Scotty, I have a 1991 f150 4wd manual transmission. When accelerating I hear a clack or tick noise. I assume it’s the exhaust system but also read it could be the secondary air intake. Thoughts?
The engine is the 4.9L inline 6

Waffle to make the noise while you're just rubbing it up in the driveway then it's easy just have somebody rub it up and you crawl around to see where the gas is escaping and the noise is coming from
