i was driving my 90si with a sohc vtec d16z6 and all of a sudden the timing belt snapped...i had a feeling the a pistion hit a valve which it did... we put a new timing belt on and set the timing it started up but was missing bad...thats when we found out it was missing but anyway we heard alittle knock too...could it been possible to have threw a rod or done any piston damage ..any help would be good ....thanks

 

Probably just the bent valve tapping in its seat. And your rods/crank are fine, even if you dropped a valve they should be ok. Your pistons "may" have a knick or 2 in them from the valves, sometimes you get lucky and theres no damage, sometimes you arent lucky.

 

if u threw i rod i dnt think it would turn over and start. mine didnt when i did that. ya if u want to be safe just check the combustion chambers and pistons. good luck

my timing belt snaped a couple of months ago while it was running. i put a new timing belt on and i thought a had bent a valve cause it was miss firing and puttering alot. i thought i had the timing on right cause i used all the timing marks to do the timing but it turns out i was off. one of my mechanic buddys fixed the timing now it runs like a champ. now if only i could get to pass emissions.

 

im also kinda lookin for the d16z6 head...for kinda cheap i think it would just be easier to find a new head kinda low on money too and i really dont wanna get rid of it..the motor was one of those abnormally strong ones. i kept up easily with dohc and my motor was completely stock. if ya know where to get one cheap- i looked on ebay they were around 100 to 150 ill pay around 100 with shipping or can talk about it
i wanna atleast get the car running again thanks for some of the help
