Engine noise

[Froggy372]

I have a 2007 Ford Edge SEL AWD 3.5 2 weeks ago it stalled while I was driving down the road I got it home I did some research I replaced the throttle body the car ran great after that this past Monday it was being driven by my son he called me said the car stalled and when he restarted it it was making a funny knocking noise I got it home again did some more Diagnostics it gave me soft codes p0012 and p0022 both are camshaft position sensor codes so I purchased two new camshaft position sensors install them last night and I'm still getting a knock. I'm wondering if this point if the knocked is linked to connecting rod bearings. Any input would be greatly appreciated at this point

These codes could be due to:

cam position sensors

vct solenoids

cam phasers

timing chain

etc

 

I suspect you need to open up the front/timing cover and do a complete timing set/water pump job.  Might also want to look at used replacement engines instead over at car-part.com, LKQ, etc.
