Anyone have any ideas on this oil leak. Pulled off the intake manifold and seems like the oil leak might be from the intake gasket?what do y'all think?

 

I think it might be easier to find if all was cleaned and reassembled. Then you might have corrected it and if not it should be easier to isolate.

 

Yea I'll clean it up and throw on new gaskets. Thanks

i just found the same thing 11/21/23 i curious to see what the problem is 408k Ford Ex 2wd]

 

So we don't need to do the job over again, If that is the oil pressure sensor in the pix, just replace that and assemble the manifold. There are no provisions for any lubricating oil to come from the manifold.

 

I have not found the root cause but I had a bit of oil in the intake. When I pulled the intake you could see a few ports has fresh oil around them. My gaskets were good but if they were bad I could see oil seeping out and running down to the valley and collecting like yours did. I’ve read oil in the intake could be as simple as a bad PCV valve but also could be excessive blow by from the rings that blows harder into the block and therefore blows harder into the PCV valve and This can carry more oil through the valve and tube leading into the throttle body and intake. When I tipped the manifold over and back I had more oil drip out so I think there is a bit more deep inside the resonator portion of the lower intake. There is no place else oil could be coming from, unless you had a blown head gasket or cracked block. Also, I’ve heard these plastic intakes can be cracked. So even with good gaskets, and of course worse in combination with bad gaskets, this could lead to oil leaks if you have a good bit of oil in your intake manifold.
