ok i have seemed to to of lost my crank shaft bolt well working on the motor i tried one from a dx civic and its to small does anyone know what will fit i dont remember if it's 17 or 18 mm anyone know what other motor has the same bolt size and thread any help i would really apperciate it thanks everyone

 

I wouldnt use just any old bolt for the crank pulley, go to your local dealer and pick one up for a 88-91 crx si. d16a6 uses the same crank pulley bolt, they are pretty cheap too, like 5-6 bucks if I remember correctly.

accually they are 7bucks last time i 'checked'

 

Well if people dont missplace them, or dont tighten their crankshaft bolts, you wouldnt have to ever buy them, now would you? guess, you know all about that, LOL
