Title says it all.

I have fresh (unburnt) oil leaking onto a/c compressor and dripping down to the garage floor. I cannot get a good view of the passenger side head at the front of the block where the majority of the oil seems to be bleeding from. I can also see both gaskets have fresh oil coating them and slightly seeping as well when viewed from underneath on a lift.

There is no evidence of coolant leaking. The engine is not over heating and there is plenty of coolant in the reserve tank cold & hot.

The engine is running strong; with no tell tail signs of an issue.

So how it possible for oil to be leaking from my heads with no coolant leaking out at the same time?

Thoughts?

The first thing that comes to mind is the valve cover gasket(s).

Both are dry as bone and nice clean aluminum.

Valley cover leaking, oil running down at edges of the heads?
PCV working?

x2 on that my oil pressure port was leaking and I thought my head was leaking also when its behind every thing its hard to tell

Oil could possibly be running down the heads instead of seeping from the gaskets. There is a bit of moisture under my throttle body at the bottom of the air intake manifold but it looks pretty old and not too fresh. I believe I'll clean this area and see if it accumulates new moisture in this area.

I have no error codes for PCV problems and my catch can is empty.

I'll look into this as well.

My oil pressure gauge stays within normal operating ranges from idle to WOT; if the port is leaking would the gauge still operate properly?
