So today when I pulled my rear pcv hose out of the valve cover some kind of liquid ran out of both the valve cover and the hose. I started pulling a few other things apart and noticed their is a puddle of this stuff in my intake just before my throttle body.

All I have is a phone so the pictures suck but this milky crap is almost plugging my pcv hose and valve and I'm wondering if this could be because of coolant leaking into my oil or what.

Isn't this the reason people install a catch can? cause oil can end up in the intake/ or more commonly on Forced Induction cars, the charge piping?

looks like the infamous LIM gasket failure...and if you got coolant under your t.b. thats more then likley the culprit...headgaskets leaking..youll either see it coming down the block..usually the corners leak the most, or youll overheat and have all kinds of white smoke pouring out if your exhaust

The oil is going through the pcv in both directions and besides that the whole point of this thread is that this isn't just oil that's turning up in my intake it is mixed with some kind of liquid possibly coolant.

Also it is not leaking externally at all as far as I can see. My coolant level is low but I also have a hose leaking so its hard to tell.

Precautionary measure, just do the engine swap.

I would do that /\. If you need any help let me know. I have dealt with countless LIM's and did my engine in June. Another set of hands and eyes is always nice.

how is the oil on your dip stick, if it is the same, you have big issue, if it is layerd, milky on top, reg on bottom, not as bad. if your dip stick is ok, some build up is normal, but yours looks a little exsessive. have you had alot of rain lately or really high humidity? most likely it is a leaky gasket though.

Leaky LIM or heads/head gasket.
