Default Where is the PCV Valve?

I know this may seem like a stupid question but can someone please tell me where the PCV valve is on a 1995 LT1 Corvette? I wanted to replace the valve as part of routine maint. but I have no idea how to find it.

Under the drivers side fuelrail cover. One side of the U shaped hose goes to it.

That hose gets awful brittle, when I replaced mine the hose was hard and it cracked. Special shaped hose too. A new one is soft and supple, I guess the heat gets to it after a while.

You have to be careful not to break the surrounding vacuum lines, too.

Where did you find replacement hoses? There is a ribbed u-shaped hose just off to the side and behine the TB on the passnger's side of the intake on my LT1. It is cracked and looks like hell. I have no idea where to get a replacement short of the dealer... and I'm not sure that they would know what I'm talking about!

Call Chris at Superior Chevy. They are most likely discontinued but you'll want the part numbers. From there contact Vintage Parts and give them the part number. 1-877-846-8243


For the vacuum harness assembly that goes from the EGR on the driver's side it is: 10105325
