I have a 2005 f150 5.4 v8
Seller told me it was a v6 and didn’t run very often. I bought it like 5 months ago and it hasn’t had any problems yet. I went through everything today and found all these things that look like problems. Can anyone tell me how important these things are and if it’s normal wear and tear at this point? I’m fairly handy but would rather pay someone to do it right if it’s important.

I’m most concerned with the age of it, is there anything specific I should look for that usually fails?
Thanks in advance for the help :)
