crankcase not vented on these motors?

**97RS** · 04-21-2011

i did an oil change and as i took off the drain plug i notice the oil was only barely seeping out of the crank, i thought holly **** this motor was being ran without oil and my low oil light was ****ed up and i was getting a false reading on my oil pressure gauge, so i just removed the oil cap and boom all the oil just poured out into the pan.

my question is if there is any breathers on this motor? i only see a PCV valve and a vent on the supercharger. is this fine or is there something messed up?

hows your PCV valve doing?

The crankcase HAS to be vented.

The front and read head vent through the heads then the LIM then the S/C and finally between the TB and MAF.

hmmm...Ive never noticed it being slow. I always have to keep adjusting the oil drain pan because it over shoots it

i haven't changed the pcv valve on this motor. and i see a vent on the supercharger next to the tb location. i seen allot of gtps with breathers on the oil cap location. is it there because of the same reason or is it a bad pcv?

Those are there to create a vacuum leak and drip oil all over the front of your engine during hard stops. They look cool tho

its for people who have intercoolers which block their front PCV and they're too lazy to setup the PCV properly.

u serous? lmaoo but anyways yeah you guys suggest changing the pcv? and the port next to the pcv valve goes on the side of the tb or does it go vented to the front side of the tb where there's no vacuum or into the tb where there is vacuum??

i'm unsure of L32 vacuum routing.

**97RS** · 04-21-2011

im speaking of this port on the supercharger. i have it open to atmosphere at the moment. i thought it was a breather and not for pcv function and the pcv was already under vacuum. now im just confused. any input would help.

I want one of those.....just sayin

The one that has the fiero emblem is the vacuum tree and the one that has L32 on it is the PCV cap.

both need to be sealed.

but the fiero one is for the BBV actuator, that shoudl still be functioning.
