Hey guys, new here. Got a 2008 Expedition that I think may be due for some major work. Last week, wife was taking it through a drive thru, got some horrible noise and some codes. P0345, P0340, and P0316. I replaced the cam position sensors per the codes. Yesterday, same noise happened for her again, no codes this time. Also, this weekend, noticed a slight misfire on acceleration to highway speeds, but once again no codes. Thinking ata minimum our timing chain and guides might be shot, but also the VCT solenoids? Time to do it all?


Edit. I should mention I don't have any rattle on startup, or noises I can tell beyond injector clicks. I've yet to experience this issue, as it has only happened for her, and only after she's been driving a while and it's warmed up.

here's a TSB for that. you could try just replacing these parts and go from there

With the amount of miles we have, do you think it would be worth doing chains and guides, as well as phaders, at the same time?

its your call, how long have you had the vehicle?

​​​​​​About 2 months, but we would like to get 5 years out of it.

If it was me, before i go ripping the whole motor apart, especially because you have no start up rattle. I would replace the solenoids and go from there

Just an update on this, we ended up having everything done. Went with the cloyes timing kit, melling oil pump, Ford phasers and VCT solenoids. Only done about 2k miles since then, but so far so good.
