JA: Many things can cause a car to make those weird sounds. Some simple, some complicated. Fortunately, the mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.

Hello and welcome to JustAnswer!A knock from the engine could be quite a few things. It could be a rod or main bearing issue, piston slap, timing chain noise, or possibly a valvetrain issue. A valvetrain issue would usually cause more of a ticking noise rather than a knock though.Have you determined what area of the engine the noise comes from?How long does it last after startup?
