Well I thought it was too goo to last. Yesterday morning on the way home from work my Auto started smoking like a trooper whilst sat at a roundabout. Well today I did a compression check and all was OK 150 in each pot. Next was the Tubby fine no leaks. I've only done 1k since I started this thread so I was stumped. I took off the tubby to find no.4 exhaust was full of oil! I called the God and we thought maybe rings or HG so Off came the head.
Well on close examination of the head you won't believe what I found. The valve stem oil seal on No.4 exhaust valve was just popping up and down and had not been fitted properly. Well I could not believe it, it was amazing how much smoke could be caused by One valve. Anyways after frantic calling round, I got the head skimmed and will refit it tomorrow.

The moral of the story 'Dont *ucking trust anyone to do a good job !'
