Enlarging Breather Holes? right bank rocker cover, 3.0 V6 VE Commodore

Nothing better to do than look for an argument clown ? Do you have a 3.0 ? Look up the stability control fault logs and what it is a result of ? Just because you have never seen it; doesn’t mean it’s not.
Go to sleep mate; your a clown

Excuse me kind sir. Could you please point the way to the nearest circus? I appear to be lost.

Did it today. 3mm single hole, 2mm for each of the dual holes. Mine were nearly clogged. No real issues that I've noticed previously. Just takes a bit of time to do. Hardest was figuring out that plastic elbow clip.

Did it come out ok?
How many kilometres has the car done please?

Sludge and carbon build up are both signs of poor servicing. Drilling the holes out, using synthetic oil and more regular oil changes will help you avoid timing chain issues caused by dirty sludgey oil and blockages.

Came out easily with some pliers. Bit of wiggling back and forth.

210,000km ish.
