Still leaking oil...

[MustangGT95]

I have oil coming from uptop on the motor somewhere. I tore my lower manifold off yesterday and changed the gaskets. It appears I stopped the leak in some places but I still have a good bit leaking. It appears to be coming from the top in the back.

Is there anything else back there that could cause a leak? I have done lower manifold gasket install numerous times and I have never had one leak so I'm pretty confident I did it correctly.

What intake are you using? If it doesn't have a baffle under the PCV, it could be splashing oil out through the PCV hole, or maybe leaking between the intake and block.

I am just using the stock intake. I used a nice thick coat of RTV on the back wall. The PCV valve crommet had some play in it and it was hard as a rock so I picked up a new one today.

There is water coming from somewhere up there also. Is there a freeze plug back there?
