Good eye indeed! I have a oil loss issue. I cleaned out the Fram PCV valve, but still oil loss. A buddy suggested a catch can/bottle (see red circled) to check if there is any oil coming out from the valve cover. No oil loss. I swing by another friend's place (Richard Gallant) place last night. We are thinking the valve cover leak at the back of the engine is causing this.

Good reminder, I have to remove the glass bottle, re-install the FRAM valve and reconnect the hose. Time to go off-roading this weekend!
