Tell me I'm wrong!

My 1UZ has recently started pumping oily smoke out the crankcase breather (one side has just a filter), even at idle. It still pulls decent vacuum at idle and goes hard, but i'm looking at a dead piston ring/s hey?

After all the stuff my 1uz has been through I was expecting head gaskets eventually, not pistons. Unless it ran lean a few times (never heard it ping).....

Double check your routings along with PVC.

At the moment I have a hose from the stock PVC valve side going to the valve, then to an air/oil seperator, then into the engine. If I crimp the hose while it's idling (on the engine side of the PCV valve) you can hear it start restricting the air being sucked into the manifold, so it's definitely working.
At idle there's still about 20inHg vacuum so the opposing side to where the smoke is being pumped out (TB side has filter and where the oil/smoke comes from) should be sucking, not blowing under vacuum. Which makes me think its 100% compression getting into the crank case past a piston
