The engine consumed oil with the factory fill at a steady rate. About 3/4 of a quart for the first 1200. Oil consumption stopped with the first change, which was Kirkland 5w-30.
