Here's one for the techies

[ORRadtech]

Thanks for your collective input folks. I've been advised that they want to run some more checks but have confirmed the 'noise' is from the off-side cylinder head area (that's drivers side down here). If it's internal they will just put in a new engine as they don't strip down and repair things these days (so I'm told). I'm staggered; in my day we repaired stuff, we didn't just replace whole engines without a closer look. How the world has changed eh!

Another thought on whole engine replacement is that they return the engine to the factory to be examined to discover the issue. I know Harley Davidson often returns replaced motors for that specific purpose.

Pity the bookies and lawyers won't let Ford sell "returned crate engines" by the pallet to the public, no warranty, as-is, where-is...

My GT has had what I can best describe as a belt 'whistle' on cold start, be it water pump, alternator or whatever. There's more than one. As it warms up, the 'whistle' goes away.

Crazy, my 19 PP2 does the same thing. 600 miles on the odometer, days here have been in the 40s. Subbing as I want to see if this is worth taking to service.

I hear a chirp that sounds like a pulley on startup which I suspect is what the TSB is referring to. I haven't had it looked at yet either.

Below is a Google Photos link I made with a clip of the sound.

in your day we sent a decent cross section of the male population to tech school where students got to rip apart and reassemble engines. You can't even find a basic welding class anymore. The technicians these days probably have no idea how to build an engine (or they did it once in school) and therefore the manufacturers are more interested in a "controlled item" aka fresh factory engine being installed (the lack of QC notwithstanding) for the purposes of repair resolution than some unknown possible numbskull taking a swipe at the power unit.

Yes, I think you're right. I wonder what they teach apprentices these days. It seems any fault under warranty is dealt with by fitting new parts, even a whole engine for a slight noise on cold start.

They did mention that the original would probably go back to Ford for inspection. They also said it was quicker and cheaper to replace it than strip it down and hope to trace the source of the noise.

Mine did it from day 1 with a handful of kms on it. I thought it was a belt but they said the belts and tensions were fine, although they couldn't hear anything because it was warmed up. They told me to put some more mileage on it and it might settle down, but it hasn't.

If my sound is related to the TSB being discussed (i.e., the primary timing chain tensioner oil pressure relief valve), then is this just a noise, or is this is an issue that will result in some kind of engine issue(s)?

Good question, but who knows. I'm not convinced an oil pressure relief valve issue could sound like this...

This is what mine sounds like.

 

[Snakes&horses]

Thanks! Do you have that TSB number by chance? My engine is not currently doing this (2019 w/8800 miles, built pre the TSB date) but if it starts I will refer to this TSB if it starts and I take in.

Issue: Some 2018-2019 F-150 and Mustang vehicles equipped with a 5.0L engine built on or before 30-Apr- 2019 may exhibit a chirping type noise from the upper engine front cover area at warm or hot idle. This noise may sound similar to a front engine accessory drive (FEAD) chirp noise. This may be due to the primary timing chain tensioner oil pressure relief valve. To correct the condition, follow the Service Procedure steps to replace the primary timing chain tensioners.
Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following conditions:
• 2018-2019 F-150/Mustang
• 5.0L Engine

[Blue Moon]

I get a little squeal like that in my EB when I start it and back out of the garage. It seems to go away by the time I'm on the road, or maybe it just gets drowned out by engine noise. :shrug:

It's interesting that you have heard it on the four cylinder. There must be some common componentry somewhere

 

[Dfeeds]

I have the same squeal from the thread you linked but only when cold and it goes away when the car is warmed up. I haven't taken it in because of that (TSB specifically mentions hot or warm). I guess maybe warm? I don't know, but I already had the engine replaced and don't want to deal with that again... FWIW, another member had the same squeal and also replaced the tensioners. They claimed it solved the sound but upon inspection there was no weight difference (implying the tensioner is being shreded) or noticeable damage, but they also only had it when cold. I'm gonna stick around, though, and see what the outcome is.

in your day we sent a decent cross section of the male population to tech school where students got to rip apart and reassemble engines. You can't even find a basic welding class anymore.

That reminds me of when I first started getting into cars. My buddy paid for classes while I just started hacking at things and using the internet. Several years later I offered to help him rebuild his dad's Javelin and the fool knew fuck all. It actually amazed me how useless he was if he couldn't find an answer in a shop manual. One can use this as an example to say there's no substitute for experience, but I'd think a two years of college would provide some sort of problem solving. Then again, it was community college...
