Hoping you guys can shed some light on this problem I cant seem to figure out. Since the motor was out I decided to clean it up some and replace some of the seals that were leaking a bit. When I pulled the intake manifold off there is oil in every runner and in the head and on the valves. Its only in the lower intake runners not the upper part of the manifold.
I know the turbo is not leaking oil, I have no EGR, PCV valve, nothing that could bring oil into the intake manifold. Kinda lost on this one. I have pulled the intake before and there was oil in there before and I cleaned it all out. So its coming from some where.

Yea thats what Im thinking but the head was rebuilt 35k ago with the motor. I did not replace the guides but the seals were. It just doesn't make sense that that would all be leaking at the same time. Car doesnt smoke much if any so im not sure if its burning much oil. Doesnt really add up

Well the mileage does not really matter. Seals can fail prematurely, etc.
I just found out today that my expensive ass head has a serious valve guide leak. With only 15k miles on the build, I pulled the turbo manifold off today to replace the gasket and a sheared stud, and found that my guides were wet with oil. The machinist that removed the OE guides and installed the bronze guides fucked it up.

Yea I know milage doesn't really matter, but for all of them to be leaking at the same time doesnt make sense. Is there anyway to verify that they are or are not leaking.
