Need Help

Hey guys, My 89 f150 302 has a knock and it sounds like it's from the oil pan. But I don't now what i'm looking for. I had to changed the oil pan gasket anyways, so I took the oil pan off. The knock is mostly heard when you let off the gas and it's going down to idle, Knock,Knock,knock. There is no Dents or scraps in side the oil pan. I was told to see if anything was loose or scraped up. But nothing is. could anyone help me Thanks.

Bad rod and/or main bearings is the likely cause.

Pull a rod cap to see how bad the bearings are. If you have brass instead of babbit material, pull the motor and go through it.

I prolly should add that one rod might be a little looser on the journal than the others, pull that one for sure.
