Hose from top of engine to intake

What is the hose that runs from the upper part of the intake hose to the rear passenger side of the block. This is on a 93 GS w/ 1.8L. Need to replace it cuz the one on there is some bootleg shit the guy i bought it from put in.

Thanks.

pcv hose dont stress out about it.

the pcv and hose are on the the intake manifold.

the hose that goes from the intake tube to the valve cover jus transfers heat, either get the oem one, which is about the ugliest pos. or jus use any piece of tubing to connect the two. jus dont be gay and put a breather filter there :bored:

it relieves crankcase pressures chief.

:up:

Yeah, any hosing will do. Not a prob. Won’t kill your engine to go a day or two without it either if you have to.
