Hey guys, this is my first post. I just purchased my first Honda, it is a 1988 CRX Si, D161A6 Motor. On the bottom of the intake manifold there is a breather hose for what I believe is a PCV valve, the valve has a blue tip. That hose is broken, and if I am correct it throws out a lot of steam when the car is running. I drove it up my road and the steam out of it got so hot that it cracked my headlight cover. Is the steam actually coming out of that broken hose? When I say broken, I mean completely in half. Any help is appreciated, thanks.

 

no steam at all should be coming out of the pvc.

if you have steam coming out somewhere close enough to crack a headlight you have some sort of coolant leak around the radiator.

 

Is there a different hose behind the manifold? Because I watch it pour out from there. Nothing at all is coming up from the front, just straight pouring right near that hose.

 

I also just remembered that the coolant drain bolt on the block got rounded off before I could remove it, so it is about 1/4 loose. Could that be the issue with the cracked light? There is still a lot of smoke/steam coming from below the intake manifold also.

 

Please guys, I really have no clue what to do. If the steam issue is just the loose coolant drain plug, then I can fix that. But would smoke or anything be coming out of the broken breather hose below the intake manifold?

 

tighten that bolt and check all hoses that coolant runs in are good

 

probably a coolant hose on the back of the block

 

I replaced 2 coolant hoses that were leaking. It is more like a weak smoke. I swear It must be coming from that pcv hose. Isn't there fumes that pass through through that hose?

 

Ummm It should have no way to crack a headlight, Is the hose comming off the black box on the back of the block?

 

Yeah it is the hose that connects to the black box from the pcv valve on the manifold. I just ordered that piece of broken hose because i concluded that it was the source of the smoke. I also found the reasoning for the cracked headlight, it is because I didn't bleed the coolant system when I refilled it after I replaced a blown head gasket. As long as the hose I ordered fixes the smoke, I should be fine.
