Engine knock
Hey guys, been a while since I got on here, V10 is running great. Up til recently its been fine, now it has this tick/knock throughout the power band. It mainly does it under 2500 RPM....I noticed its also starting to burn oil. i burn a quart every 3k miles. I am sure its not leaking. But its going somewhere.
It is driving me nuts cause its top end noise. Is it possible I got a pushrod or something going out, idk how these newer engines work very well. Is this engine a pushrod engine or does it run the rockers on cams?
Any advice would be great.
Specs:
2000 F-250 Triton V10
195,000k miles
4x4
Exhaust manifolds are in great shape.

It's overhead cam, so no pushrods.
If it were me, I'd do a compression check. Burning oil means either ring/piston/cylinder-wall issues, or it's running very rich in one or more cylinders and washing the oil off the cylinder walls - which will eventually cause ring/piston/cylinder-wall issues
If you go this route, as you pull the plugs, number them and keep them so you can tell which ones are rich/lean/cruddy/whatever.

Also, make sure it's not the timing chains...

Thanks, Art.
Not sure about the oil burning, though. Some people here says 1 qt between oil changes is not unusual. I use Mobil synthetic and I usually have to top it off after 3k miles.

I'm running the Castro synthetic blend. I don't think its timing chain because it comes and goes. I also don't think its the spark plugs because it would have tossed it already. This started almost 10k miles ago...... it hasn't harmed the engine's power. I heard somewhere that the rocker arms can start ticking as higher miles mount up. Like I said it comes and goes. I like the comment of the oil consumption. What causes these engines to run rich?? MAF sensor? Does this have a IAC valve? What sensors would cause it to run rich ? Is it possible its injectors?

Exhaust manifolds are perfect, new plugs and coils.
5 OEM COP's, 5 Accel COP's
Tick sounds like one cylinder loudest under 2500rpm, but is also audible above 3500.
Suggested milage for replacement? Just hit 161,000 miles.
Came on suddenly awhile ago.
Thanks,
