Was cleaning the TB out and noticed the block looked like something has been leaking down the front of it, seems to be coming from under the intake manifold? Any experts here know what it is, severity, rough estimate on cost to fix, etc?

Thanks in advance.

Looks like th pcv valve is leaking. See how it's covered in oil?

It's probably that rubber hose between the valve and the intake.

Don't know how I missed that... was expecting something more serious than that. Thanks, I'll check that out first.

That hose that elbows into the TB, anyone know where I can get that? Or is just using any hose fine

I just used a rubber fuel hose to replace that part. I believe it was 3/8

Thanks all. After reading up a bit, I found a shop in my area to do a LS6 valley cover mod to delete the PCV altogether. My car is also sucking wind like crazy. Pretty sure it's coming from the intake manifold so it might be a good time to replace the intake manifold seals; while the manifold is off they're going to just do the valley cover and delete the PCV system.

You might want a new belt too. That one is looking a bit rough on the backside. Looks way too shiny and has some odd pitting/holes/something. The water pump pulley might have had a hand in some of it. I see an odd looking spot on the belt path just below the intake bellow in the photo. At least in my opinion.

Is that the original GM radiator hose? I ask cause the original was on my car till last year when I replaced it at the same time I replaced the radiator. Still seemed pretty solid too, but everything was coming off anyway, so... Makes me wonder if the Dexcool was actually good for the hose since I've replaced some soft, squishy hoses that weren't that old on other cars using regular green antifreeze.

Thanks for the info on the belt. It's definitely in need I'm sure. Next on the list, maybe I'll see if the shop doing the ls6 valley cover will do the belt at the same time.

Original hoses as well, getting the hoses all changed is something I've wanted to do as a precautionary measure, but every shop when car is in for service days they're in good shape. 15 years and ~300k miles I'm shocked.
