I made a tool to get that crank pulley held. It is amazing: search on how to hold the crank pulley and all you really get are tons of pages and videos on how to remove the pulley. Virtually nothing on how to install one, other than someone saying "install it" or saying something about using the OEM tool. No one rents anything that will work, and when I searched to buy a tool many I saw did not look like they would fit this pulley design. I don't believe I got to the torque spec, as my torque wrench never clicked, but I did tighten it. I may ask a shop to tighten it to spec.
That's a 1 1/4 floor flange (anything smaller would not work) and a 1/2" x 24" black pipe. I got some M8-1.25 x 45mm bolts and nuts, and widened the holes in the flange with my drill to fit the bolts. Then drilled a hole through the pipe to bolt to the flange. It lined up fine when I put one hole in the pipe and secured it, then placed the tool onto the pulley to make sure I could line things up. Used the next hole in the flange to set the pipe. Oriented it so the lip went into the pulley. The other holes matched up with the bottom two slots in the pulley, which looks like this:
It all fit really interesting - I fit the tool behind the knuckle, and the bottom rested inside the wheel well, pressed up against the top of the well. The lower bolts caught the leading edges of the bottom pulley slots, and I could torque the pulley crank bolt. The thing would slip when putting a large amount of torque on it, but it did turn the bolt more. Anyway, seems OK for now.
Ran the car around the block a few times. VERY quiet engine now. I had both front windows down, and it was almost silent in idle. Idles around 600-700 rpm, no shudder. LOADS of pick up and go. Feels like when it was brand new (which in a sense it is). I didn't time 0-60 (will do so sometime this week) but man it got there quick. Nothing to cause an alarm - smooth, full, power. No shuddering at idle even after running hard.
I did almost freak out at the gas station. Since it was almost empty I wanted the first gas to be Chevron. When filling up thought I would check the oil, since I had not looked at the dipstick since putting the oil in (Mobile 1 5-20 synthetic). I thought it has circulated a bit, so now is a good time to read it. Could see nothing on the dipstick. I touched it and my finger came away with a sheen of oil. Wiped the stick, put it back in and out, could see nothing on the dipstick. Again a sheen of oil when I touched it. I figured the engine is so clean, the oil so new, you can't see it on the stick. Started the car and the check engine light and oil pressure light came on. Crapola. Shut it off, ran inside and grabbed a shitty 5-30 oil the gas station had and put the quart in. Still cannot see anything on the stick, still get some oil on my finger tip, lights went off. When I did the oil I put in whatever the manual stated for the new filter (can't recall off hand amongst all these cars). So I am thinking since the engine is new it needed more than the norm. Maybe. Have not had any lights come on except that one moment. Will keep my eye on it.
And there is absolutely no leak - not on the ground, not under the car, not in the engine bay. So I know no oil found its way outside the engine!
When the stick is wiped no oil gets on my finger tip. I can feel oil up above the fill line, where it would be with an extra quart in it (when it was using oil, I would often put in an extra quart to keep it going longer). So, it is just super clean. Wow.
