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

[NickPic83]

Figured it was normal as well.

Its normal, scares me all the time too... Not the most reassuring start-up...

Both of my Raptors do this.. More pronounced in the 2012, than 2011.. Might be the ABS plastic valve covers on the 2012's....

Can any of you guys pinpoint where the ticking is coming from on the engine?
It could be a solenoid in the emissions system that you are hearing as it is cycling. On my soon to be former vehicle, there is a solenoid right by the power brake booster that makes a very audible ticking noise. It sounds exactly like a lifter click. I went around the engine compartment with a long handled screwdriver, and used it as a stethoscope to locate the source of the ticking. When I put the screwdriver on the mentioned solenoid, you could feel the ticking as well as clearly hear it.

Just a thought.

As long as your not in Iraq or Afghanistan I think you'll be fine.

Yeah I had taken my raptor back to ford asking the same thing. I was told its just the injectors are just noisy . And that its just not the raptor , its some different models as well

You can hear it in a lot of exhaust videos on youtube.

Here is a link to a Big J TSB post from last year. I have this audible click occasionally on my 2010 6.2

My 2011 does it also, main thing is it goes away in a few seconds. There is a strange ping to the exhaust underneath somewhere near the header junction I hear when I start also but that is only for about a second also.
