i purchased a dohc zc from HMO a few days ago i got it and i put it in and wired everything..and when i tryed to start it up for the first time...the motor would only turn over 3/4 of one rotation...so i thought it would be a tranny problem because i was using my old 4spd trans ...so i pulled the motor back out and i found out that the trans is fine..the motor still only will turn over 3/4 of one rotation..im thinking that a valve broke and fell on top of the piston and thats whats causing it to do what its doing. what should i do?? i could pull the head and find out for sure if its a broken valve that fell on top of the piston. im not sure what else i could do ...if i wanted a new motor from HMO i would have to pay for shipping to ship it back ..correct? i dont know what to do ..please help

 

Great... sounds like a seized motor. Did you mess with the timing belt or anything like that before you installed the engine? (The trans has nothing to do with this) I would call them up and make them pay for shipping on another motor.

 

I know this sounds stupid, but how's the battery output?

 

the battery output is fine...but that has nothing to do with this..i turned the crank pulley with a long ratchet manually and plus the starter wouldnt even turn it over with the battery on a charger and it will still only turn 3/4 of one rotation..something is definetly binding up..but im still not sure what it is.
any other help would be appreciated

damn this sucks

 

that sucks bro- you're making me worry- i just got my ZC on Wednesday & I haven't touched it yet- it's set to be installed on Sunday- it looks clean- I pray that yours is fine & mine as well

 

Call Steve up and tell him what the deal is. I bought a B16 swap from him, which had very low compression #'s, and he worked with me.
He sent another B16 longblock, and I sent him the original one back to him. Also he paid for everything. The only thing I had to pay was for the extra labor from the shop for dropping the bad engine, and putting up the new one again.

 

yeah i might have to just call him up and see what he can do.
thanks guys...anyone else have anything to say about this?

 

OK..i found out what the problem was...i bent a rod when my dad sprayed ether into the intake while i was trying to starts my car and that is why i can only get 3/4 of one rotation because the rod is hitting the side of the block...now i need to know what kind of internals should i get to fit my dohc zc?
if someone could help me ..with a list of internals or a website i could use on my dohc zc (mainly what rods do i need)that would be cool.
Thanks
