@Meir,
Thanks for confirming. I think my brain is losing its logical troubleshooting capability.


@Eric,
I read a few posts that pointed to PS and spark plug. I topped off the PS fluid and it took very little. So, maybe the PS pump (?) is target? I did have to tighten the plug for cyl 5 some time ago. So, going to recheck that as well. But, the noise is coming from just about where the crank pulley (the one we use to put TDC) and I'm not able to nail it down. I shall make a video/audio and post. Maybe that'll shed more light on this.
