Why does my gas truck sound like a diesel
I am a female and I need to know if these guys are trying to take me for a ride because of it. I have an 08 F150 5.4. Earlier this year I had a knock. The death tick. Got the new cam phaser kit and timing chain done, ran great. Couple months later start hearing a rattle, literally like a rattlesnake, for 2 seconds max after starting. Drove like that for a couple months, didn’t care too much. Till I go to start it a couple weeks back and the whole thing is shaking uncontrollably. I had moved cities at this point, so Tow it to a different shop, get all spark plugs replaced plus both VCTs (which should have been done at the same time as the other timing I know) drive it out of the lot and this thing has the same (or so I think) knock as it had before I got the phasers! Sounds very similar to a diesel, also kind of sounds like an engine that’s been ran out of oil. Which it hasn’t. So take it straight back to that shop, and they tell me sounds like a bearing. Excuse me?? The odds of it being unrelated to what they just did are astronomical, let alone it being something so severe as a bearing and needing an engine swap. What do you think, is it possible for them to have destroyed the new phasers by not putting the VCTs in properly? Or what the hell. I’m just having a really hard time believing I’ve all of a sudden got a bearing gone after two different guys did timing related work.

What all did they do with the phaser and timing chain? The entire timing job requires a lot of different parts and a new, high volume, oil pump. Is there any way you could list all they are claiming to have replaced?
knowing the history of these engines...if they didn't use ford parts(with the exception of the oil pump) you did the engine no favors
sounds like the chain guides are worn and the tensioners are shot too.

Yeah, they likely used cheap parts and didn't execute the job in its entirety. You need phasers, chain guides, tensioners, HV oil pump, VCT solenoids, clean oil pick-up screen. It's also a good idea to do lifters/rollers. All parts need to be Ford (the oil pump is the exception here, most use melling), gaskets, etc.

So it shouldn’t be the bearing like this one guy is saying? If it’s all timing still I will just get a ford dealer to do it, but is it worth it? That’s another 5 grand for a truck that’s only worth 11

and if the top end was starved of oil for long enough the cams will eat into the heads and then you need new heads...that's why here 90% of the time if we get a 5.4 Powerstroke we price a whole engine. better warranty and its usually more cost effective for the customer in the long run

I'd venture to say no, it's a not a main bearing of any sort. Your noises and shaking are indicative of the timing system being in shambles. Like Dj said, if it's went on too long there's a good chance one or both f your heads are shot. I believe it's the passenger side which usually goes first.

it COULD be...its hard to play internet diag. At this point I would either get rid of the truck or put a motor in it
