6.2 intermittent valve train ticking noise at start up ??????????????

[Jake Y.]

i have it too. 10000mi no problems so i'm just doing long tubes so i cant hear it.

I have a friend who has his raptor down for 30 days while ford replaces the heads due to a bad tick once warm. Apparently the parts come from Roush, I still would be crazy if mine was down that long for even a full engine replacement.

Anyone else with this issue? I have the noise but feel it is normal, but this bothers me!

Hell yea it bothers me too ! Internal engine noises of any kind big or small should not be "ignored". And its definately a lifter,which quiets down once oil gets to it.

The Ford 6.2L engine is an OHC design.

Does it even have lifters?

Mine does the same thing, it's kinda got a slight miss about it as well but smooths out once it's warmed up. I just figure it's normal warm up although it's still a little nerve racking. Anyhow, I suggest letting it warm up a couple of minutes before taking off in the morning...more so if it's a real cold day/night.

The 6.2L engine has a rocker shaft that rocker arms mount on. One end of the rocker arm has a lash adjuster and the other end of the rocker arm has a roller bearing that contacts the camshaft lobe.

The idle quality of the 6.2L engine in the Raptor is "rougher" than the 6.2L in the Super Duty because the camshafts have more overlap, giving the Raptor engine higher horsepower than the SD. This idle is normal for the Raptor as the engine has been specifically tuned and designed for higher performance, over idle stability.

The engine is not misfiring.

Great info, thanks!

I understand but is it supposed to jerk or shake the truck around every time it does it? The last time I had a truck running like this the MAF was out of tune or calibration. I'm going to have them check it out the next time I get some free time.

Do you have a "soft" code stored? Meaning the ECM stores the fault, but does not illuminate the MIL (malfunction indicator lamp) because it hasn't reached a threshold for warning.

Maybe hook up a code scanner and see if something is there.
