ok for some reason my car (95 hatch ls swap) didnt come with an oil breather. We put in a new block but don't have an oil breather. Is it okay to cap the hole on the block for it off and bypass it, or is there some vital return it supplies. I have an acura service manual for it, but can't really make heads or tails on whether this would be ok to do. Also if someone has done this what did you use for your cap on the block, a freeze plug? What size and where did you get it? Thanks

what model ls do you have in the car...94 and 95 ls came with the oil breather but the 96-up did not...

He's right. I would add the breather and route the pvc to the intake manifold.

yeh those breather helps the engine alot. their good to have around.

alright thanks guys. To answer your q, its out of a 94.
