Ok I am going to do the plugs, Oil, Oil filter, Air filter anyway. Its has been sat up for abot 6 weeks but it hasnt got any worse on a 80 trip back down the motorway at 70-80.

I do think its the headgasket as it not eating coolant and there no bubbing in the header tank.

The air box was a abit dirty inside but the filter was not to bad (have seen worse) the MAF is the sensor monitoring the air flow by the airbox isnt it?
