PCV concern Water pump took a dump so I did some wrench time to replace it. While I was under the hood I noticed something that has me concerned.
Looks like a lot of oil on the passanger side near the PCV valve. I'm going to go get a new one but I was wondering if this looks right. The hose covering seems to have receded towards the back of the motor, exposing the PCV valve. I tried pulling it forward but it won't budge. Is this how it's suppose to be, or should it be covering the valve all the way up to where it enters the intake manifold?

Is it a quick and easy job to replace the line? I just don't want to spend a lot of time stretching to reach the rear lip of the engine compartment due to painful back problems... I had to
and take a Vicodin after changing out my water pump...

So you think it looks like I have to replace the whole line as opposed to just changing out the valve?

I cant see the picture because im at work, but if the line is broken on the VC, you will need a new line. Im going through a similar problem, i had oil pouring down the back of car causing it to look like the rear main seal was leaking, so after replacing it two times and still having a leak i decided i cant have done it wrong twice and found my PCV line was split in half in the back dumping oil down the back of the block.
On another note, after reading about your fiasco, I'm beginning to wonder if maybe my line is split in a different spot and just happens to be dripping out the open end of the thick hose next to the valve, giving the illusion that the valve is to blame....

sjsingle1 is talking about the LS6 PCV conversion that gets rid of all the exterior lines. LS6 PCV and LS6 VC= the same thing.
Anyway, I've had a leak down the back of my motor lately. I'm pretty confident that the y piece in the pcv is rotted and leaking. So I'm going to redo the pcv like this guy did: https://ls1tech.com/forums/generatio...over-hose.html
It won't be a permanent solution for me, but until I have time to upgrade to the LS6 PCV, I'm confident this will suffice. No sense in spending an outrageous amount for a fragile factory piece if this will do the job just as well and hold up better. For as cheap as this is, it may be worth doing in your case too.

Right, that's just the insulating cover for the plastic pipe that runs to the back. You might check the rubber holder the pcv valve fits it for leaking, they are sort of a bad design, I replaced mine with 3/4" heater hose and clamps. Also the plastic pipe might be cracked.

I haven't been able to actually WITNESS the leak. It's not like spitting out fluid and crap when the engine is idling with the hood up. I don't understand the precise mechanics of the pcv line...does it only work while the engine is under load or after the car has been running for a while? It's frustrating because I am unable to witness the leak and pinpoint its location. I clean the area and then, boom, two days later I pop the hood and see more grime on the head under the valve. Speaking of which, it's dripping right onto a little metal rail that runs under the TB and enters some fixture on the head under the valve. What is this rail, and could it possibly be leaking the fluids causing the grime? I just assumed it was a problem with the pcv because the oil was found underneath it, but now I'm wondering if the head is leaking something around the base of that rail fixture. Again, reference the provided photo to see what I'm talking about if I'm being unclear. Thanks again for all the input, fellas.
