Default PCV valve hose cracked

On the driver side where it connects to the intake is broken. I had a slight vacuum leak and when I went to find it I made it worse. Now it's basically not connectable. I'm going to go to VatoZone to get a hose elbow connector for it.

What will this being like this do? Should I not drive it at all or what? Also is this what's causing my cam-like lope at idle when warm? I assume so, since it's the only vacuum leak I had... that i could hear at least.

Just buy the same diameter hose, you will be fine, I had to do the same a few years back. As far as the lope at idle when warm, The vacuum leak could probably be the culprit, or a sticky EGR valve. Do the PCV valve first, if it doesnt go away move to the egr, and so on
You *shouldnt* cause any problems to drive like that for a little while, but I would get it fixed sooner rather then later

Ok, thanks. Also, I don't think it matters, but the hose isn't cracked as I said in the title, it's an elbow hose connector that the previous owner must have put on it.

The hose going to the TB from the passanger side valve cover is one solid piece of rubber except for the 90 Degree elbow sitting in the valve cover gromet. I bought a brand new one from GM being that no other hose is going to fit as nice as the OEM style.

Maybe I mis-read, I thought he was talking about the pcv valve hose, on the intake, which you can get anywhere, the hose from the pass. valve cover, to t/b, thats a different story, probably GM like you say

Nope...i actually misread! I just jumped the gun and ASSumed that he was talking about the famous hose on the TB that always breaks.

But you were right Mr. Kovacs, a piece of prob 3/8's hose bent to a 90 degree to connect to the steel line will do the trick. My apologies to you

No Prob Chris
While on the subject of the infamous breaking hose,, roughly how much did you spend on yours, because i'm evidently plagued by the same problem.

I couldn't even tell you if you had a gun pointed to my head. I can get a part number and look it up on GMpartsdirect for you.

Dont worry about it, Just thought you knew, i'll look it up, no rush.
Thats the least of my worries right now. After I get all this mess of parts back to a functioning LT1 I will cross that bridge then. What started as a "winter tune up" turned into a full on H/C swap... At least thats what I told my Wife

TB to valve cover pipe GM # 10128365

Gm Parts direct says $7.40, which usually I can get at my local dealership for lets say...3-5% more than GM parts direct, but I don't have to pay their rediciolous shipping charges in return.
