Thanks Amacman, that video as entertaining as it was informative. I was unaware the CCV when bad could cause smoke after idle?

Call me faint hearted but I'm a tad bit uncomfortable running the engine without the oil stick or cap, but I will do it anyway.

I hope my smoking problem is the CCV because it seems this would be cheaper than other repairs. I'm not that sure about it being CCV because my car started smoking only 40 k kms after the PCV valve was replaced on both sides of the engine. And the winters in Melbourne are not that cold. I assume PCV is the same as CCV in my instance? This was how it was named on the invoice.

Any info or advice would be appreciated

cheers
