How hard should a rebuilt motor be to turn?

I have used the factory flywheel bolts. The strange thing is, I can't replicate the problem anymore. I have installed the transmission, and drove the car for a short bit. I had an oil leak coming from the oil pump pressure relief bolt. Which lead me to this thread: https://www.miataturbo.net/engine-pe...ht-pics-58278/

I took it out and used a thread sealant and put it back on. Now I have a small leak from the front of the oil pan. I suspect the front main seal. But I am also now throwing a CEL, the car is idling a little rough and it randomly struggles to start. I suspect I'm off by a tooth on my timing belt. I will double check both next weekend. Does this look like it is properly lined up?

Hm, it should be TDC, but I'll double check it tonight. I think I may off on my timing belt based on this thread: http://forum.miata.net/vb/showthread.php?t=227838

I know its hard to see, but this is the current position of the timing sprocket. I haven't had time to remove the accessory belts and timing belt cover. I'm temporarily working two jobs.

I found this thread when I was looking up CEL codes:

This is why I suspected the timing belt being off. I will double check the CEL code as soon as I get a chance.

So have confirmed my oil leak is coming from my front crank seal. I used a flyin miata front crank seal install tool and it pressed the crank seal further in by about 5mm. My question is, should I replace it or try using it again? The front seal is few months old and has about 15 miles of use. I also plan on using the cam seal installing tool to double check the cam seals.

I also had a chicken that would not leave my garage, no idea why.

If you happened to score the crank when removing the old gasket, you won't get a decent seal with anything. As a habit, I only use OEM seals, but it seems most people who've had leaks found it was caused by either a nick on the seal surface (crank) or an over/under depth placement of the seal.
