Hey guys, I had a feeling to check my spark plugs earlier to see if they were ok, and it looks like there's a bit of oil on them :/ Does this look normal? Or is it a leaking gasket of some kind? (the car is a 2003 MK4 Golf 1.6 16v)

thanks smile

Next time you get that feeling, ignore it. Those plugs are fine, and taking plugs out just out of curiosity is asking for trouble.

I'm of the view if you're going to.the bother of removing plugs to check them you are as well just putting new ones in.

As said above, those plugs look relatively new and display nothing to be concerned about.

Do yourself a favour and change your plug brand to NGK, as mentioned you have no issues apart from Bosch plugs rolleyes

Nothing wrong with Bosch as a plug maker. The only issue is people using the wrong plug for their application, the brand is irrelevant.

101905601 is VW p/n for the correct Bosch spark plug.

It is WISE to put a bit of oil/copper grease onto the spark plug threads before installing as a seized in spark plug is a head off nightmare.

It's when the tips of the plugs and the very top above the threaded section are covered in oil that you start to wonder if you have knackered valve stems/piston rings or if the internal rocker gasket has gone which allows oil to run down the insides of the spark plug chamber. You will also find the HT leads have a coating of oil to if the upper gasket has failed.
