Ok so i tightened the crank bolt - i did put the smallest possible drop loctite blue that i could squeeze out, at 3/4 of the length of the bolt and smeared it all around a couple of threads.
I then tightened to 40Nm, which felt surprisingly easy - i hope my torque wrench is accurate enough.

But when doing the 90° turn, i have this bad feeling i might have overtorqued it.
it manage to get it to like 89° in 3 turns (last one with foot on breaker bar - 60cm ~23", 1/2"), and my both hands pulling on the crankshaft sprocket holding tool. Then i went one more time (i had to use my foot again), because i wanted that ˛$%&/%& 1° degree (ok, maybe 2-3°, but not more)- force was building up, but when it moved, i THINK i felt it being a bit easier than the last push...
...mind i did it with my foot, so not exactly sure, maybe muscles tricked me.
I stopped immediately after "feeling" it, i checked the markings on the bolt&pulley, and it moved 1mm, like 2-3°max.

Could have i overtorqued the bolts beyond its limit with this small movement? It's a Ford OEM bolt, a mechanic told me that aftermarket one can tear even BEFORE reaching the specs, he's had cases like that.

Static friction is bigger than kinetic friction...so to overcome the force needed for that last degrees, was bigger than when doing in a contionus move...

I stupidly went to reassemble everything, thinking lala, it's fine, but that feeling has creeped behind me and i'm not sure wether to put the starter in and risk ruining the engine,
or try to get the bolt out and risk snapping it...

How close is the manufacturers torque/angle spec to the definite "dead" limit of the bolt? like.. 100% or does it have any tolerance for overtorquing situation (t-wrench tolerances, angle gauge tolerances, etc)...

Help appreciated more than ever.
