    VC Gasket/Plugs Question

    I changed my spark plugs today. They all looked fine but cylinder 5's threads had a light coat of wet oil on them. The tip was fine, just the threads. Does this mean my valve cover gasket has a small leak? Car has just over 30,000 miles. RB PCV in VC.

    Thanks.

    That's classic VCG symptoms. Oil on the threads, but not on the business end. Alternatively it could be some oil that spilt at some point in time, though cyl 5 is getting back towards the firewall so IDK. I'd lean towards valve cover gasket though.

    I recently changed all those parts. VCG is still the original. I'm going to dealer it tomorrow and see what happens.

    So valve cover gasket is the only thing that can cause wet threads?

    If the electrode is dry, that’s all I can think of. The gasket seats right above it, obviously. It’s either that or a freak oil spill, which is also certainly possible.

    One time, while doing an oil change, I was too lazy to find my funnel and decided to try my luck with pouring oil directly into the engine. Didn't work out so well on one of the bottles and ended up spilling oil. The next time I did spark plugs, the hole was about half filled with oil and the plug's threads were black. Cleaned it up installed my new plugs. Checked again next service and no more wet threads.

    I can see this as a possibility but why only cylinder 5? Every other one was fine.

    i had wetness on the threads on cyl 5 plug.

    i did a new vc and gasket for other reasons after that, and plugs been dry since. I wouldnt jump to conclusions though, if u did your plugs urself just give it about a week or two and pull cyl 5 and check again.

    FWIW, 165k km and the VCG only just started leaking. Probably going to R&R it tomorrow.
