I will have to revisit this plug..
Sods law says this is causing my fumes..
Well..
As its such a simple task on the 1248
I gave the car a 20 minute run..
Whipped off the airbox.. and attempted to slacken plug #4 .. it had been the tightest..
It moved ok
#3 the same
Tightened them both back down 'snug'
As the motor was still hot I removed the leads to 2 and 1 - also fine..
So all 4 plugs got wound down just a little more.
Very pleased they all moved easily.. this has been @18 months
Time will tell if its made a difference
