should there be a crank case breather box on a b18b....there was one on my b16 but not on this one and i went lsvtec do i need that box..or no...or what should i do?

 

i dont think so

 

Are you talking about the box on the back for the PCV? I would think the B18 should have one. What happened to yours? Just a new motor?

 

i had a b16 and i want to go lsvtec and i went to put the box where the pvc go back on to the ls and it had a block in it....but i have a b18a1 that has the hole for it???....could they be different being one is obd0 and the other is obd2??i just wana kno if it will hurt it not having that on there...and im very greatfull for everyones help

 

Hmm, that's odd. Where did you get the LS motor from? My D15 is an OBD0 motor and it has the PCV breather. It just might be how they did those LS's back then, I honestly haven't seen one, well the back of one anyway.
I highly doubt that it'll hurt anything if it came that way from the factory. Or is the block something someone did to it before you had it?

 

it looks and feels like sumthin put in from the factory

 

Well then if Honda stuck it in there, then I'm sure it's fine. I don't think you'll hurt anything. Just roll with it man.

 

i was just maken sure....thanks

 

No problem. Later man.
