So I had a lifter go bad... what else should I check ?

[resq302]

Ok, this luckily isn't my charger but it is my daily driver.  My 07 F150 4x4 started making a tapping / knocking noise similar to someone putting a playing card in a bicycle spoke when the wheel was spinning.  I brought it to the dealer who checked into the noise and found that it was a bad lifter.  Is there anything else that could have gotten damaged from a lifter colapsing and going bad?

If it just collapsed and wouldnt hold pressure, assuming that there was nothing wrong externally with it (wearing on the face/cam lobe) it wouldnt cause any damage, it some cases it could cause a pushrod to come out, and worst case if it falls apart physically it can sure damage things. But if it was just as simple as it went bad, you oughtta be fine.

Funny thing is that at idle, it did not make any noise.  Its when it was under a load is when it would start making the noise or if it sat over night and fired up first thing in the morning it would knock like a diesel truck (I wish they made a diesel in a F150).  I kinda have to think that they are roller lifters in cars and trucks now for mileage and less wear.  If luck has it, I will be picking up the truck tomorrow.  They have had it since Mon morning.

The lifter probably just collapsed , bent pushrod would be the other thing to look at , if the face of the lifter failed there could ba a lot of damage , being an 07 it would have roller lifters though so if the roller is still in the lifter you are ok

umm, just happened to me at the begining of the car season here...

I ended up having to replace the cam... if the bottom of the lifter is dug in.... replace it all. Don't risk it.

and I got a much better and bigger cam out of it heheh

That TSB is for the cam phaser for the variable cam timing.   According to the service manager, that is not the noise that they experienced, but more of a bad lifter(s).    I guess when they call back, I will ask them what the condition of the cam, push rods, and everything else were and if any of that stuff was replaced.  If problems down the road should arise, I wonder if they will fix it if it is related to the lifter going bad?
