Dry start issue

[SnowDrifter]

Get a nasty noise on startup if the vehicle has been sitting for a few days. Thought the adbv on my oil filter was shot so I did an oil change. Still there.

It happens so berifly its difficult to tell if it's coming from the engine or transmission side of things.

Oil pressure while running is normal. No odd noises or other concerns. It's just this damn clatter on startup..

Haz anyone experienced something like this? Any idea what it could be or point me in the direction of some sort of remedy?

Can’t really hear anything in the video but my 04 5.3 started a little piston slap around the same mileage. Really nothing that can be done about it.

I bought a brand new 03 Ford 5.4 that sounded waaay worse that that at 12k miles. Needless to say I got rid of that truck real quick.

That clatter clatter just after the starter. If I start it up before it sits for a few days, it's dead silent

Here's normal startup if it's been sitting for a day or 2

My thoughts are that your starter is on its way out, im not a mechanic but im thinking on cold starts, the starter is cold and the spring is not retracting fast enough and getting caught on flywheel, when hot starts it can retract normally... maybe, maybe not.. something like this... my 2 cts... maybe some pbblaster or something will help..

Possibly. I know it's a bit tough to tell on video but it sounded a lot "deeper" than would be a starter


Wonder if pulling the injector fuse and cranking it for a few seconds then popping it back in would give anything diagnostically relevant

Piston slap and lifter tap lasts a lot longer then that on cold start...slap and tap is normal the older ls’s so i guess you gotta get under the hood bud

I can't tell anything from the vid. It's like your mic was focused on the sound of the key being turned and muffled everything else.

Mine has a lifter tap for 2-3 seconds after it sits all week. I'm sure it's an AFM lifter bleeding down.

Will get a video from under the hood soon. I more or less know what I'm listening for in the video so it's pretty easy for me to tell. Guess it's not that apparent lol

Even on your normal start vid you can hear a little catch at the end of the starter cycling. Very slight, but noticeable. The starter may be hanging up like previously mentioned.
