I can't find a cause Dragsix. When I started chasing this noise, I replaced the alternator, water pump and belt. Still squeeled. Then I ran it with the belt removed so nothing up front was moving. Still squeeled. Didn't seem to squeel when I ran it with the balancer removed. I have not put it back together yet.
I would like to do the timing cover bolt mod. Wondering if you guys think that is a bad idea? In looking at this, the existing holes in the bearing cap are about 11/32 (.344 ish). This is about 1/32 (.031 ish) over the tap drill size for 3/8-16. So I'm not going to have anywhere near the full thread depth for a 3/8" fastener. Going bigger than that could create clearance issues, not sure. So I'm wondering what experience others have had?
Thanks
Dave
