For the first time since we've had it (6 years) it's flumped the MOT - excessive blue smoke (or so he says - I can't see much at all, in fact hardly any!) but it passed the emissions funnily enough.
I got it back, changed the oil, added some of that goo which alledgedly reduces smoke and cleaned the plugs, only to have it fail again today on the same thing. I did notice the plugs were a bit sooty, however.
Bar this, is there anything else I can do? I can fully appreciate the valves guides/pistons etc could be worn after 87k but I've not the time to be messing about at the moment with it and it'll have to go as we use it constantly if i cant get it thru. BTW, I did the HG recently - could that be a factor? I do have it booked in at another testers on wed.
