318 with blow by

So here's a quick PCV system test (first buy a new valve and hose, $10 or so). On the valve cover opposite the PCV valve you have a hose running to the air cleaner. With the engine at idle, plug this hose with your thumb. You should feel vacuum build after 1-2 seconds. If your idle speed picks up once this vacuum builds, your intake valve guides are worn and leaking, acting like 8 little vacuum leaks. On a high mile 318, I would expect this, especially if you use a little oil, no biggie. BUT if the engine blows your thumb off the hose and builds pressure not vacuum at idle you have massive blow-by. Your rings are probably stuck, broken, or seriously worn out.
