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

[Fred]

mine ticks all the time in the colder months in summer it is fine i don't hear it at all. And dealer says nothing wrong with it no codes or lights on the dash. I was like no sh*t no lights but still it shouldn't make that noise i don't think.

Whacked my valve covers with a rubber mallet and it stopped ticking...

did you check your oil level? only on start up?

My injectors tick really bad. Always have.

Not sure about the knock. Check your oil level.

i did check it today before i left work. it was fine a little dirty but fine

The timing chain assembly has a hydraulic tensioner. Effectively, it's vaguely similar to a hydraulic lifter.

Sometime it takes a few seconds to 'pump up' and can cause a 'knocking' like sound.

Injector ticking is a very soft "high" clitter at a rapid pace. Not so much an actual knock.

The tensioner noise most closely resembles upper valvetrain noise or piston slap.

Old/high mileage oil, excessively heavy/thick oil, and/or an older or malfunctioning oil filter that was previously mentioned can all factor in as well.

My Raptor 2012 does the same thing...I will change over to amsoil synthetic and se if that helps...

Mine ticks when cold-stops when warmed up.

I have found that ford and chev engines (big blocks) tick a little when cold when using synthetic oil, but not with real motor oil.

I just let the oil warm, and tick stops-

No it doesnt help...I switched to amsoil 3 months ago.

I'm starting to think that this little tick noise is normal cause mine does it in the morning when it's cold outside I've ran both synthetic and regular oil I've tried a mobile one filter a royal purple filter and a motor craft filter it doesn't help the noise at all. It's not loud at all actually the only time I gear the little ticks are when the hood is up other than that the royal purple high performance full synthetic oil works amazing.
