LT1 ticking under load

georgez32 · 08-18-2018, 08:37 PM

So I started to notice a very slight ticking noise coming from the engine bay and it seems to be load based rather than RPM base. Basically anything over 50% throttle in any gear I can hear a very faint ticking noise that is independent of the exhaust rattle from the back NPP. Also, the noise is only audible when windows are closed, with the windows down, that ticking wont be loud enough to be audible

I'm wondering if this noise is the DI system or could it be a exhaust leak? Exhaust system is stock so I'm not sure if that could be the reason.

Any input would be awesome
