360 LA squeel / scraping noise like drive belt on passenger side

15W40, in winter, in Canada, is too thick...... even in summer.
I'm with the guy that mention your oil-gallery plug, BUT
you could have multiple problems, like;
your oil pump relief valve is stuck open, or
the oil-pump drive is in the middle of taking a dump. or
somehow, your 90* filter housing is making trouble.
