That won't be a big deal as I will be using a blue felpro gasket after I mod my valve cover
My thoughts exactly.

alright got the felpro gasket ordered. It will be on by tomorrow afternoon.
I had a thought today...
My intake was sucking in a ton of oil through it but the front breather was dry.
After I pulled the rear breather off the intake manifold and oil stopped coming out of it, oil started coming out of the front breather.
My front breather has not been connected to the air cleaner box because I made my own with a paint can and a cone filter and was too lazy to connect the front breather.
My thought is that because the front breather was not getting suction through the air cleaner but the rear was getting lots from the intake manifold and that is why its sucking in the oil..
Here's a pic to explain

Glad you found it, let us know.

It might not "suck" allot from the front, but should at least be free to vent.

I wouldn't rush the manifold job. You will get into allot there. Check your left motor mount, clean things up. Take a good look at the wiring and vacuum lines. Spray the exhaust (and all) bolts ASAP with PB blaster. Hit the header flange bolts. One broken bolt can really ruin your day.

Are you sure all that is necessary? Is it really leaking?

"My front breather has not been connected to the air cleaner box because I made my own with a paint can " Was it left free or did you cap that off? Truth matters here!

All that CCV stuff needs to be functional. You can't leave pieces out of that puzzle and expect good results. It doesn' hurt anything. It needs to be intact.

Nothing was capped at all. The rear was attatched to the intake manifold and the front was just dangling in my engine bay. But how about the people that put small cone filters on their front breathers? Why wouldn't they get tons of oil in their intake manifold too? And my valve cover gasket probably isn't leaking but I need to replace it anyway when I do my valve cover mod today

Maybe it came out the front because I put the rear ccv in a bottle ( a week ago because I thought it would catch oil) (which it didn't so I assume its not blow by and my compression was good in the farther cylinders).and air couldnt escape because it was too air tight?

Whoops! Sorry of me. I crossed my wires and went to the manifold gasket. Anyway, exactly, I'm suspicious people have suspected their rear main seal when it was actually one of those after-market filters plugged up inside. That front tube is 1/2 inch for a reason. When you are gassen it on a hill, there might be significant blow-by. It needs a way to get out!

Does it idle smooth? If you have oil in the intake with both lines off the valve cover, either it's the valve cover, or you have serious engine problems. Brake fluid?

It idles very smooth. And wouldn't blow by be caused by bad rings? My compression text results did not yield bad rings.
Too busy today to get the valve cover off and modded. I'll do it tomorrow afternoon.

Sounds like Cruiser has you on the right track....are you loosening any brake fluid?

maybe a centimeter every 3 months (judging by the brake booster reservoir)

MMMM, you get what I'm getting at? If there is "fluid" in the manifold with both lines off the VC, what is left? Fluid getting past the brake booster might be a thought. I suppose you could pull that big line to your intake manifold from the booster and see if it's wet inside.....

ahh i get what your sniffing at. there was a misunderstanding. fluid did not get in the intake manifold once i pulled both breathers. and i figured that's where my oil WAS going because its stayed at the full line for the past 100-200 miles the questions were; why was oil coming out of the front breather once the rear was taken off when the front was dry for 7 months?(maybe because it was in an air tight bottle not allowing air to escape?)
and why would oil even get sucked into the manifold?(maybe had something to do with the front breather not connected to air cleaner?) (or the valve cover mod needs to be done?)
we will find out tomorrow when the valve cover gets modded and everything get put in the right place. (after i clean the oil out of the lines of course)
