Knocking sound from my engine

I would drain your oil and strain it with a coffee filter. You will know real quick if you have an issue. Or better yet let the dealer do it.

I'd pull the oil filter, cut it open and check the filter element for metal debris.

Mine makes a horrible knocking or rattle sound when I start my truck very noticeable when I use remote start but I hate taking my truck into the dealer as they don't have anything for me to drive if I drop it iff

That is prob the cam tensioners getting pumped up with oil, nothing to worry about if it goes away after a couple of seconds.

Suggestion: Cell phone camera. Would be interesting to compare ticking to knocking and how long it lasts. I get this on occasion in very cold weather and it only lasts a few seconds. I judge it normal due to weather and that all my GM's and BMW's do/did the same thing. Always sounds like rockers and or valve seats until they get their first healthy drink of synthetic, and always in the heads. If I detected a knock lower in the block, I would suspect something a way bit more evil, like piston slap, wrist pin, rod bearing or main bearing. I seem to recall Ford has a pretty good powertrain warranty. If it's the bottom end of the engine, you'll need to check it out.
