Is this engine noisy or am I just expecting too much?

[TORQUERULES]

I'm new to the EcoBoost line of engines and honestly I'm not sure what to expect my truck has almost 13,000 miles on it now and I haven't really paid any attention to noises or anything like that and recently I've just been running with the AC on and the windows up and just not even listening to the radio. I've noticed that sometimes under light acceleration I'll hear what basically just sounds like valve train noise mostly coming from the driver side of the engine and when I roll the windows down I can't even really hear it outside. The only time I've actually been able to is right beside a building. I'm not sure if this is normal, if it's the direct injectors, the hpfp, or maybe even a slight exhaust leak because I have the mbrp exhaust which doesn't have a flex coupler and I haven't tightened it up in a few months. Am I going crazy, or is this just something that's intrinsic to this line of engines? It's not very loud, it's faint and like I said it just sounds like a sewing machine kind of valve train noise like you would have with a set of mechanical lifters or something like that and it only happens under light acceleration and light load. Most of the time you can't hear anything at all other than the engine and if you get on the gas a little bit and it stops. My previous DI engines have all been Mazdas and they really have a lot of sound dampening under the hood.

That's what I am thinking.

Pretty normal noises, between all the cool technology up there. sounds worst for me though my hearing aids amplify all that noise so it sounds like a box of rocks to me. ?. I sprung for the engine cover helps a little.

It has surprised me. I guess Ford didn't really worry about NVH with this truck.

MUCH louder than the DISI turbo in the Mazdas. That incessant clicking noise is the injectors. The HPFP is pretty dang loud too. Louder than my mazda with the autotechs. I'm getting used to it knowing that its just normal operation noise. As long as it keeps making those noises, I'm content lol.

It's a 4 cylinder compact truck, not a luxury F150. Based off my experiences, all of the compact trucks have a little noisier engine (regardless of the engine). And you are not going to have all the sound dampening materials a full size would.

Just drive it and stop worrying.

This is the first compact truck I’ve owned, and by far the smallest engine I’ve ever owned (prior vehicles 5.0, 4.6, 3.8, 3.5) but this truck is a little beast! I’m still adjusting to the odd clicks, the almost electronic buzz at low rpms, etc. but if that’s all we have to deal with to have this much power and fun out of that little engine, I’ll take it!

If it had the "mat" that most DI equipped cars from Europe it would probably reduce the noise alot.

My wife's DI Honda has some cool whistles and such too lol

I found that the engine cover significantly reduced the engine noise.

I think the cab just allows a lot of noise. I can hear people talking in the drive thru line like they're next to me even with the window up

Yes.

Lol you shoud hear old Nissan Fuel injected engines!! You thought the EcoBoost was noisy? 1980's nissan fuel injectors are louder than a Deisel!!!

I kind of dig the noisy fan at startup. I'm glad it doesn't last too long though.

While the engine can be somewhat noisy, I find the cab while driving to be very quiet - probably the quietest vehicle I've owned. Maybe part of it is the ANC, maybe part of it is insulation - I'm not sure, but I'm very happy with the cabin noise level.

No, its a bit noisy. Not quite to the level of my '96 Cherokee Spt with a cast iron straight 6cyl 4.0L. Had to run straight sae 30 in that one..

The fan noise was the first thing my wife ask about when we took a test drive. Thankfully because of this forum I was able to tell her it's all good. And yes, mine sounds like a sewing machine at idle but, I'm used to it now. Just the nature of the beast.
