i have a 2004 Ford F150 and i hear a ticking noise underneath the hood. i have had the oil checked and changed and its ok

Is it a mechanical noise like a lifter that has too much clearance or is it an electrical sound like a spark plug wire arcing?

It's more like a lifter

it could be a timing chain hitting the front cover

My nephew had a F250. He told me "clicking" caused by exhaust manifold, expensive to fix $2000?

fuel injectors
