Many thanks everyone, I've cleaned it all off now and will keep an eye on it. It's realy not alot on there just surprised me when I got the engine cover off. Oil usage on the car is quite reasonable, 250ml to 500ml every 4 or 5k.
I've just replaced my F revision PCV with the current N revision, also about to replace the original bosch factory spark plugs with OEM NGK's, air filter and do an oil change. Looking forward to seeing how it runs. Had minor misfires showing occasionally on VCDS, never enough to trip a fault though.
I'll check the cylinder head cover bolts to check there all torqued up, 10nm I beleave they should be.
I also got some of the coilpack grease that according to ELSA should be re-applied to old coilpacks when fitting new plugs (new coilpacks come pre greased). £20 for a small tube from dealer
