Checking out the aftermath

[want_a_gsx]

Long story short, after blowing the headgasket on the newly rebuilt motor, I drove the car home. Afterwards, the motor would only turn about 90* so figured it was a bent rod, caused by the attempt to compress coolant in the cylinder. After dropping the oil pan, I decide to turn the motor and it turns fine. Haven't removed the crank yet, but all rods seem to be in great condition.

Removed 2 of the 3 crank bearing caps and these are what the bearings look like. If anyone has any input as to the condition of any of these parts, or why the crank is finally turning, feel free to share.

I believe that the higher compression, with overly advanced timing, and extremely loose head studs contributed to the destruction...

**Note: the crank was not being stopped by any valves because it didn't turn, even after the head was removed.**

Here are some of the bearings...

wow dude , that sucks big time... did you ever retorque the head?? i had to retorque mine about 4 times untill all studs were firm at 80lbs

... the head seems alright but 2 of your bearings look like they got a deep mark on them, or is that the oil?

Ouch! #3 is done! Is that grooved crank bearing also #3?

Honestly, that's where I completely messed up. About four studs were a bit too loose when I started to remove the head...

Those are definitely deep marks on bearings 3 and four.
