for the past week it has had a bad knock.. mainly at high rev

today driving home it starting stalling a bit then something gave out. There is a bad knock/grind/wind like something is hung up but it runs if i give it a little gas.. but dies when i push the clutch to shift.

did i throw a bearing?

1990 civic hatch
DOHC ZC swap

its not timing. its not alternator. its nothing in the head.

 

I would say yes, but probably not in your engine since your clutch has nothing to do with crank shaft bearings.....
Sounds like a Tranny problem. Maybe your Throw Out Bearing or Input Shaft.
Either way you're pulling the tranny apart

 

It locked up completely when in gear. had to ghetto tow it home.

for ***** and giggles i checked the oil and its very watery.. i hope i didn't crack the block
