Help! Wiped cam lobes? - Video inside

Hey so pretty much done here I think. I've got it mostly timed I think. The oil light flickers on and off though, and sometimes its just on. Also sometimes its just off. It didn't do this before...

Is this a sign that there's an oil pressure problem? Or could it just be a crappy old sensor?

Don't take a chance. Install a mechanical oil gauge and see what you have!
