what would cause oil to be in this area and only this area


What do i need to do to fix it and how dangerous could it be?

 

Looks like it's coming from your PCV valve right above it. Better to leak out there than get sucked into the intake manifold.

You can search on PCV and/or 'catch can' in here and find a lot of info. I just installed the Z06 valley cover which tries to fix the LS1 oil consumption issues. I may put in a catch can as well though.

 

I'm assuming it isn't very much oil, because I don't think there any that normally runs through that area, unless I'm off. You might have a small leak in the valve cover or perhaps you could have a small leak in the hose right above it. I believe that's where the "catch can" normally installs so it could be you have a leak there and you've essentially created a catch can without the can. But I could be way off here, I haven't done the catch can mod.

Pretty sure you don't have a dangerous issue, but if that hose is leaking you could be drawing in fresh unmetered air which could cause a lean condition. Depending on how lean your running that could get bad at high RPMs.

 

Duct tape.

 

The fitting is for the steam tube.. it would not be oil leaking from there.. I would say that like there other.. check the PCV fittings.

 

I believe that's what i was. I replaced the valve yesterday (fair amount of oil in there) and sealed up some cracking hoses (thanks for the duct tape idea) temporarily until i get a ls6 conversion. Appreciate it guys, if i still have issues then i'll need to get a catch can I suppose.
