I thought I'd keep everyone posted as to progress with the 15 thou head skim.
300 tdi 145000 miles 15 thou off after blown gasket warped the head.
Early days yet but there are no problems after 250 miles. Water and oil levels are good. Less smoke on startup.
I'll post you all after 750 miles.

I think if you were going to have problems they would have showen themselfs by now, touch glyndwr's rear floor pan , keep us posted.
