    Spark plug experts please

    Changed my spark plugs on my 1.8t bex today, all went well. My question is.... from the pic is this a healthy spark plug i removed? And also how much oil is acceptable where the SP sits? Ie, looking down in to the apperture before removing the plug there was a small collection of oil. Not loads just a few drops sat on a machined shoulder.
    Bosch super 4's went back in, done my air filter too. Car got some love today!

    mate sounds like your rocker cover gasket is on its way out, thats what happened to mine didnt take the plugs out though and when i swapped mine out the other week they were dry no signs of oil penetrating into the plugs and I changed my gasket last summer.

    I would say from that plug the engine is fairly healthy.. its hard to read a plug nowadays cos there is nothing decent left in the fuel..
    Tip colouring is gentle throttle, colour deep in the plug is full throttle, timing can be read from the earth electrode, plugs can tell you everything..

    as above thats a nice healty running motor

    and change your rocker cover gasket and all will be well with the oil the last thing you want is for the oil to earth the plug cap and cause the car to stop

    Thanks for the replies, it runs sweet except for the first few seconds of start up on cold mornings. Engine shakes on its mounts like its gonna fall out for about a second then all is fine. Its hard to describe though.

    Plugs look good.
    Re poor cold start. Check to see if you have the old black coolant temp sensor if you have replace it with a genuine revised green Vag CTS.

    I've got the same Bosch FR7KPP33+ plugs on my 2003 standard 1.8T . What gap should they be ?
    I've also got the same issue with oil so I'll be replacing the rocker cover gasket in the very near future.
    Cheers

    im no expert but imo the plug looks too clean on the insulator. should be lightly tanned . So i looked it up and my answer would be a shameless copy from another source.

    A clean white insulator firing tip and/or excessive electrode erosion. This is often caused by advanced ignition, timing, poor engine cooling efficiency, lean air/fuel mixture, or leaky intake.

    Check the plugs correct, fit some good quality ones and check correct gaps, makes all the difference in turbo cars, more boost = smaller gap too.

    Is the CTS also an issue on B6 cars ? Are there different versions of the green one ?

    I found this article, written in the states.

    AudiWorld Tech Articles

    Can anyone in the UK confirm that the green one can / should be used to replace a "normal" 2003 B6 version
    Are the electrical connectors the same ?
    Thanks

    Connectors are the same. Use a genuine VAG green CTS only or you'll be buying twice.
