Hello and welcome to JustAnswer!

There are quite a few things that can cause a noise in the engine, especially depending on what you're actually hearing. It could be a valvetrain issue, a piston/wristpin/bearing issue, it could be an engine driven accessory. Some disassembly might be necessary to determine the cause of the noise.

Can you describe the noise in detail?
