There are a number of wise people on this site that think replacing the HB should be on the PM or Refresh list. Clearly it can do a fair bit of damage if it separates fully, but perhaps the belt tension reduces the risk of that outcome somewhat. I decided to go with one from the dealer and it was not cheap. RockAuto now has a few at different price points, I have no clue as to the quality but I also find it hard to believe there is enough demand for this thing to have several manufacturers tool up production.

Yeah copy that. I have one ordered with a new bolt from PartSouq. When I had it off I noticed separation starting on the back rubber.

An update after more replacing parts and troubleshooting. The new HB didn’t resolve the noise. I have taken it to a few experienced techs in my area with their guidance I popped the lower oil pan off to see if there was any loose hardware sitting in the bottom of the upper pan, didn’t find anything with my bore scope or magnet. But I did find loose FIPG and fine metal like sand. I made sure to check the baffle and oil pickup tube to make sure they were tight and there was not movement in either. I took the valve cover off and measured my valve clearances and one exhaust valve on cylinder #4 was one thou off on the high end of spec. Looked in all my cylinders with the bore scope all but #4 piston head looked normal. Also looked in the timing chain cover and found a crack in the housing. I’m at a loss and will be brining it back to the mechanic that did the head job.

Are you sure that is a crack? looks like FIPG strings to me.

It was not. I’m unfamiliar with the bushing. Where exactly is it?

thanks to @rmgarage for the thread & pics
I'm rebuilding my 1FZ-FE and I just got the block back from the machine shop. I specifically asked them to not clean the block with a caustic mix as to not damage the oil pump bushing, and they told me they used detergent. After picking up the block, I noticed the bushing is a little discolored but doesn't seem to be corroded, damaged, or weakened in any way. The bushing is smooth, there is no scratching/pitting/etc, and looks good. What are your opinions? I thought this was a brass bushing...it seems to be aluminum or steel?

Oil Pump Bushing
The oil pump bushing is not available through Toyota and is often needed for a proper engine rebuild. This is a machined bushing that matches the original in design, however is made out of navel brass which is more durable. In addition there is an install tool available to aid with installing...

Gotcha. I would need the timing cover off if I wanted to replace that right?
I wonder if you could pull it out with this kit..

I use this for pulling bearings where you can't push from the other side.
thanks for the link - cool tool
